Seal in groove (1) SealRadial sealing depends upon proper seating of the seal in the groove and maintaining this condition during assembly of the joint. Improper assembly practices increase the likelihood of leaking joints. An example of a radial O-ring application is shown in Illustration 33. This document addresses both Seal-in-Bore (Housing) (Illustration 34), and Seal-in-Piston (Shaft) (Illustration 35) designs.Handling
O-rings should not be stretched or twisted beyond what is necessary for installation. O-rings should not be deformed in any manner.Contact of the O-ring with threads or other sharp objects should be prevented as the contact risks cutting, nicking, or damaging the seal.Assembly Aids - Seal Lubricants
When O-rings and other elastomeric seals are assembled into radial seal joints, a lubricant is necessary to reduce spiraling, skiving, cutting, and abrasion. Lubricants also reduce the force required to assemble the joint.Lubricants shall be stored in properly identified, clean, closable containers that are kept closed between uses. Consult the Contamination Control Guidelines, PEBJ0002, "Caterpillar Dealer Contamination Control Compliance Guide".Do not use petroleum (Vaseline), any adhesive, or unapproved grease as a lubricant.Lubricants shall not be used on PTFE coated seals or STOR/ORFS seals.Assembly Aid - Approved Seal Lubricants
PTFE Coating
PTFE coating is a dry lubricant that should be used on all radial seals. The PTFE coating is added by the manufacturer.P-80
P-80 may be used as a universal seal lubricant. P-80 is compatible with all sealing elastomers. P-80 dries quickly so P-80 is unlikely to drip out and create the false appearance of a fluid leak.P-80 must NOT be used on STOR/ORFS seals. P-80 or any other lubricant used on a STOR/ORFS can affect final torque and cause thread stretching.The use of P-80 on all other PTFE coated seals is acceptable.Fluid Being Sealed
For oil and fuel joints, the fluid being sealed may be used as a lubricant.Note: Lubricants must not be used on fluid line connectors (STOR/ORFS) fittings.Low Pressure AC Line Lubricants
For low-pressure air conditioner lines use the following approved lubricant:Mineral Seal Oil - McMaster Carr Part No. 3190K281Lubricant Dispensers

Spray bottleThe recommended method for applying a lubricant is with a small nozzle spray bottle (Illustration 36).Dispose of lubricant containers that have become internally contaminated.Lubricant Application
Lubricants are low viscosity fluids that shall be used only on radial seal joints.Seal lubricant shall always be applied to the primary sealing surface. For example, if the seal is in a groove in the shaft, then the bore is the primary sealing surface. Optionally, lubricant may also be applied to the seal.Apply wet lubricants at the time of assembly. Do not apply the lubricant in advance.The application of lubricants shall not introduce debris onto the seal or sealing surface.Do not apply seal lubricants with brushes or fingers, which can introduce contamination into the system. Avoid the use of brushes that shed fibers.When using lubricant dispensers such as spray bottles, exercise extreme caution and prevent overspray onto other areas, such as threads, as it may have an adverse effect on torque. Cover all components that must not be lubricated
