Great customer service.
Prompt , knowledgeable and friendly service.
Have been buying parts from them for years, and they have always delivered, both with parts and customer service.
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!

I recently had to cancel an order with Propel Parts, and I was thoroughly impressed by the prompt and efficient service I received. Steven handled my request with professionalism and speed, ensuring a hassle-free process. I've purchased parts from Propel Parts before and have never been disappointed. Their consistent reliability and excellent customer service keep me coming back.
He was a great help with ordering and refunding the sales tax,
Product Questions
Frequently Asked Questions
What is the 6F6672 O-ring seal used for?
The 6F6672 O-ring seal sits in a groove and is compressed between two surfaces to block fluid or air leakage. Its elasticity is what creates a tight, reliable seal.
How do I install the 6F6672 O-ring seal?
A reliable installation of the 6F6672 starts with inspection and ends with verification. Follow this process:
- Depressurize the system and shut the machine down before service
- Remove the old O-ring and clean the groove thoroughly
- Inspect the groove and mating face for nicks or debris
- Lubricate the 6F6672 as directed and seat it evenly in the groove
- Reassemble carefully so the O-ring isn't pinched, then check for leaks
Which Caterpillar machines is the 6F6672 compatible with?
The 6F6672 is matched to particular Caterpillar equipment, so always verify the application against your parts reference before purchasing. Please reach out to Propel Parts for help verifying fitment.
Does the 6F6672 O-ring seal meet performance standards?
Yes. Propel Parts supplies the 6F6672 as a premium aftermarket part made to meet OEM specifications. When replacing, choose genuine or high-quality aftermarket parts that meet or exceed OEM specifications so you can fit it with confidence.
How often should the 6F6672 be replaced?
Replace the 6F6672 whenever the assembly it serves is overhauled, or any time it shows wear, damage, or corrosion. Following the intervals in your service manual is the best guide.
What are the signs of a worn or failing 6F6672 O-ring seal?
Catching a failing 6F6672 early prevents wider damage. The common warning signs include:
- Leaks or weeping at the sealed connection
- A flattened, nicked, or hardened ring on removal
- Loss of pressure in the circuit
- Swelling or extrusion from the groove
Why is the 6F6672 important, and what related parts work with it?
Keeping the 6F6672 in good condition protects the components around it and supports smooth, reliable operation. Maintaining the assembly with parts that meet OEM specifications helps you avoid unplanned downtime. Related hardware on our site includes 1352651 Seal Press Rlf and 9L8020 Gasket.
