Baldwin BT8421-MPG Hydraulic Filter

This Baldwin Filters BT8421-MPG is a spin-on hydraulic filter rated at 5 micron for fine contamination control. It uses Maximum Performance Glass media to protect hydraulic systems in heavy equipment and industrial machinery. The unit includes a G369-B gasket for a secure seal upon installation.

Suits 1-1/2 Inch -16 Thread Assemblies

This filter fits assemblies requiring a 1 1/2 in. -16 thread size, such as the Donaldson HBK05 housing. It is not for systems using a different thread pitch or diameter. Buyers needing a coarser micron rating or a cartridge-style element should look at other options.

5 Micron Rating With Glass Media

The 5 micron rating combined with Maximum Performance Glass media determines the filtration efficiency for this application. This specification confirms the filter captures fine particles to maintain fluid cleanliness. Verify the micron requirement matches your system specifications before purchase.

Questions about this item

How does the 5 micron rating affect flow restriction during continuous hydraulic operation?

The 5 micron glass media captures fine particles while maintaining steady flow through the spin-on housing.

What thread size must the existing filter head have to accept this BT8421-MPG?

The filter uses a 1 1/2 In. -16 thread, so the mounting head must match that specification.

Will the supplied G369-B gasket seal properly on a Donaldson HBK05 assembly I already use?

Yes, the G369-B gasket is furnished for direct compatibility with the Donaldson HBK05 assembly.
