If you’ve ever spent time on a job site where drilling operations run 12-hour shifts, or you’ve seen a piece of specialty drilling equipment go down mid-project because of unexpected moisture, you know how costly and frustrating those delays can be. As a supplier of other drilling equipment—think the often-overlooked auxiliary tools that keep core drilling rigs, directional drills, and underground excavation equipment running smoothly—my team and I have spent years troubleshooting how to protect these often-hard-to-insulate, custom parts from water and humidity. Unlike main rig engines or hydraulic pumps, auxiliary drilling equipment (things like drill pipe elevators, torque wrenches, control panels, and portable drill site data loggers) tend to be spread out across a job site, left exposed to rain, condensation from cool underground air, or splashes from drilling mud. Over the years, we’ve developed waterproof and moisture-proof measures that are tailored specifically to these tools, and today I want to share what works, what doesn’t, and why one-size-fits-all solutions just won’t cut it for other drilling equipment. Other Drilling Equipment
Let’s start with the most common culprit that hits our auxiliary tools: unplanned on-site moisture exposure. Main rigs often come with built-in weather enclosures, but their companion tools? Drill pipe elevators might be set up 50 feet from the main rig to load pipes, control panels could be in a open-sided cart near the mud pit, and data loggers—tiny, sensitive devices that track drill depth and rotation speed—are sometimes left on the ground when a crew has to move quickly during a shift. Last year, we had a customer in West Texas call us in a panic: their directional drill’s torque wrench had shorted out during a rainstorm, delaying a $2 million pipeline project by 3 days. They’d used a generic plastic tarp to cover it, but the tarp trapped condensation against the metal handle, and moisture seeped into the wrench’s electrical connections. That’s when we realized we needed to move beyond basic tarping and apply protection that’s specific to each type of auxiliary drilling equipment.
First, let’s talk about enclosures, but not the generic kind. For our electrical auxiliary tools—control panels, data loggers, and torque wrenches—we rely on IP-rated enclosures, but not just any IP rating. IP67 is standard for many industrial tools, but we’ve found that for auxiliary drilling equipment, IP65 is often more practical because it balances water resistance with airflow. Data loggers, for example, need to release internal heat to avoid overheating during long shifts; an IP67 enclosure is fully waterproof when submerged, but it’s airtight, so the logger’s internal temperature can spike 10 degrees higher than outside, which causes condensation to form inside the casing. That’s a problem—moisture inside the enclosure is just as bad as moisture outside. So for these electrical tools, we spec IP65-rated enclosures with vented gaskets. The vents are small enough to keep out spray and light rain, but they let air circulate, preventing internal condensation. We also add a small desiccant pack inside every electrical auxiliary enclosure when we ship it, but we make sure the pack is accessible—crew members can swap it out every 3 months, or after a job in a high-humidity environment, without having to open the entire enclosure. For non-electrical metal tools, like drill pipe elevators and heavy-duty wrenches, we don’t just use paint. We apply a two-part epoxy coating that’s designed for underground and outdoor metal use, and we add a zinc-rich primer first to prevent rust. Drill pipe elevators are used to lift 500-pound pipes, so the coating has to be durable enough to handle constant impact from pipe weights, not just water. Last year, we tested this coating on a set of elevators for a mining company in Canada, where winter brings freezing rain and salt brine on job sites; those elevators still show no rust after 18 months of use, whereas uncoated elevators would start showing rust in 6 months.
Next, we address the issue of on-site storage, which is a huge pain point for many crews. We often tell our customers that even the best enclosure won’t help if a tool is left sitting in a puddle overnight. For auxiliary drilling equipment that’s not in use—like extra drill pipe clamps or portable pump units—we recommend custom-fitted weatherproof cases, not just the foam-lined hard cases you’d buy for a camera. These cases are made from high-density polyethylene (HDPE) that’s resistant to oil, drilling mud, and UV rays, which is important because many job sites have oil or mud splashes that can eat away at regular plastic. We also add a rubber gasket around the lid that’s compressed when the case is latched, creating a watertight seal. For larger items, like portable drill site power generators that power auxiliary tools, we’ve started offering custom-built shelter kits. These shelters are lightweight, easy to assemble in 10 minutes, and have a sloped roof that directs water away from the generator. They’re also breathable, so they don’t trap heat inside, which is another common issue—if you enclose a generator without airflow, it can overheat, and the moisture inside will cause rust on the metal frame.
