A drysuit is one of the most important pieces of gear for divers, paddlers, and anyone who spends time in cold water. It keeps you dry and safe by sealing out water at the neck and wrists. However, these seals (also sometimes referred to as ‘seams’) often wear out over time. As such, learning how to replace a drysuit neck seal and drysuit wrist seal is a skill that can save you money and extend the life of your suit.

In this guide, we will walk you through the process step by step to ensure that you can replace your drysuit neck seal and wrist seal with confidence.

Why and When to Replace Your Seals

Your drysuit seals are made from latex or neoprene. They are flexible but not indestructible. Some common reasons seals fail include:

• Sunlight damage from UV rays
• Stretching from repeated use
• Small rips or tears from fingernails or sharp objects
• Contamination from oils, sunscreen, or chemicals

Furthermore, you know it is time for drysuit neck seal replacement or drysuit wrist seal replacement when you see cracks, deep wrinkles that do not go away, or leaks during use. If the seals feel sticky or brittle, they are also at the end of their life.

Safety Note: Replacing seals is an advanced repair. If done incorrectly, the seals can fail underwater, which is dangerous. Always work carefully, and if you are unsure, consider professional repair services.

Preparation: Tools, Materials, and Workspace

Before you begin, gather everything you need. Having the right tools and a clean workspace makes the job easier and safer.

New Seals

• Latex seals are the most common. They are flexible and easy to trim.
• Neoprene seals are thicker and warmer but harder to install.
• Neck seals come in conical or bottle shapes. Wrist seals are usually conical or cuff style.
• Make sure you buy the correct size. Measure your neck and wrists, then choose seals that can be trimmed to fit snugly but comfortably.

Adhesives and Chemicals

• Use a flexible contact adhesive such as Aquaseal or Bostik. Do NOT use super glue or epoxy.
• To clean old adhesive, you need a solvent like Toluene or MEK. These are strong chemicals, so work in a well-ventilated area and wear protective gloves.

Tools and Accessories

• Sharp scissors or a utility knife for cutting seals.
• Sandpaper or abrasive pads (80 to 120 grit) for scuffing surfaces.
• A wooden dowel or smooth bottle to stretch seals during installation.
• Masking tape to mark clean glue lines.
• Nitrile or latex gloves to protect your hands.

Set up a clean table with good light. Lay out your drysuit flat and make sure you have enough space to work without rushing.

Removing the Old Seals

Step 1 – Locate the Seal Joint: Find where the old seal is glued to the drysuit fabric. You will see a line where the adhesive stops.

Step 2 – Cut the Seal: Carefully cut the old seal off, leaving a small rim of rubber attached to the suit. This prevents you from cutting into the fabric.

Step 3 – Remove Old Adhesive: This is the hardest part. Use your solvent and a cloth to gently rub away all traces of old glue and rubber. Take your time. The surface must be completely clean and dry before you move on. Any leftover adhesive will weaken the bond of the new seal.

Installing the New Seals

Step 1 – Prepare the Surfaces: Lightly sand the inside edge of the drysuit fabric and the part of the new seal that will be glued. This roughens the surface so the adhesive sticks better. Wipe both areas with a clean cloth and solvent to remove dust and oils.

Step 2 – Apply Adhesive: Brush a thin, even coat of adhesive onto both the drysuit fabric and the new seal. Let it sit until tacky, usually 5 to 15 minutes. Check the instructions on your adhesive for exact timing.

Step 3 – Bond the Seal: Align the new seal with the suit opening. Press it firmly into place. Contact cement bonds immediately, so work carefully and avoid wrinkles. Use a dowel or smooth tool to roll over the joint, pressing out bubbles and ensuring full contact.

Step 4 – Curing Time: Leave the suit to cure for 12 to 24 hours. Do not rush this step. If you use the suit before the adhesive is fully cured, the seal will fail.

Step 5 – Trimming for Fit: Once cured, try on the suit. The drysuit neck seal and drysuit wrist seal should feel snug but not painful. If they are too tight, trim them carefully. Most latex seals have score lines or rings. Cut one ring at a time until the fit is comfortable. Never cut too much at once.

Final Inspection and Testing

• After trimming, inspect the bond line. Look for gaps, bubbles, or areas where the seal is lifting. If you see problems, reapply adhesive before using the suit.
• Next, test the suit in shallow water. Put it on and check for leaks around the neck and wrists. It is better to find issues in a safe environment than during a dive or paddle trip.

Tips for Longer Seal Life

Replacing seals takes effort, so you want them to last. Here are simple tips to extend the life of your drysuit neck seal and drysuit wrist seal:

• Store your drysuit in a cool, dark place away from sunlight.
• Rinse seals with fresh water after each use.
• Avoid contact with oils, sunscreen, or fuel.
• Use a protectant to keep latex flexible.
• Do not fold seals sharply when storing the suit.

With good care, seals can last several years before needing replacement again.

Final Thoughts

Learning how to replace a drysuit neck seal and drysuit wrist seal is a valuable skill for anyone who relies on their suit for safety and comfort. The process requires patience, the right tools, and careful attention to detail. By following the steps in this guide, you can extend the life of your drysuit and enjoy more time in the water without worrying about leaks.

Also, always remember that safety comes first. If you are not confident in your repair, seek professional help. Regardless, if you take your time and follow the instructions, you will have a suit that feels almost new. By replacing your drysuit neck and wrist seals, you can save money, take ownership of your gear, and make sure it is ready when you need it most.
