Automotive Spin-On Oil Filter

This Baldwin Filters B40140 is a spin-on oil filter designed for automotive HVAC and lubrication systems. It fits engines or equipment that require an M20 x 1.5 thread connection. The unit is supplied new and ready for installation during routine maintenance.

Filtration Limits at 10 Micron Rating

The filter media captures particles down to 10 micron, providing a defined barrier against fine contaminants. A 30 psid bypass valve opens if the element becomes restricted, ensuring oil flow continues under cold starts or heavy loading. An anti-drainback valve retains oil in the filter after shutdown for faster pressure recovery on restart.

Direct Replacement for Worn Spin-On Units

This filter replaces an old spin-on cartridge that has reached its service interval or shows signs of bypass activation. The jump is worth it when the previous element can no longer hold 10 micron efficiency or when the anti-drainback function has degraded. It is not for systems requiring a different thread pitch, a cartridge-style housing, or a finer micron rating than 10.

Questions about this item

Is the B40140 the only spin-on filter Baldwin offers with an M20 x 1.5 thread?

The B40140 is a spin-on oil filter with an M20 x 1.5 thread, a 10 micron rating, and a 30 psid bypass valve. Other Baldwin models may share the thread size but differ in micron rating, length, or valve specification.

How does the 10 micron rating affect filtration in my engine?

A 10 micron rating means the filter media captures particles 10 microns and larger, protecting bearings and wear surfaces from fine abrasive debris that passes through coarser screens.

Will the M20 x 1.5 thread seal correctly on my engine block?

The M20 x 1.5 thread matches the factory specification for many applications; the included anti-drainback valve and 30 psid bypass valve ensure proper sealing and oil flow during cold starts and pressure spikes.
