Busch Exhaust Valve, Viton Part# 916126769 – vacstellar

This Busch exhaust valve is the perfect solution. It is an exact replacement for your old, worn-out valve.

The key to its performance is the Viton seal. Viton is a special material that can handle tough conditions. Inside the pump, the exhaust valve gets hot and is exposed to oil mist.

A standard rubber seal can harden and crack. But the Viton seal stays flexible and strong. It creates a perfect seal every time the pump cycles.

This means quieter operation and consistent vacuum power. Your pump will work the way it was designed to.

This part is compatible with popular Busch pumps like the R5, Panda, and Samos series. Installing the correct valve restores your pump’s health and performance.
