Product Identity
The Baldwin Filters B481 is a spin-on oil filter designed for HVAC systems requiring a 3/4 inch thread connection. It serves technicians and maintenance teams needing a direct-replacement full-flow lube element with a 9.8 micron rating.
Compatibility Check
Verify that the host equipment uses a 3/4-16 thread size and can accommodate the 6-5/8 inch overall length. Confirm the bypass valve setting of 50 psid matches the system specification before installation.
Build and Daily Use
The transparent housing allows visual inspection of element condition while the integral G381-A gasket simplifies sealing during spin-on mounting. A 50 psid bypass valve protects flow if the media becomes restricted during service intervals.

Questions about this item
Does the B481 spin-on filter come with a gasket or must I buy one separately?
It includes a G381-A integral gasket so no separate gasket is needed.
How do I decide between the B481 and other Baldwin spin-on filters?
Match the 3/4"-16 thread, 9.8 micron rating, 50 psid bypass and 6-5/8" height to your engine specs.
What does the 9.8 micron rating mean for my engine once installed?
It traps particles down to 9.8 microns while the 50 psid bypass valve maintains flow if the element clogs.
