Donaldson P561131 Hydraulic Head Assembly

Product Overview

The Donaldson P561131 Hydraulic Head Assembly is a genuine Donaldson filter head designed for use with SP15/25 Series spin-on hydraulic filters. It provides a secure mounting point for the filter while directing hydraulic fluid through the filtration system to protect pumps, valves, cylinders, and other critical hydraulic components.

Engineered for low-pressure hydraulic applications, the P561131 features 3/4-14 NPT inlet and outlet ports, an integrated 25 psi (1.7 bar) bypass valve, and 1-12 UN filter mounting threads. Its durable construction and compact design make it suitable for a wide range of industrial, mobile equipment, agricultural, and construction hydraulic systems.
