Thin Wall, Fixed Body Viton Valve Seals

Positive Valve Seals, Universal Fit- Set of sixteen.

11/32" X .530"/.531" (see note at bottom of this page)

These are from our fixed body, thin wall valve seal family. Metal clad with a small garter spring for consistent oil control.

Intended for applications where additional clearance is required between the seal body and inner valve spring. Normally used on race heads with triple valve springs. For street applications with .530" guides, use valve seal # VSS-284 instead.

     Common Applications for this seal:

• Race heads with 11/32" valve stems and guides no smaller than .530", use for valve springs which have a very small inner spring diameter and need maximum clearance between the seal and inner valve spring.
  

Note: Thin wall seals do not tolerate undersize valve guides. The seal provision portion of the valve guide needs to be no smaller than .530" otherwise the seal will not stay put, it will come off. Verify your guide diameter in advance of purchase. Guides measuring .527"-.529" should use VSS-275 instead.
