I need to test a new gas line to my HVAC but can't find the right gauge to put the air in the line.where can I buy that from ?

Hi MB

I don't know what pressure range your local inspector requires, but I would think that any local plumbing or HVAC supplier should have the appropriate gauge.

Otherwise, if the local home improvement stores don't have the right gauge, I'd suggest stopping by a local auto parts store... they should have something that will work.

Online ordering through www.amazon.com is another, last resort, option!

Hope that helped!
