Is the Dewalt 1000002673 check valve compatible with all Dewalt air compressors?
No. The 1000002673 check valve fits select Dewalt, Porter-Cable, Craftsman, and Bostitch compressor models only. Common compatible models include D55167, D55168, D55146, and several related compressor systems. Always verify your exact model number before ordering.

Why is my Dewalt compressor leaking air from the check valve area?
This usually happens when the internal valve seal becomes worn or debris prevents the valve from closing fully. A faulty check valve can allow tank pressure to leak back toward the pump, causing continuous hissing and pressure loss after shutdown.
-
Can I replace the Dewalt 1000002673 check valve myself?
Many compressor owners replace this valve using standard hand tools. Before installation, disconnect electrical power, fully drain tank pressure, and apply proper thread sealant to prevent leaks. Ensure the replacement valve matches the original fitting size and orientation.

What does the Dewalt air compressor check valve do?
The check valve allows compressed air to flow from the pump into the air tank while preventing reverse airflow after the compressor shuts off. This helps maintain stored tank pressure, reduces startup strain on the motor, and supports efficient compressor operation.
