At the beginning, I experienced significant delays and communication issues regarding my order, which honestly caused serious concern because the parts were urgently needed for an important project.
However, after continuous follow-up, the Propel Parts team handled the matter professionally, provided shipment tracking, and the parts finally arrived successfully.
I especially appreciate their willingness to communicate, acknowledge the issue, and continue working toward resolving the situation.
In international business, delays can sometimes happen, but what matters is the final commitment to resolving the issue properly.
Thank you to Daniel and the team, and hopefully future transactions will be smoother for both sides. -
Above and Beyond
Staff took care of issue that was nit created by them. Package was lost by UPS. Propel sent me another part Next Day Air to correct it. -
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. -
Amazing service, emails answered very quickly with simple straight forward answers. Haven’t received the parts yet but ordering them was quick and easy.

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!
Frequently Asked Questions
What is the 5H6005 O-ring seal used for?
The 5H6005 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 5H6005 O-ring seal?
To install the 5H6005 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 5H6005 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 5H6005 compatible with?
The 5H6005 is matched to particular Caterpillar equipment, so always verify the application against your parts reference before purchasing. Check your manual or reach out to Propel Parts for help verifying fitment.
Does the 5H6005 O-ring seal meet performance standards?
Yes. Propel Parts supplies the 5H6005 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 5H6005 be replaced?
Replace the 5H6005 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. When servicing this area, the 2090633 Seal Gp 6p is commonly replaced at the same time.
What are the signs of a worn or failing 5H6005 O-ring seal?
A worn 5H6005 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 5H6005 O-ring seal important, and what related part is commonly replaced with it?
A sound 5H6005 is inexpensive insurance against larger repairs. Servicing it on time with parts that meet OEM specifications keeps the whole assembly working as intended. During an overhaul, the 1136200 Gasket Exhaust is frequently replaced alongside this part.
