Granatelli Motor Sports Press-In PCV Breather 451001

The Granatelli Motor Sports screw in baffle kit is perfect for installing a 1” diameter press in breather system into your valve covers without requiring welding. They are designed for use on valve covers that do not have breather holes or when an extra one is required in a different location. The 451001 kit features a 1 in. double O-ring I.D. female receptacle for use with most push-in breathers and the supplied mushroom style unit included. They are baffled to prevent unwanted oil from pushing out of the breather. The baffle requires an appropriately sized 1.375” hole be drilled into the cover and includes a lock nut, sealing washer, O-ring, and threaded baffle.
