Everything fine, thank you. The only thing with which I had a problem in your Software, is that when I have more than 10 different items on the list, I can't scroll to the first ones. But besides that, I am very happy in going on with buying your parts.

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!!!
Frequently Asked Questions
What is the Caterpillar 4C4784 D-ring seal kit used for?
A: The 4C4784 D-ring seal kit is used to seal hydraulic connections in Caterpillar equipment. D-ring seals (also called boss seals) provide a reliable leak-proof connection at O-ring boss fittings in hydraulic systems, preventing fluid loss and contamination.
What is included in the 4C4784 D-ring seal kit?
A: This kit typically includes the D-ring seal and backup ring designed for use with specific Caterpillar O-ring boss (ORB) fittings. Check the product listing for complete contents or contact Propel Parts for details.
How do I know when D-ring seals need replacement?
A: Replace D-ring seals when you observe hydraulic fluid leaking at fitting connections, any disassembly of the fitting for service, or visible damage or hardening of the existing seal. D-ring seals are inexpensive insurance against hydraulic leaks.
Is this a high-quality aftermarket seal kit?
A: Yes. This is a premium high-quality aftermarket D-ring seal kit that meets or exceeds OEM specifications for material composition, dimensions, and pressure rating.

Which CAT machines is the 4C4784 seal kit compatible with?
A: This seal kit is used across a range of Caterpillar hydraulic systems. Check your parts manual or reach out to Propel Parts for help verifying fitment with your machine.
How do I install a D-ring seal correctly?
A: Clean the fitting and boss threads thoroughly. Apply a light coat of clean hydraulic fluid to the D-ring. Install the seal into the boss groove, then thread the fitting in by hand before torquing to the specification in your Caterpillar service documentation.
What warranty is included?
A: All Propel Parts products include a 12-month warranty from the invoice date against manufacturing and material defects. Same-day shipping is available on weekday orders placed by 3pm ET.
