Very nice job
Good Stuff.
We have had a couple shipping issues, but each time they made it right and we ended up getting what we need. Quality parts at half the price of OEM.
I would give 5 stars but my first time ordering from here and using aftermarket parts. The price is reasonable comparing to original Cat parts and the customer support is great and hoping to do more business with them

Product Questions
Frequently Asked Questions
What is the Caterpillar O-Ring 2147567 used for?
The 2147567 O-Ring is a precision sealing component used in Caterpillar hydraulic systems, engine assemblies, and fluid line connections. O-rings create a radial or face seal that prevents fluid leakage under pressure. This particular part is used wherever the specific cross-section and diameter specifications match an application in your CAT equipment.
How do I know if an O-ring needs replacement?
Replace O-rings when you notice visible fluid weeping or dripping at a sealed connection, dry rot or cracking on the ring surface, flattening or compression set that reduces sealing force, or any time a joint or fitting is disassembled. It is good practice to never reuse O-rings once they have been removed.
What material is the 2147567 O-Ring made from?
Caterpillar O-rings are typically made from nitrile (NBR), fluoroelastomer (Viton), or polyurethane depending on the fluid type and operating temperature. The 2147567 is manufactured to meet or exceed OEM material specifications for the application it serves in CAT equipment.
Is this part compatible with both hydraulic and engine applications?
O-rings are application-specific by size and material. The 2147567 is sized and specified for the exact fitting or joint it was designed for in Caterpillar equipment. Always confirm the part number matches your application rather than substituting by size alone. If you need help confirming compatibility, reach out to Propel Parts.
What lubricant should I use when installing the 2147567 O-Ring?
Use the appropriate system-compatible lubricant ??? for hydraulic applications, use a small amount of clean hydraulic fluid; for fuel system applications, use clean diesel. Never use petroleum-based grease on O-rings that will be in contact with hydraulic oil unless specified, as it can swell certain elastomers.
Can I buy O-rings in bulk for a maintenance kit?
Absolutely. If you service multiple machines or need a range of sealing components, Propel Parts offers an extensive selection of O-ring seals for heavy equipment in various sizes and materials ??? making it easy to stock your service truck or shop for efficient, on-the-spot repairs.
Does Propel Parts carry other seal types beyond O-rings?
Yes. In addition to O-rings, Propel Parts stocks oil seals, metal face seals, lip seals, crankshaft seals, and complete gasket kits for Caterpillar equipment. Use the part number from your service manual to quickly locate the correct seal for your application.
