Very helpful. Every question or request I had was answered quickly. I didn't have a parts book for my excavator but that was no problem for them. If you need parts for your Cat, give them a shot.

Online order.
I had a good experience this morning I placed an online order and everything went smoothly. The staff at propel parts has always been helpful in the past when I have been looking for harder to find parts or something that wasn’t listed online.
Frequently Asked Questions
What is the Caterpillar 0951586 O-ring seal used for?
A: The 0951586 O-ring is used to create a tight seal in hydraulic, fuel, and engine system connections on Caterpillar equipment. It prevents fluid leaks and maintains pressure integrity across the system.
Is the 0951586 O-ring compatible with my machine?
A: This O-ring is engineered for specific Caterpillar applications. Please check your parts manual or reach out to Propel Parts for help verifying fitment with your equipment.
When should I replace the 0951586 O-ring?
A: Replace it whenever you see fluid seeping from a sealed connection, when the existing ring appears cracked or deformed, or routinely whenever you disassemble the joint it seals. Replacing O-rings proactively during service is a best practice.
Is this a high-quality aftermarket O-ring?
A: Yes. This is a premium high-quality aftermarket O-ring that meets or exceeds OEM specifications for material composition, dimensions, and performance. It provides a reliable and cost-effective replacement for the original part.
For a wide variety of sealing components, visit our seals and gaskets category.
What material is used in the 0951586 O-ring?
A: This O-ring is manufactured from high-grade elastomeric material resistant to hydraulic oil, diesel fuel, coolant, and temperature extremes typical in heavy equipment. It also features a PTFE dry-film coating for easier installation and longer service life.
Can I use any lubricant during O-ring installation?
A: Use only system-compatible fluids (such as hydraulic oil or engine oil) to lightly lubricate the O-ring before installation. Avoid petroleum-based greases on EPDM or silicone O-rings as they can cause swelling and seal failure.
Does Propel Parts offer a warranty on this O-ring?
A: Yes. All products from Propel Parts include a 12-month warranty against manufacturing and material defects. Same-day shipping is available for weekday orders placed by 3pm ET.
