KOOTANSEmergency Glad Hands with Valve Set Aluminum Gladhand Handshake Kit Universal Air Hose Brake Coupling Connector with Anodized Aluminum Handles, for Truck Semi Trailer Tractor RVS

The aluminum colored handles did not fit the threads of either glad hand. (The glad hands without the valves looked like they were supposed to thread on, but trying to thread the handles on just stripped the threading on the handles and left aluminum slag in the glad hand.) The glad hands with the valves did not fit the trailer I wanted to use this with: there was no way to get them on where the valve handle was not interfering with the attempt to connect.Recommend avoiding this product.

The service side glad hand had a bad valve. I assume it has a ball valve that is spinning free from the valve handle. At times air flows no matter which way the handle is turn. It will also suddenly stop air flow no matter which way the handle is turned. Absolutely useless! However the standard glad hands and extensions are fine.

These are very poor quality and will not work!! The valves allow air to leak passed when closed!!These will not allow safe use of a trailer brake system. DO NOT BUY THESE!!

These appear to be made from good materials and seem to be very well made.

Good
