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
Customer service was excellent today! I have never had a company go behind the scenes to see what was happening with my payment error and resolve it so I could complete my order without having to do it all over again. Hats off to Propel Parts!

Product Questions
Frequently Asked Questions
What is the Caterpillar 0951590 Seal O‑Ring used for?
The 0951590 Seal O‑Ring is a sealing component designed to prevent fluid or air leaks in systems of Caterpillar heavy machinery. It's typically used in hydraulic, transmission, or engine assemblies where a tight, reliable seal is essential to maintain pressure and protect internal parts.
Will this O‑Ring fit my Caterpillar equipment?
Yes this aftermarket Seal O‑Ring is engineered to the same U.S. OEM specifications as the original Caterpillar part number 095‑1590, and Propel Parts performs fit verification using Caterpillar's Service Information System (CAT SIS) to ensure a correct match before shipping.
Is this an OEM part or aftermarket replacement?
This Seal O‑Ring is an aftermarket replacement built to meet Caterpillar OEM specs for durability and performance. Although not shipped directly by Caterpillar, it's manufactured and tested to fit and seal like the original part.
What quality standards does this O‑Ring meet?
The 0951590 meets OEM performance standards and is built to handle the same demanding conditions as the original. Need help confirming compatibility? The Propel Parts team can help identify the correct fit for your application.
How do I know when to replace this seal?
O‑Rings can wear over time due to pressure changes, temperature extremes, or fluid contamination. If you notice leaks, low system pressure, or routine maintenance calls for it, replacing the seal can help prevent bigger issues. Regular inspection helps catch wear before failure.
Does this part come with a warranty?
Yes this O‑Ring includes a 1‑year warranty from Propel Parts, providing protection against manufacturing defects. Combined with their Exact Fit Guarantee®, you can replace your part with confidence.
How small is this Seal O‑Ring and what should I expect in terms of size?
For precise 0951590 dimensions, refer to the specification details on the product listing or cross-reference with your equipment manual. The Propel Parts team can also help confirm the correct size if needed.
