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 most fluids. Buna components may need to be replaced by a material compatible with the specific chemistry of some fluids. |
