Caterpillar Standard Efficiency Hydraulic Filter | Part 126-2081

Product Overview

Using genuine-spec filters ensures consistent oil flow and maintains the integrity of the hydraulic system during heavy-duty operations.

This filter is a precise fit for a broad range of Caterpillar B-Series and C-Series excavators, including the 311B, 315B, 318B, 320B, 322B, 345B, and 365B models mentioned. It is also used in various wheeled excavators and forest products machinery. It can be cross-referenced with several major brands, including Baldwin PT8436, Donaldson P550577, Fleetguard HF35195, and Wix 57244.
