Baldwin B7281 Spin-On Oil Filter
The Baldwin B7281 is a spin-on oil filter built for engine lubrication circuits that accept an M20-1.50 thread. It serves technicians and fleet operators who need a direct-fit replacement with a 14 psid bypass valve and an integrated anti-drainback valve.
Fits M20-1.50 threads and standard spin-on mounts
Installation requires a compatible M20-1.50 thread boss on the engine block or remote mount. The 14 psid bypass valve protects flow during cold starts or high restriction, while the anti-drainback valve retains oil in the filter after shutdown for faster pressure recovery.
Replaces worn or clogged spin-on cartridges
The jump is worth it when the old element reaches its service interval or shows pressure-drop symptoms. The 14 psid bypass setting and anti-drainback function restore designed flow resistance and dry-start protection without altering the mounting interface.

Questions about this item
At what pressure does the 14 psid bypass valve open under sustained use?
The built-in bypass valve opens at 14 psid to maintain oil flow if the filter element becomes restricted.
How much heat or noise does the spin-on filter generate during all-day operation?
The filter has no moving parts and produces no measurable noise or heat during normal engine operation.
What thread size must the engine block already have for the M20-1.50 filter to install correctly?
The engine block must provide an M20 x 1.50 thread for the filter to seal and install properly.
