Baldwin Filters BK6089 Service Kit

This Baldwin Filters BK6089 service kit is a complete maintenance package for Thermo King refrigeration units. It bundles a B7375 lube spin-on, a BF9893 fuel spin-on, and an RS5387 radial seal air element with lid. The kit matches Thermo King cross-reference 19-0-449 for straightforward parts identification.

For Thermo King unit maintenance

This kit suits operators and technicians performing scheduled filter changes on compatible Thermo King equipment. It provides the three essential filter types in one package for efficient servicing. It is not for engines or refrigeration units that require different filter specifications or separate component sourcing.

Primary cross-reference 19-0-449

The deciding specification is the Thermo King cross-reference number 19-0-449, which confirms exact fitment for the target equipment. Verifying this number against the unit's service manual ensures the B7375, BF9893, and RS5387 components are the correct replacements. No other specification in the kit overrides this compatibility requirement.

Questions about this item

Will the BK6089 kit fit the Thermo King 19-0-449 unit I already own?

Yes, the kit cross-references Thermo King 19-0-449 and includes the B7375 lube spin-on, BF9893 fuel spin-on, and RS5387 radial seal air element with lid.

How can I confirm the BK6089 filters are sealing correctly after installation?

Start the Thermo King unit and check each filter housing for leaks; the RS5387 lid should seat evenly and the spin-ons should be hand-tight plus three-quarters turn.

Does the BK6089 box contain every filter needed, or must I purchase anything else?

The kit ships with the B7375 lube filter, BF9893 fuel filter, and RS5387 air element with lid — no additional filters are required for the listed service interval.
