Introduction: DIY Thread Protector O-Ring

By

Thread protector o-ring got lost or worn out? Now your thread protector starts walking loose? Here’s how to get by until you find a proper replacement or keep repeating because it’s cheaper and it works.

Supplies

Masking tape
Gasket maker (your choice)
Patience

Step 1: Mask the Threads and the Barrel

Mask around where the o-ring should be.

Apply gasket maker uniformly. I had a tube of Permatex Ultra Black that’s good for oil pans and that’s what I applied using my gloved finger.

Follow gasket maker instructions for cure time. In my case 24 hours.

Step 2: Unmask

Carefully remove masking tape. The gasket should stay put and hopefully you’ll end with cleaner lines than mine.

Step 3: Install Thread Protector

The gasket should get squeezed back as you torque down the thread protector.

Try unscrewing it gradually. You should notice that it takes a bit more effort to unscrew with the gasket now.
