Baldwin BT334 Hydraulic Oil Filter

The Baldwin BT334 is a spin-on hydraulic and lubrication filter designed for automotive fluid systems. It carries a 9.8 micron rating to capture fine contaminants and protect downstream components. The unit includes an integrated gasket for a reliable seal. It suits maintenance crews and equipment operators who need consistent filtration performance.

Installation Notes

The filter uses a 1-1/8 inch thread size and measures 5 3/8 inches in length with a 3 11/16 inch outside diameter. Spin the canister onto the mounting base by hand until the gasket contacts the surface, then tighten the recommended additional turn. Ensure the mating surface is clean and the old gasket is fully removed to prevent leaks. Over-tightening can damage threads or distort the sealing surface.

Fitment Guidance

This filter fits hydraulic and lube circuits that accept the specified thread, dimensions and micron rating. It is not suited for applications requiring a different thread pitch, a finer or coarser micron rating, or a cartridge-style housing. Buyers needing a different flow capacity or a non-spin-on design should verify their equipment specifications before ordering.
