Baldwin Filters P7259 HVAC Control Element

The Baldwin Filters P7259 is a transparent cartridge-type oil filter element designed for Hatz engines. It measures 2-17/32 inches in length with an outside diameter of 1-21/32 inches and an inside diameter of 1/2 inch. An attached grommet and bypass valve are included for installation readiness.

Sustained load behaviour with bypass valve

Under continuous operation the integrated bypass valve opens if the element becomes restricted, maintaining oil flow to the engine. The cartridge design and attached grommet provide a consistent seal throughout the service interval. This arrangement supports steady lubrication without pressure spikes during extended running periods.

Practical limits of cartridge interface

The element relies on a housing that accepts a 2-17/32 inch length and 1-21/32 inch outside diameter, with no thread engagement required. Builders needing a spin-on canister or a different centre-thread specification cannot use this part. The fixed dimensions and grommet seal define the only compatible mounting arrangement.

Questions about this item

Does the P7259 element generate any noise, heat or power draw when the engine runs all day?

The P7259 is a passive oil filter cartridge with no moving parts, so it produces no noise, no heat and draws no power during continuous engine operation.

What must I already own for this P7259 element to work in my system?

You need a compatible Hatz engine with a filter housing that accepts a cartridge measuring 2-17/32 in height, 1-21/32 in width and 1 21/32 in outside diameter, plus the attached grommet and bypass valve included with this element.

Will the P7259 element fit alongside the original hardware on an older Hatz engine I plan to keep?

Yes, the element is designed for use with Hatz engines and its dimensions — height 2-17/32 in, width 1-21/32 in, outside diameter 1 21/32 in, inside diameter 1/2 in — match the original cartridge specifications for direct replacement.
