6 Replacement Items You Can Use To Repair HAZMAT Suits
6th Nov 2025
Your team relies on HAZMAT suits to stay safe in dangerous environments. When these suits fail, you need replacements fast. But here's the thing: you don't always need a brand-new suit. Sometimes you simply need the right replacement parts to get back to work. This guide walks you through six replacement items you can use to repair HAZMAT suits and keep your operation running smoothly.
ChemTape
ChemTape is one of the most valuable tools you'll have on hand. This specialized tape seals seams, patches holes, and closes gaps in your chemical-resistant suit. Most standard tapes fall apart when they come into contact with hazardous materials. ChemTape doesn't. It sticks through moisture, chemicals, and temperature changes that would destroy regular duct tape.
You apply ChemTape directly to the damaged area. The tape creates a waterproof barrier that prevents liquids and vapors from penetrating the suit. It works best on small tears and punctures, the kind of damage that often occurs in the field.
One roll can last through multiple repairs, so you save money compared to replacing entire suits. Here's what makes ChemTape effective in the field:
- Immediate adhesion: The tape grips the suit material instantly with no waiting time.
- Chemical resistance: It withstands exposure to most industrial chemicals and solvents.
- Durability: It maintains its seal through the entire duration of your work.
- Easy application: Your team can apply it quickly without special tools or training.
Keep several rolls in your safety kit. Your workers will use it more often than you expect. When damage happens during a shift, ChemTape provides a quick fix that keeps people working safely until you can perform more permanent repairs.
Digital Pressure Test Kit

A Digital Pressure Test Kit checks whether your suit maintains proper pressure during use. HAZMAT suits depend on consistent pressure to keep hazardous materials out. When the seal fails, pressure drops, and protection disappears.
This kit includes a digital gauge that measures pressure in real time. You connect the gauge to your suit's pressure port and run a test. The gauge tells you the exact pressure reading and alerts you to any drops. Most kits display pressure on a clear, easy-to-read digital screen.
Regularly testing your suits prevents dangerous failures during work. You catch small leaks before they become big problems. A suit that failed a pressure test gets repaired or replaced before it puts anyone at risk. You protect your team while reducing liability.
Digital pressure test kits are compatible with most modern HAZMAT suits. They're portable so that you can test suits at your facility or out in the field. Battery-operated models run for hours on a single charge.
Your safety director can train workers quickly on how to use them. Once your team learns the process, pressure testing becomes routine maintenance rather than a complicated procedure.
Exhalation Valve for Drager Chemical Suits
The exhalation valve on your Drager chemical suit controls how air leaves the suit during wear. This valve prevents backflow of outside air while letting internal moisture escape. When this valve fails, your workers feel uncomfortable, and the suit's effectiveness drops.
Replacing a Drager exhalation valve takes minutes. The old valve unscrews, and the new one screws in. No special tools. No complicated procedures. Your maintenance staff handles this repair without sending the suit to a service center. You keep the suits in operation instead of waiting weeks for repairs.
Drager exhalation valves wear out from regular use. Heat, moisture, and repeated cycles break down the internal seal. When workers report difficulty breathing or moisture buildup inside the suit, the exhalation valve is usually the culprit. Replacement valves cost significantly less than new suits. Stock these valves in your maintenance area, so you always have one available.
Quality matters with exhalation valves. Buy replacement valves explicitly designed for Drager suits. Generic valves don't fit properly or work as intended. Your workers deserve parts that function correctly. Proper valves maintain the suit's integrity and keep your team protected.
Exhalation Valve for Pirelli Suits
Pirelli suits use a different exhalation valve design than Drager models. You can't swap these valves between brands because each brand builds them differently. Pirelli exhalation valves have their own specifications and requirements.
The Pirelli valve design focuses on minimizing resistance during the worker’s exhalation. This ease of exhalation reduces fatigue during long work periods. The valve opens smoothly and closes securely. When the valve degrades, workers notice they must work harder to exhale. This increased work signals it's time for replacement.
You replace Pirelli exhalation valves the same way you handle Drager valves; unscrew the old one and screw in the new one. The job takes just as little time. Your maintenance team doesn't need advanced skills. Basic training is enough to get this work done correctly.
Keep Pirelli exhalation valves in stock separately from your Drager supplies. Mixing them up causes problems. Your workers can't use the wrong valve in their suits. Label your storage clearly so your team grabs the correct replacement every time. This simple organization prevents delays when urgent repairs are needed.
Butyl Gloves, Guardian CP-25

Your workers wear gloves inside their HAZMAT suits to protect their hands. Butyl gloves provide superior chemical resistance compared to latex or nitrile options. Guardian CP-25 butyl gloves are built tough for industrial work.
These gloves resist solvents, oils, and most hazardous chemicals. They flex naturally, so your workers maintain dexterity while handling equipment or materials. The gloves don't tear easily during rough work. They stay intact through extended shifts in demanding conditions.
Guardian CP-25 gloves come in various sizes to fit your entire team. Get the right size, as one that’s too small can restrict circulation, while larger ones can slide off during work. Your safety director should stock multiple sizes in your equipment room. When someone damages a glove during their shift, they can replace it immediately.
Butyl gloves are thicker than standard work gloves, so they may feel awkward at first until you get used to them. Workers new to butyl gloves often think they're too stiff at first. Within a few hours, most people adapt to the feel.
The superior protection is worth the minor adjustment period. Your workers will appreciate the durability once they realize how long these gloves last compared to cheaper alternatives.
Glove Insert Cones
Glove insert cones attach to the inside of your HAZMAT suit's glove ports. These cones create a seal between the glove and the suit material. Without a proper cone, gaps form, and contamination seeps through. Insert cones to completely prevent this failure point.
Over time, cones degrade from repeated insertions and removals. The seal weakens. Contamination risk increases. Replacing cones restores your suit's integrity and keeps your workers safe. New cones cost far less than a new suit.
Installing glove insert cones takes skill and attention to detail. The cone must seat properly inside the glove port. If installed incorrectly, it won't seal effectively. Your maintenance staff should receive proper training before attempting this repair. Once trained, they can handle replacements routinely without complications.
Check your cones regularly during your maintenance inspections. Look for cracks, discoloration, or visible wear. Degraded cones fail without warning.
Replace them before they cause problems during critical work. Your safety director should establish a replacement schedule based on how frequently your team uses these suits. Regular replacements prevent unexpected failures that put your workers at risk.
Keep Your Team Protected and Your Suits in Service
Your HAZMAT suits protect your workers in dangerous environments. When damage occurs, you have options beyond replacing entire suits. Stock these six replacement items for repairing HAZMAT suits in your facility, and train your maintenance staff on proper installation. They’ll extend the life of your equipment, reduce costs, and ensure your workers stay safe every single day.
