Spin-On Filter for Oil and Hydraulic Systems

The Baldwin Filters PT86-HD is a spin-on element designed for full-flow lubrication or hydraulic circuits. It fits equipment that accepts a 4 1/2 inch outside diameter and an 8 15/16 inch length. The 23 micron rating targets standard contaminant removal in automotive and industrial fluid systems. Maintenance teams use it where a direct-thread canister is specified.

Capacity and Service Limits

The element provides 23 micron nominal filtration for oil or hydraulic fluid passing through a 1 25/32 inch inside diameter. It handles flow rates typical of full-flow lube circuits but will not suit bypass-only housings or ultra-fine filtration needs. Service intervals depend on the host machine's duty cycle and fluid condition monitoring. Buyers needing a finer micron rating or a different thread interface must select another part.

Included Gaskets and End Seals

Two gaskets and two attached end seals ship with the filter, eliminating the need to source sealing hardware separately. The attached end seals simplify installation by staying in place during thread engagement. Spare gaskets allow a clean change-out if the first seal is damaged during removal. No mounting hardware, tools or fluid are included.

Questions about this item

Will the PT86-HD fit the same housing as my old filter that uses a 1 25/32 in inside diameter?

Yes, the inside diameter of this filter is 1 25/32 in, so it matches housings with that same dimension.

How can I confirm the filter is sealing correctly after I spin it on?

The unit ships with two gaskets and two end seals already attached; after installation, run the system and check for leaks at the gasket and seal surfaces.

Does the box include the gaskets and end seals, or do I need to order them separately?

Two gaskets and two end seals are included in the package, so no extra sealing parts are required.
