5J8156 Snap-in Wiper Seal for Caterpillar Equipment

The 5J8156 snap-in wiper seal is a rod wiper seal used in Caterpillar equipment hydraulic applications. It is designed to help prevent external contaminants from entering the system and is intended for applications with less severe operating conditions and lower hydraulic pressure than applications using a pressed-in wiper seal. This is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).

The seal has a snap-in installation form and is identified as a REG-type seal. The supplied part is the wiper seal only; no additional components or installation hardware are specified in the available product data.
