Baldwin B474 Spin-On Filter
The Baldwin B474 is a full-flow spin-on oil filter designed for automotive and heavy-duty HVAC lubrication circuits. Its M16 × 1.50 thread and compact 3-17/32 inch height suit tight engine bays where a standard cartridge housing will not fit. The transparent housing allows quick visual inspection of element condition without removal.
Replaces Cartridge-Style Housings
Switching to this spin-on unit eliminates the separate canister and centre-bolt assembly found on older cartridge designs, cutting service time and reducing the chance of cross-threading the bowl. The integral G449-B gasket seals against the block without a separate O-ring kit, so the upgrade is justified whenever the original housing leaks or the mounting studs are damaged.
Sustained Flow With Bypass Protection
Under continuous high-RPM operation the 5 micron media maintains consistent pressure drop while the 8 psid bypass valve opens only if the element loads excessively, preventing oil starvation during cold starts or extended drain intervals. The steel end-caps and centre tube resist collapse under prolonged pressure spikes, keeping filtration efficiency stable over the full service interval.

Questions about this item
What thread size does the B474 spin-on filter need for mounting?
The filter mounts on an M16 x 1.50 thread, matching the spec on the housing.
What installation step is often missed with the integral G449-B gasket?
Lubricate the gasket with clean oil and tighten only until the gasket contacts the base, then turn the recommended extra rotation.
When should the B474 filter be replaced in normal service?
Replace at every engine oil change interval; the 5 micron full-flow element and 8 psid bypass valve are single-use items.
