Spin-On Breather

Product Overview

Spin-On Breathers protect hydraulic and lubricating reservoirs from airborne particulate using high-efficiency pleated media. The threaded element design installs and replaces with a simple spin-on operation, and a wide range of adapter options means the breather drops into existing reservoir ports without special fittings.
