Overall Assessment

Customers praise the product for its perfect fit and practicality, particularly in car restorations and adjustments, such as for a '56 Mercury, a '37 Ford Coupe, and a '72 Chevy with an SBC350 engine. Many used it for valve and breather installations stating it fits various components like Spectre Cran case filters and PVC valves. Users commend the product's material quality for not leaking while highlighting it's ideal for thicker, not stamped steel, valve covers. The product's usability is also highly rated, often recommended as a reliable, hard-to-find part that completes jobs smoothly.

Fit perfectly

This is the correct size for my chrome aluminum valve covers. And the correct i.d. for my PCV valve. This was on my 1972 chevy c10 with SBC350. This grommet has the wider groove for the thicker valve covers. WILL NOT WORK FOR STAMPED STEEL VALVE COVERS. Just to let ya know. :)

I put it in a valley pan on a 312 y block engine. Now the engine has a pvc valve. Service was excellent I drove 82 miles around trip to pick up a 4 dollar part. Shipping would have been cheaper.
