Customer Comments: "I use your bolt on caps and bungs on my carbon fiber Cummins common rail valve covers. Love the quality. Thank you." – Randy Davis, Owner of OldSkoolFab, Inc. "I upgraded my fuel cell to an Easy Turn fill cap assembly. It wasn't long until all my friends did the same. Great product!" – As shared with us at the PRI Show Frequently Asked Questions Q: How much do I need to tighten a fill cap? A: It is not necessary to bottom the fill cap into the bung−just adequately seat the O-ring. The radial squeeze action on the O-ring creates a positive seal and helps prevent the cap from coming loose. Q: What should I use to lubricate the Buna O-ring? A: Applied periodically, a light coating of Dielectric grease has proven to work well as an O-ring lubricant. Q: Is Buna rubber compatible with my fluid? A: Buna is a synthetic rubber compound suitable for use with many fluids. Buna components may need to be replaced by a material compatible with the specific chemistry of some fluids.
