Hydraulic Filter — Spin-On 1-1/8-16, 3.66×5.35 in SKU: QT57998

This spin-on hydraulic filter keeps return and charge oil clean to protect pumps, valves, and wet brakes during heavy fieldwork. It’s a service-friendly element sized for a tight, reliable seal and steady flow in demanding farm conditions.

The canister design seats squarely on the head and stands up to vibration and pressure ripple from loaders, remotes, and hitch operation. Replacing a restricted element on schedule helps reduce heat, chatter, and premature component wear.
