Small Filler Cap & Bung

The Neil & Parks Small Filler Caps are perfect for valve covers, rear end housings and other tanks. The very light weight design has large threads, much easier to screw in without crossthreading, and features a captive O-ring that won't fall out for a excellant seal. Caps feature black hard anodizing to prevent corrosion and a knurled grip.

The bung which is available in either steel or aluminum has 1 5/16" threads and 1 1/4" ID, please specify material choice when ordering.

Sold as a cap and bung assembly.
