Complete Kit Covering All Most Common Sizes From 1.25" - 4" (Set of 12 Plugs).
Easy Installation and Removal. Fitting sleeves can simply be pushed out and transferred to another plug. Since the sleeves are 1/8" NPT, you have the ability to use different fittings, and increase or decrease the feed/vent sizes. The internal diffuser fitting allows for a smooth, even, non turbulent argon flow into the tube/pipe. This allows for argon to fill the tube/pipe quicker, saving you on gas and time. Internal diffusers are a must when back purging, especially on larger diameter tube/pipe.
Fittings Included, (1) 1/8" NPT Barb Fitting, (2) 1/8" NPT Sleeves, (1) 1/8" NPT Internal Diffuser Fitting, and (1) 1/8" NPT Vent Fitting, Pre-assembled and ready for use.
