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. Contact with threads 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 should be stored in properly identified, clean, closable containers that are kept closed between uses. Refer to PEBJ0002 for further information.Do not use petroleum (Vaseline®), any adhesive, or unapproved grease as a lubricant.Lubricants should 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 making the lubricant 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 McMaster Carr 3190K281 approved lubricant.Lubricant Dispensers

Spray Bottle
The recommended method for applying a lubricant is with a small nozzle spray bottle.Note: Dispose of lubricant containers that have become internally contaminated.Lubricant Application
Lubricants are low viscosity fluids that should be used only on radial seal joints.Seal lubricant should 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 should not introduce debris onto the seal or sealing surface.Do not apply seal lubricants with brushes or fingers. This action may 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. Overspray can have an adverse effect on torque. Cover all components that must not be lubricated before lubricating. Refer to PEBJ0002.Before using P-80 lubricant, shake well to ensure proper mixing of lubricant.Apply lubricants only at the time of assembly. Lubricants, especially P-80, may dry up or leak out of the joint if applied in advance.For low-pressure air conditioner lines, lubricate the O-ring with the mineral oil.Tooling Inspection
Inspect tooling before use for contamination and damage in the form of nicks, gouges, or missing material.Improperly maintained