One of the most underrated moisture threats to other drilling equipment is condensation, especially in underground drilling operations. When you’re drilling 1,000 feet below ground, the air is cold and humid, and when a crew brings a tool up to the surface, which is warm and dry, condensation forms on the tool’s surface. This is called “sweating,” and it’s a major problem for metal parts because it leads to rust, and for electrical parts because it causes short circuits. To fight this, we’ve started including anti-condensation treatment as a standard add-on for metal auxiliary tools. It’s a thin, invisible coating that we apply during manufacturing; it works by repelling water molecules, so when a tool goes from cold underground to warm surface air, no condensation forms. We tested this treatment on drill pipe tongs for a customer doing underground utility drilling in Ohio, where they alternate between 40-degree underground air and 80-degree surface air in the summer. Before the treatment, the tongs would rust every time they were used for 6 months; after applying the anti-condensation coating, they showed no rust after 12 months. We also recommend that crews acclimate electrical tools to surface air slowly, instead of bringing them up directly from underground. For example, if a data logger is used 1,000 feet below ground, they should leave it in its IP65 enclosure in a shaded area at the surface for 30 minutes before opening it, which gives the tool time to adjust to the temperature and humidity, so no condensation forms on the internal circuits.
Another area we focus on is seals and connectors, which are often the first point of failure for auxiliary drilling equipment. Hydraulic connectors on portable pump units, for example, are exposed to mud, water, and vibration, so standard rubber seals can degrade quickly, letting moisture in. We now use Buna-N rubber seals for most hydraulic connectors, which are resistant to both water and oil, and we add a layer of Teflon tape around the connector threads to create an extra barrier. For electrical connectors on control panels and data loggers, we use sealed, weatherproof connectors that are designed for industrial use, not the standard consumer connectors you’d find on a phone charger. We also label all connectors clearly, so crews don’t mix up sealed and unsealed connectors when assembling tools on a job site. Last year, a customer in Australia had a problem with their directional drill’s control panel: water got in through an unsealed electrical connector during a monsoon, and it cost them $15,000 in repairs and delays. Since switching to our sealed connectors, they haven’t had that issue, even in areas with heavy monsoon rains.
We also can’t forget about regular maintenance, because even the best waterproof measure won’t work if it’s not cared for. We create custom maintenance checklists for each type of auxiliary drilling equipment we supply, which includes monthly inspections of seals, coating integrity, and desiccant packs. For example, every month, a crew member should check the rubber gasket on the IP65 enclosure of a data logger for cracks, because a small crack can let in water over time. They should also inspect the epoxy coating on drill pipe elevators for chips, and touch up any chips with the same coating we use during manufacturing, to prevent rust. We also offer annual on-site maintenance services for our customers’ auxiliary drilling equipment, where our technicians come in, inspect all tools, reapply coatings if needed, and replace seals and desiccant packs. This has become a popular service because many drilling crews are focused on getting the job done and don’t have time to do detailed maintenance on every auxiliary tool.
Now, I want to be honest about what doesn’t work for other drilling equipment. Generic waterproof sprays, for example, might work for a jacket, but they wear off after a few uses and don’t protect against impact, which is a constant on a job site. Plastic tarps, while convenient, don’t provide a long-term solution because they trap moisture, as we saw with that West Texas torque wrench incident. Even some “industrial-grade” enclosures might not work because they’re designed for general industrial use, not the specific conditions of drilling—like constant exposure to drilling mud, which is corrosive, or extreme temperature swings between underground and surface. That’s why we tailor every protection measure to the specific type of auxiliary drilling equipment, not just apply a one-size-fits-all approach.
As a supplier of other drilling equipment, our job isn’t just to sell tools—it’s to make sure those tools work when our customers need them, no matter the weather or job site conditions. We’ve learned over the years that the best waterproof and moisture-proof measures aren’t just about keeping water out; they’re about preventing condensation, protecting against corrosion from mud and salt, and making maintenance simple for crews who are already stretched thin. If you’re dealing with constant delays because your auxiliary drilling equipment is failing due to moisture, or you’re looking for equipment that’s built to withstand tough job site conditions, we’re here to help. We can work with you to assess your specific job site needs, recommend the right enclosures, coatings, and maintenance plans, and make sure your auxiliary tools keep running, even when the weather doesn’t cooperate.
