Customer Reviews
Steven & Propel Parts were a huge help! We were able to place a large order and get it shipped out same day to avoid a line down situation for a customer due to a lost component. The order was even submitted after the 3pm cutoff for same day shipments and we got it the next morning!
When I had questions, they were answered quickly and kindly.
Thank you!!
Excellent customer service and parts.
You guys have always gave excellent customer service!!! Very prompt responsiveness. Warranty services are superb. I have been using them for quite awhile now on equipment I have. Always great prices for parts! Keep up the great work guy's
Been buying from them for years and have almost never had an issue. The few times I had a question or something to handle, they have shown amazing customer service. Great product and a great company.
I almost want to cry ;( writing this review because I dont want people to find out about them and rather keep them in my pocket but they deserve it…
This company is great with Quality Products at amazing prices! Sometimes, their website is not the most accurate but is user friendly and if you got questions they will call back and are very prompt in responding via a call or text to verify inventory before placing an order.
I really appreciate and look forward to continuing to work with you all especially Anthony — he is amazing & the best!!!
Amazing Help.
I don't know who I spoke with, but they were helpful. We will be buying those parts shortly.

Product Questions
Frequently Asked Questions
What is the 8H9180 seal used for?
The 8H9180 is a sealing component that blocks fluid leakage and keeps dirt and debris out of the assembly. Reliable sealing is key to maintaining pressure and protecting internal parts.
How do I install the 8H9180 seal?
To install the 8H9180 properly, prepare the area first and confirm the result afterward. Use these steps:
- Shut down and depressurize the system, then let it cool if needed
- Remove the old seal and clean the bore and shaft surfaces
- Inspect the sealing surface for scoring, pitting, or wear
- Lightly lubricate the 8H9180 as directed and fit it square to the bore
- Seat it to the correct depth without distorting the lip, then check for leaks
Which Caterpillar machines is the 8H9180 compatible with?
Compatibility for the 8H9180 seal varies by machine and configuration, so cross-check it for your Caterpillar equipment before ordering. Or reach out to Propel Parts for help verifying fitment.
Does the 8H9180 seal meet performance standards?
Yes. The 8H9180 is engineered to meet OEM specifications for material, dimensions, and durability. When replacing, choose genuine or high-quality aftermarket parts that meet or exceed OEM specifications so the part performs the way it was designed to.
How often should the 8H9180 be replaced?
The 8H9180 is typically renewed during scheduled service or a related repair. In demanding, high-hour operation, inspect it more often to stay ahead of wear.
What are the signs of a worn or failing 8H9180 seal?
A worn 8H9180 usually gives early warning through the assembly it supports. Watch for these signs:
- Visible fluid leaks or seepage at the joint
- Loss of system pressure
- Contamination found inside the assembly
- A hardened, cracked, or torn sealing surface
Why is the 8H9180 important, and what related parts work with it?
A sound 8H9180 is inexpensive insurance against larger repairs. Servicing it on time with parts that meet OEM specifications keeps the whole assembly working as intended. Related hardware on our site includes 3107257 Seal O-Ring and 2N0931 Gasket Ctp.
