Fitment guide - 2.5" Sch 5/10 Pipe & 2.75"-3" Tube (WILL FIT 3" tube which has a smaller inner diameter 2.9xx") . For a use on a 3" inner diameter (Such as 3" Flanges, Flex Sections, or anything 3"-3.25") use our 3"-3.25" Silicone Plugs, which also WILL FIT 3" tube (Available for purchase separately on Amazon).

• 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.
