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

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!
