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.
Product Questions
Frequently Asked Questions
What is the 6F4718 O-ring seal used for?
The 6F4718 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 6F4718 O-ring seal?
To install the 6F4718 properly, prepare the area first and confirm the result afterward. Use these steps:
- 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 6F4718 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 6F4718 compatible with?
The 6F4718 is matched to particular Caterpillar equipment, so always verify the application against your parts reference before purchasing. If you are still unsure, reach out to Propel Parts, our team will be happy to help you verify if this part fits your equipment.
Does the 6F4718 O-ring seal meet performance standards?
Yes. Propel Parts supplies the 6F4718 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 6F4718 be replaced?
Replace the 6F4718 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 6F4718 O-ring seal?
A worn 6F4718 usually gives early warning through the assembly it supports. Watch for these signs:
- 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 6F4718 important, and what related parts work with it?
A sound 6F4718 is inexpensive insurance against larger repairs. Servicing it on time with parts that meet OEM specifications keeps the whole assembly working as intended.
