Baldwin BT9471 Hydraulic Spin-On Filter
The Baldwin BT9471 is a hydraulic spin-on filter designed for fluid power systems requiring reliable contamination control. It serves technicians and equipment operators who need a direct replacement cartridge with a 9.8 micron rating and integral sealing.
Spin-on interface with M24-1.50 thread
This filter uses a spin-on mounting design with an M24-1.50 thread size for installation onto compatible filter heads. The practical limit is the thread specification itself; the housing must match this exact pitch and diameter to seal correctly. The unit includes a 40 psid bypass valve that opens when the element reaches its dirt-holding capacity, preventing oil starvation. An integral gasket is moulded into the canister to simplify the seal.
9.8 micron rating decides suitability
The single specification that determines fit is the 9.8 micron nominal rating, which defines the particle size the media captures under test conditions. If the hydraulic system demands finer or coarser filtration, this cartridge will not meet the cleanliness target. The canister measures 3 45/64 in in length and 4 3/16 in in height with an outside diameter of 3 23/32 in for clearance checks. Buyers who need a different micron rating or thread form cannot use this part.

Questions about this item
Which Baldwin BT9471 specification should I match to my equipment — the thread size or the micron rating?
Match both: the filter uses an M24 × 1.50 thread and a 9.8 micron rating, so your hydraulic system must accept that thread and require that filtration level.
What does the 9.8 micron rating mean once the filter is installed in my hydraulic circuit?
It means the element will trap particles down to 9.8 microns, keeping the hydraulic fluid clean enough for components that specify that cleanliness class.
How does the M24 × 1.50 thread and 40 psid bypass valve limit what this filter can handle in practice?
The M24 × 1.50 thread fixes the mounting interface, and the 40 psid bypass valve opens if the element clogs, capping the maximum pressure differential across the filter at 40 psi.
