Baldwin B7443 Oil Filter Specifications
The Baldwin B7443 is a spin-on oil filter engineered for automotive lubrication systems requiring M22 x 1.5 mm threads. It carries a 12 micron rating to capture fine contaminants during engine operation. A built-in anti-drainback valve prevents oil from draining back into the sump after shutdown. An 8 PSID bypass valve ensures continued oil flow if the filter media becomes restricted.
Integrated Valve and Seal Benefits
The anti-drainback valve retains oil in the filter housing for faster pressure build-up on cold starts. The bypass valve opens at 8 PSID to protect the engine from oil starvation during cold starts or heavy contamination. An integrated gasket provides the sealing surface between the filter and the engine mounting pad. These features are part of the filter assembly and require no separate installation steps.
Fitment and Application Guidance
This filter suits vehicles and equipment specifying an M22 x 1.5 mm thread size and the listed physical dimensions. Verify the thread pitch and mounting clearance against the service manual before purchase. It is not intended for applications requiring a different thread standard, a different micron rating, or a cartridge-style housing. Buyers needing a different bypass pressure setting or a filter without an anti-drainback feature should select an alternative part.

Questions about this item
How often should I replace the B7443 spin-on oil filter?
Replace the B7443 filter at every engine oil change interval recommended by the vehicle manufacturer.
What pressure triggers the by-pass valve on this filter?
The by-pass valve opens at 8 PSID to maintain oil flow if the filter element becomes restricted.
Does the anti-drainback valve prevent dry starts after the engine sits overnight?
Yes, the included anti-drainback valve keeps oil in the filter so pressure builds faster on restart.
