EXCERPT:
Background
Commonly used fluid line connectors are: Straight Threaded
1. O-Rings (STOR)
2. O-ring Face Seal (ORFS)
3. Bolt Flanges (SAE Code 61, 62, and CAT Flange)
Radial O-ring seals and conventional face seals are not fluid line connectors.
O-ring sealing depends on proper seating of the seal in the groove, maintaining this condition during assembly of the joint, and proper torque on the connection. Improper assembly practices increase the likelihood of leaking joints.
Assembly Aids - Retention compounds and lubricants must not be used on STOR/ORFS.
Applications requiring the use of a retention compound need to be validated for seal compatibility with the retention compound by Caterpillar before use.
Assembly Tooling
O-rings may be installed into a fitting/adapter without the use of a tool however, installing a seal without the use of a tool places the seal at extreme risk of damage. It is recommended that appropriate tooling should be used for the installation of O-rings.
Types of Installation Tooling

(6) ORFS O-ring
When installing an O-ring over a threaded fitting, it is critical to protect the seal from damage from threads. To assist the assembly and protect the seal, an installation tool must be used shown in Illustration 2. The seal protector slides over the threads and allows for an O-ring to be installed, reducing the risk of a leak due to nicks, cuts, gouges, and twisting of the seal.
