Product Description

The Joint Jacket is specifically designed for tough environments. Made from durable Polyurethane, it can handle most of what you throw at it. It’s made from specially formulated rubber that resists many chemicals, including Oil, Grease, Solvents, Fats, and Fuel. It’s Abrasion and Tear resistant well as being UV and weather resistant. Amazingly, It’s elastic enough to stretch over and over to hold tight for years.

Abrasion resistant
Parts made of polyurethane will often outwear other materials by a margin of 5 to 1 when severe abrasion is a factor. It has been proven to be vastly superior to rubber plastics and metal in many applications.

Oil and solvent resistant
Polyurethane has excellent resistance to oils, solvents, fats, greases and gasoline. All the stuff your U-joint will encounter.

Load bearing capacity
Polyurethane has a higher load-bearing capacity than any conventional rubber. Because of this characteristic, it is an ideal material for load wheels, heavy duty couplings, metal-forming pads, shock pads, expansion joints and machine mounts.

Tear resistant
Tear-strength ranges between 500-100 Ibs./linear inch, which is far superior to natural rubbers. As a result, urethane is often used as drive belts, diaphragms, roll covers, cutting pads, gaskets and chute liners.

Weather resistant
Polyurethane has outstanding resistance to oxygen, ozone, sunlight and general weather conditions.

Offers extremely high flex-life and can be expected to outlast other elastomer materials. Dust boots, bellows, diaphragms, belts, couplings and similar products are made from urethane for this reason.

Heat and cold resistant
Continuous use below 225°F is within its allowable specifications. At low temperatures, The Joint Jacket will remain flexible down to -90°F.

    I got mine for free off pirate and it’s pretty handy. So much easier than using electric tape… fit nicely on a 1350 joint.

    Thanks again for such badass jackets!

    Really handy and convenient. I was able to put my spare retaining clips right on the caps than slip these over the joint holding the snap ring and caps both in place. Need to order more

    I have used these several times and they always worked just the way they are supposed to. It is one of those “face palm” ideas you see and say “why did I not think of this”. I would think the only thing to go wrong with them is if they are lost, so get a couple pair.

    These things are great at keeping U-joints safe. I also use them for other small items
