Parker 884-2 O-Lube O-Ring Lubricant
by Parker-Hannifin O-Ring Division
Prolongs life of synthetic rubber seals
There are few things on your plane as important, yet overlooked, as O-Rings and seals. While other engine parts may get more attention, without fully intact O-Rings and seals you might as well not have any other engine parts because you aren’t getting off of the ground. Parker O-Lube aircraft lubricant is a barium base petroleum grease formulated to facilitate insulation and extend the service life of synthetic rubber O-Rings and seals.
A thin film of Parker O-Lube applied to the seal itself, as well as the surfaces over which the seal will travel, is recommended for low pressure pneumatic systems as well as reciprocating and low speed rotary or oscillating applications. Well suited for most sealing jobs within a -20°F to +300°F temperature range, Parker O-Lube aircraft lubricant is not recommended for use in systems having micronic filters or in contact with seal materials unsuited for petroleum oil service such as silicone, butyl or ethylene propylene.
