This ubiquitous fiber washer was used on virtually every BSA and Triumph motorcycle using the external oil pressure relief valve assembly. The washer is responsible for making an oil tight seal between the oil pressure relief valve body and the crankcase threaded port.

Thin fiber washer measures 7/8″ ID x 1-1/8″ OD x 1/32″ thick.

Fitment for:

  • BSA A7, A10, A50, A65, A75, B25, B44, B50
  • Triumph T90, T100, T110, 6T, TR6, T120, T140, T150, T160

The thin fiber washer seals the oil pressure relief valve assembly without affecting the travel of the interior piston.

The washer is placed over the threads of the valve body, which is threaded into the crankcase.
