Hydraulic Filter Base OB1318

The Baldwin Filters OB1318 is a steel hydraulic filter base designed for fluid power systems. It provides a secure mounting platform for compatible spin-on filter elements. The unit features 3/4 inch NPT inlet and outlet ports for standard hydraulic line connections. This new component is built for durability in demanding automotive and industrial maintenance environments.

For technicians servicing specific Baldwin housings

This base suits workshops that service equipment using Baldwin BT839, BT839-10, BT8420, BT8428-MPG or BT8443 filter cartridges. It matches the required 3/4 inch NPT port specification for those applications. Technicians needing different port sizes, thread types or filter head configurations should look elsewhere. The part is not intended for fuel, oil or coolant filtration systems using other manufacturers' elements.

3/4 inch NPT port compatibility

The inlet and outlet ports are machined to 3/4 inch NPT, which determines whether this base fits the existing hydraulic plumbing. Verify the system uses this exact thread size and pitch before ordering. The base length is 3 inches and the outside diameter is 3-3/4 inches for clearance checks. Compatibility with the listed Baldwin filter models is the primary selection factor.

Questions about this item

Will the OB1318 base thread onto the 3/4 inch NPT ports already on my hydraulic system?

Yes, both the inlet and outlet on this base are 3/4 inch NPT, so they match existing 3/4 inch NPT fittings directly.

How can I confirm the filter is sealing correctly once the OB1318 is installed?

Pressurise the system and check the base-to-filter joint and both NPT connections for any weeping; a dry joint under operating pressure shows the seal is holding.

Does the OB1318 package include a BT839 or BT8443 filter cartridge, or must I order it separately?

The base ships without a cartridge; you need to buy a compatible filter such as BT839, BT839-10, BT8420, BT8428-MPG or BT8443 separately.
