DeWalt Regulator
The regulator adjustment knob on my DeWalt air compressor broke. I ordered this replacement part and swapped it out. It works like a new one again.

subpar parts quality.
got the part fast and the customer service was great however the manifold came with the gauges upside down and the posts for the screws were not threaded. Ended up using a tap to thread the posts and left the gauges upside down not knowing if I rotated them they would leak. Quality of the part is subpar.

Dewalt compressor regulator.
I used standard shipping, which took longer than expected. Like 10 business days or something. I was renting a tool, to keep working. I guess I should have spent that money on next day shipping.
Otherwise, part fit exactly as original, compressor works again like new!

It pumps up to 150, (it should go to 225)and doesn't shut off. I'm just thinking it's a regular problem.

Hi Doug,
Thank you for your question. If the compressor does not build pressure and does not shut off, you likely have a defective reed/check valve and it will need to be replaced.

If you need help placing an order for it, customer service is open 7 days a week and anyone will be happy to assist you. Please feel free to give us a call. We look forward to hearing from you!

Hello Jose, thank you for your inquiry. We were unable to find a type 9 for your model D55146. However, we do have a return policy where our site offers 365-day returns on all parts that have not been installed. And, the Manifold part N028208 is the same for types 1-4 so there is a good chance it will be a fit. If you need help placing an order, customer service is open 7 days a week. Please feel free to give us a call. We look forward to hearing from you.

Simple project -take off the the screws holding the manifold and the metal shroud-unhook the hoses connected-reattach the brass fittings with making sure you use thread tape-and screw it all back together. Fire it up and it worked like a charm. Easy as pie.

Easy , you'll need a 1/2 inch hose clamp, attach the air line to the replacement manifold and replace hex screws and done! Every thing was in the package but that one 1/2inch hose clamp. If that was in the box it would be perfect.
