SEAL-PISTON (CAT CT3016170005)

A worn piston seal can allow fluid bypass, reducing system pressure and causing sluggish movement. This aftermarket replacement part references CAT as the OE maker and cross-references part number CT3016170005. The seal type is a piston seal, which creates a barrier between moving and stationary surfaces inside a cylinder. Its plain mechanical function is to contain pressurized fluid while permitting the piston to slide. A generic failure consequence is that a degraded seal leads to internal leakage and loss of force. Keeping a piston seal in sound condition helps maintain consistent actuation and prevent contamination. Verify the serial number or application, then call (562) 693-7748.
