Great place for Cat parts!
Had some shipping difficulties, but everything was made right. Parts were perfect and an excellent price. Thanks!
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!

Product Questions
Frequently Asked Questions
What is the Caterpillar 8C5230 O-ring seal?
The 8C5230 is a precision O-ring seal used in specific hydraulic, fuel, or lubrication system connections on Caterpillar equipment. It creates a leak-proof barrier at fittings and component interfaces, maintaining system pressure and protecting internal components from fluid loss and contamination.
Which models is the 8C5230 O-ring compatible with?
This O-ring is used across multiple Caterpillar machine families. Always cross-reference the part number with your machine's service manual before ordering. If you are unsure, reach out to Propel Parts for help verifying fitment.
What are the first signs of O-ring degradation I should watch for?
Early signs of O-ring degradation include a slight seepage or weeping of fluid around fittings, a faint fluid smell around the joint area, or staining on components below the sealing point. Catching degradation early allows planned replacement before a complete failure and system fluid loss.
Should I use a pick tool to remove the old O-ring?
Use only plastic or brass picks to remove O-rings from grooves ??? steel picks can scratch the groove surface and create leak paths that a new O-ring cannot seal over. Clean the groove thoroughly after removal to ensure the new O-ring seats perfectly.
Are the O-rings at Propel Parts PTFE coated?
Yes. All Propel Parts O-ring seals are PTFE coated for easier installation, reduced tearing, and extended service life. For a full selection of available sizes and compatible applications, visit our O-ring seals for heavy equipment catalog.
Can I order multiple O-ring sizes together?
Yes ??? Propel Parts allows you to combine multiple part numbers in a single order, which is ideal for planned maintenance programs where several O-ring sizes are needed simultaneously. Same-day shipping on weekday orders ensures fast delivery of everything in your order.
What warranty is included with the 8C5230 O-ring?
A 1-year unlimited mileage warranty covers this O-ring. All Propel Parts components are quality-checked before shipping, and returns are accepted within 30 days.
