Daystate compressor

I had a leak under the gauge, I try to take it off to fix it and it broke. Where I can find a new gauge and how can I put it back.. but it looks like it was already cracked..

You need a center back mount 1/4NPT 0-6000psi liquid filled gauge. Directmaterials.com sells Durachoice brand gauges at very good prices. The link above is to the right vendor but you need a 1/4”NPT threaded gauge, not a 3/8”NPT. There are broken screw removal bits that are reverse threaded that you can buy cheap. Put one in a drill and as you run the drill in reverse it will drill into the hole of the broken brass part that is in your gauge connection until it has enough bite to unscrew it from the filter tower. A set of 4 is about $5 or less at Home Depot, Lowe’s, or Harbor Freight. It’s easy. Since your gauge shows corrosion you might consider squirting some anti seize lubricant to loosen the threaded piece stuck in the water separator hole. The gauge you need is part # PBG254B-K06. It is $9.40 on their website. Put 3 winds of Teflon tape on the threads to seal it and tighten it wrench tight.

This is not a complicated repair and it would be cost prohibitive and unnecessary to ship the compressor to fix this issue.
 
This one is brand new I got it like 2 years ago and used it like 4 times. I think I has warranty but it’s to expensive the shipping to send it back to AZ lol, I’m in MA .. I don’t think it’s to hard to replace the gauge..

If it's within the 2 year warranty then call AOA quick for the part. Why pay if it's under warranty up to 2 years from date of purchase.
 
I may have read something about Nuvair not wanting to help Daystate compressor owners and it's somewhere on THIS FORUM.

That was not my experience. I have a Daystate T2 and Nuvair has given me tech help on the phone and been happy to sell me parts.

I would not expect them to do warranty work though because of it being a private labeled product not sold through the Coltri dealer network.
