Heater Valve Centering Bushing 26mm — BMW E39 / E38 / E34 / E46 and Mercedes-Benz W140 / W124
Restore Correct Valve Alignment — The Small Part That Makes the Repair Last.
The 26mm centering bushing keeps the heater control valve stem correctly centered in the housing. Without it, or with a worn one, the valve sits off-center — causing uneven seal wear, leaks, and premature failure of a freshly rebuilt valve. Always replace the bushing when rebuilding the valve.
