Perfect for capping off fuel lines or other fluid lines when disconnecting lines.

These caps do a great job of covering ð openings of AN-6 lines to keep debris out while getting ð lines in place. No, they aren't for test pressurizing ð lines, just keeping foreign material out. Note that these are for male fittings. I consider these a must-have when making AN-6 lines.

The cap on my 3oz tube of dielectric grease cracked. I can't seem to find the original caps anywhere so I got these and they fit perfectly. Very happy, plus now I have extra caps for tubes of RTV and whatnot.

These are awesome. Used them on my Acura integra valve cover while getting the motor set up tuned in. Tight fit and didn’t leak although I wouldn’t trust them on the oil pan lol.

I used these to protect threads on my reloading dies when in storage. Just helps to keep finger salts off of the threads as well as making sure threads aren't marred or dinged. They have a nice snug fit on my LEE die sets, and I haven't seen anything out on the market like them.I would recommend for anyone who has a large number of dies, who doesn't store them in turrets or presses. If you need male inserts for your turret positions or presses, take a look at this product:
