Product Questions
Frequently Asked Questions
What is the 1142687 O-ring seal used for?
The 1142687 is an O-ring style seal used to prevent leaks at a joint or connection. Correct sizing and material let it hold pressure without hardening or extruding.
How do I install the 1142687 O-ring seal?
A reliable installation of the 1142687 starts with inspection and ends with verification. Follow this process:
- Depressurize the system and shut the machine down before service
- Remove the old O-ring and clean the groove thoroughly
- Inspect the groove and mating face for nicks or debris
- Lubricate the 1142687 as directed and seat it evenly in the groove
- Reassemble carefully so the O-ring isn't pinched, then check for leaks
Which Caterpillar machines is the 1142687 compatible with?
