This is a copper valve washer for Becker vacuum pumps. It is made for many U Series models. The valve washer sits inside the pump’s valve system. It helps control the flow of air. It works like a small one-way door. Copper is a soft metal. It creates a tight seal. Over time, these washers can wear out. When they do, the pump loses performance. This is a direct replacement part. Change your valve washers during a rebuild or repair.
Valve Washer, Copper
Valve Washer, Copper
A valve washer is a small, flat disc. It is made of copper. It sits inside the pump’s valve system.The copper material is important. Copper is soft but strong. When the washer presses against its seat, the soft copper squishes a tiny bit. That squishing creates a perfect seal.
These valves open and close many times per minute. They work hard.
Each valve uses a small washer. The washer hits against a metal seat every time the valve closes. Over thousands of hours, that takes a toll.
The washer can get dented. It can get worn down. It can even crack. When that happens, the valve does not seal properly. Air leaks backwards. The pump cannot make good vacuum.
