🔧 High-Performance Quick Release Valve (QR-1C) - Superior Replacement for 289714 KN32041 Review

My 1996 Peterbilt 377 was losing air and wouldn't budge. YouTube University informed me that this part is the problem. Revain is the only place you can buy this part at an affordable price.

Great item! That's the easy part, but it's no fun when someone fails. My air system was bleeding and locking up the brakes. Upon inspection, my original brake relay valve had a pin hole in the rubber diaphragm. This was a quick and easy cheap fix. Highly recommended. Thanks very much!

We used this valve to repair brakes on a 1993 Freightliner FL70. It had two valves on the back, and the other vented the air. We replaced another one but the air was still leaking. Eventually we found that this valve had failed and air was escaping to another valve. So we replaced the valve and everything is working again. The ports were positioned differently, but the hardware was the right size and the bracket fitted into the existing holes. We're on the road again!
