Baldwin PT9180 Hydraulic Filter Element

This Baldwin PT9180 is a hydraulic filter element designed for fluid power systems. It features a silicon carbide construction with an attached spring and integrated by-pass valve. The element includes an O-ring for sealing and measures 2-3/4 inches in outside diameter by 3-5/8 inches in height. It fits equipment requiring this specific element configuration.

Suits maintenance on compatible hydraulic circuits

Technicians servicing hydraulic systems that accept a 2-3/4 by 3-5/8 inch element with an attached spring and by-pass valve will find this part matches their requirements. It is not intended for applications needing a spin-on canister assembly or a different element diameter. Buyers without a cross-reference confirming the PT9180 fitment should verify specifications before ordering.

Critical fitment: 2-3/4 x 3-5/8 inch element

The decisive specification is the element geometry: an outside diameter of 2-3/4 inches and a height of 3-5/8 inches combined with the attached spring and by-pass valve. This physical profile determines whether the PT9180 seats and seals correctly inside the filter housing. Confirm these dimensions and the spring feature against the original equipment part number to ensure compatibility.

Questions about this item

What hydraulic system thread size does the PT9180 element require to seal properly?

The element has a 1-3/32 inch inside diameter and includes an attached O-ring, so the housing must accept that bore size for a correct seal.

Can I keep my existing bypass valve housing when installing this PT9180 filter?

This element already includes a built-in bypass valve and attached spring, so the original housing valve can remain but the filter provides its own pressure relief.

How do I confirm the PT9180 is flowing correctly after installation?

Check system pressure gauges for normal operating range and inspect the housing for leaks around the O-ring; stable pressure indicates the element and bypass are functioning.
