A Delay Handled the Right Way
Honestly, if I were in Miami like my shipment was, I wouldn?t have been in a hurry to ship out either. I was frustrated at first ? delays cost me time on the job ? but Propel Parts stepped up.
Deb, Daniel and the team owned the mistake, kept the communication clear, and graciously refunded my shipping costs without making it a hassle. That kind of accountability is rare these days, and I genuinely appreciated how they handled it.
Things don?t always go perfectly, but these folks proved they?re more interested in doing right by their customers than just pushing parts out the door. Solid company, solid people.

P.S. Incredible quality on the pin as well. I had to do some custom modifying, and let?s just say the case hardening was ? well ? hard. Great Stuff! Thank you.
Everything fine, thank you. The only thing with which I had a problem in your Software, is that when I have more than 10 different items on the list, I can't scroll to the first ones. But besides that, I am very happy in going on with buying your parts.
Amazing Help.
I don't know who I spoke with, but they were helpful. We will be buying those parts shortly.

English Translation
If you need affordable replacement parts for your heavy equipment and want attentive customer service, this store is a very good option.
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 9P6798 ring seal used for?
The Caterpillar 9P6798 ring seal is a precision sealing component designed to create a secure, leak‑resistant barrier between mating parts in Caterpillar engines, transmissions, or hydraulic systems. It helps prevent loss of oil, coolant, or hydraulic fluid and keeps contaminants out of critical systems.
Which Caterpillar machines commonly use the 9P6798 ring seal?
Compatibility of the 9P6798 can differ depending on the machine model and serial number. Verify fitment in your service manual before purchasing, or reach out to Propel Parts — our team can quickly confirm the right part for your equipment.
What does a ring seal do in heavy equipment systems?
A ring seal such as the 9P6798 provides a tight, fluid‑resistant seal between two surfaces. It helps maintain proper pressure, protects against leaks, and prevents dirt, dust, and debris from entering fluid systems. This is essential for smooth operation and long‑term reliability in engines and hydraulic systems.
Is the 9P6798 ring seal an OEM or aftermarket replacement part?
Aftermarket, but built to OEM standards — the 9P6798 offers the same fit and performance as the original part. Contact Propel Parts if you need help verifying compatibility with your equipment.
How do I install the 9P6798 ring seal correctly?
To install the 9P6798 ring seal properly:
- Clean both sealing surfaces to remove old material, dirt, and oil.
- Position the ring seal evenly in the groove or housing.
- Make sure the seal isn't twisted or pinched.
- Reassemble the components and torque fasteners to the manufacturer's
> recommended specifications. Proper installation helps maintain efficient sealing and prevents fluid leaks.
What are signs that a ring seal like 9P6798 needs replacement?
Common signs include:
- Oil, coolant, or hydraulic fluid leakage around joints or housings
- Loss of system pressure
- Contaminated fluid
- Unusual noise or rising temperatures due to fluid loss
Identifying these symptoms early and replacing the ring seal can help prevent larger equipment issues.
Why is using the correct ring seal important for Caterpillar equipment?
Every component in heavy equipment operates within specific tolerances. Using the correct 9P6798 ensures those tolerances are maintained, protecting the system from leaks, wear, and unexpected failures.
