Excavator Couplings

Caterpillar Excavator Hydraulic Couplings for Enhanced Equipment Performance

Caterpillar excavator hydraulic couplings are engineered to deliver reliable, leak-free connections for your machine’s hydraulic systems. Built from high-quality thermoplastic polyester and high-temperature rubber (HTR), these couplings excel at resisting extreme temperatures, harsh chemicals, and solvents ensuring dependable performance even in the most demanding construction and industrial environments. Their advanced materials absorb shock, reduce wear, and minimize vibration, resulting in longer equipment life and less downtime.

Available in a range of sizes to fit models like CTP30H, CTP50H, CTP110H, CTP140H, and CTP160H, each coupling is designed for a precise match to your Caterpillar equipment. Regular inspection and replacement of worn couplings help prevent hydraulic leaks, maintain system pressure, and protect against costly component failure.

Propel Parts makes it easy to find the right excavator hydraulic coupling for your machine, with clear part listings, expert support, and fast shipping to keep your equipment running smoothly. Our Excavator Coupling (Hydraulic System) assemblies are manufactured with the highest quality thermoplastic polyester as well as high temperature rubber (HTR), that are highly resistant to extreme temperatures, chemicals and solvents. Both materials have excellent properties for transferring and absorbing shock load and reducing wear on equipment.
