Lubrication

When assembling Type CH O-Rings with O-Ring style fittings, the O-Ring shall be coated with the fluid used or petrolatum before assembly to ease installation.

When assembling Type CA O-Rings with O-Ring style fittings, lubricate the O-Ring with the fluid used in the system.  Do not use a petroleum-based lubricant.

When assembling Type HK O-Rings with O-Ring style fittings, the O-Ring shall be coated with the fluid used or petrolatum before assembly to ease installation.
