Description
Duco® genuine replacement parts are manufactured to the same quality standards as the components originally installed in your equipment.
The U38977-RK is a commercial-grade stem and disc repair kit designed to effectively eliminate leaks in air vacuum valves on Unipress pressing machines. Over time, internal parts can wear out, preventing the valve from fully sealing under air pressure. This kit restores proper operation without replacing the entire valve. It includes a stainless steel spring and PTFE gasket for enhanced durability, extended service life, and reliable performance.
