If you’d like to add the Argon Backpurge kit to your frame fixture we offer this kit to make it simple. You can piece it together yourself and probably save a few bucks, but I feel like it’s legitimately a chore to track all of this stuff down and get it integrated nicely. We put it all together for you. Easy. We choose to use 6mm hose and the threaded fittings on our fixture are M12 x 1.5mm. Just connect the 6mm hose to your argon source. Comes with gas switch, machined and laser marked switch plate, push-connect adapters, manifold, and 25’ / 7.5m of hose. The Bottom Bracket Mount on The Stay Slayer takes the same fitting. If you want to buy these fittings directly from McMaster Carr this is the Part Number: 5225K396
