Defective valve
Item is defective. As soon as I screwed the valve onto the canister with the valve closed, fluid leaked everywhere including hitting me in the face and burning. Amazon says I can't return it or get a refund. Nonsense.

Well made, complete kit for flushing linesets
I recently replaced a compressor and coil and changed refrigerants from R22 to R410. Rather than replace the lineset and do possible drywall damage, I elected to flush the existing lineset. I pulled both Schrader valve cores, put the rubber tip against one of the schraeder bodies and slowly opened the valve. The solvent in the can did an excellent job of flushing out the old oil and crud. I then followed it up with a dry nitrogen blast to remove any residue.This kit with the 1lb can is much easier than dealing with bulk solvent, measuring, possibly spilling or contaminating the flush. It's really the right way to go and makes invoicing the customer easier.

Blew out a bunch of crud. Glad I tried it, will use it again.
I’ve got an old R-502 Chest freezer designed for -40. It’s been sitting in the storage garage for 20 years. For fun, I decided to fix the leak, clean the chiller portion, and put it to use freezing food items.I removed the cleaner/dryer, flushed all the coils and lines, and now I’m in the middle of the rebuild.I used ‘HVAC Guys Line and System Flush Kit - 1lb Can for Systems 2-4 Tons’ for the flush. The crud and old oil blew out into a bucket of rags. I was surprised by the buildup of old oil crud if the 20 old system. I did a series of line flush then nitrogen flush, the line flush again. I even let it sit in the system. I think I might be able to make this old system run again!I know I can buy other flush kits, but instead, I’m buying refills for this kit. Super easy, and I got great results
