Kegconnection, LLC1/4 Inch Flare White Washer - 25 pack

I'm using these to seal lines that are troublesome to seal, high pressure refrigerant lines. I hope they work. Much cheaper than the fancy blue ones from the hvac supplier. Sometimes the flare is scratched and today's r410a is a high pressure refrigerant that will leak past a scratch.wish me luck!

I ordered these because it was a good deal, but I really didn't need so many. They arrived and solved my problem. I kept a few for myself and then gave the rest to the local homebrew store.

I needed more of these for new mfl connectors i bought but they had them built in. These were still quality washers and they came quick and were good for the price

Ordered 2 packs of 25 to change out all connections on home made draft system. All parts worked well, not more CO2 leaks. Price was significantly lower then elsewhere, good buy.

It helped stop small gas leaks.
