Q:

How much do I need to tighten a fill cap?

A:

It is not necessary to bottom the fill cap into the receiving bung. Adequately seating the O-ring to make a seal is all that is required. The radial squeeze action on the O-ring creates a strong seal and helps to keep the cap from coming loose.

 



Q:

What should I use to lubricate a Buna O-ring?

A:

A light coating of Dielectric grease works very well as O-ring lubricant.

 



Q:

What is Buna and is it compatible with my fluid?

A:

Buna is a universal composition synthetic rubber, a standard of plumbing related products because it is compatible with many fluids. Due to the complex chemistry of modern day performance oils and fuels, you may find it necessary to replace Buna components with a material that is compatible with the unique chemistry of your specific fluids.
