Great customer service answered email question quickly.
Great pricing and fast shipping!
I'll admit that I was skeptical of propel parts, but they are an honest site and came through with the order. I was skeptical because I've never ordered heavy machinery parts, and didn't know who to trust. The parts that I ordered showed in stock, but after checking with their vendor, they only had half of the order in stock. I was notified the day after the order, and most of the parts arrived in a few days. There was one part that was not shipped putz but I was able to talk with who I assumed is the owner who rectified the situation and had the part overnighted to me.
I will say that communication speed could use a little work, but they will eventually get back with you.
I own old cat bulldozers D8k,D8H,D8N that required frequent repairs and servicing. it was erratic and practically cumbersome to keep them running without constant supply of reliable
and affordable spares in Uganda a third world country however,since I started dealing with propel parts US,my bulldozers have earned reliability and efficiency in providing high quality services to clients and making me a great dependable construction company in earth moving.
My shipments are always handled expeditiously and delivered in record time to Uganda this is awesome from Propelparts.
My business is booming by the clock for finding the best partner in Propelparts.
Great service at an affordable price to get my machine back going.

Product Questions
Frequently Asked Questions
What is the Caterpillar 2H3088 seal O-ring used for?
The 2H3088 seal O-ring is designed to create a tight seal between connected components in Caterpillar equipment. It helps prevent the leakage of oil, fuel, or hydraulic fluids while keeping dirt and contaminants out of the system. A properly functioning O-ring supports stable system pressure and contributes to reliable machine operation.
Which Caterpillar equipment may use the 2H3088 seal O-ring?
Always cross-reference the 2H3088 part number against your equipment manual before purchasing, as configurations can differ across serial number ranges. Not sure? The Propel Parts team is happy to confirm the right fit for your machine.
What are the signs that a Caterpillar seal O-ring needs replacement?
A worn or failing 2H3088 seal O-ring can lead to sealing problems that affect equipment performance. Common signs include:
- Oil, fuel, or hydraulic fluid leaks around the sealed area
- Loss of pressure within the system
- Visible cracking, flattening, or deformation of the O-ring
- Contaminants entering the sealed component
Replacing a damaged O-ring promptly helps prevent further system damage and costly downtime.
Does the 2H3088 seal O-ring meet performance standards?
Yes — the 2H3088 replacement is engineered to OEM standards, so you can count on dependable performance in heavy-duty conditions. If you have questions about fitment or compatibility, the Propel Parts team is ready to assist.
How do you install the 2H3088 seal O-ring?
Correct installation helps maintain proper sealing performance. Typical installation steps include:
- Turn off the equipment and release system pressure
- Disassemble the component containing the O-ring
- Carefully remove the worn or damaged O-ring
- Clean the sealing groove and surrounding surfaces
- Install the new 2H3088 O-ring properly in the groove
- Reassemble the components and check for leaks
Always refer to the equipment service manual for the exact installation procedure.
How often should the 2H3088 seal O-ring be replaced?
Seal O-rings generally do not have a fixed replacement interval, but they should be inspected during routine maintenance or whenever a component is disassembled. If there are signs of wear, cracking, or leakage, replacing the 2H3088 seal O-ring can help maintain system pressure and prevent equipment failures.
Can I use a premium aftermarket 2H3088 seal O-ring replacement?
Yes — high-quality aftermarket 2H3088 replacements are widely used and can deliver the same performance as original parts when manufactured to OEM specifications. A reliable replacement keeps the system protected and equipment running as expected.
