## Description

Fitment - 1.5" Sch 5/10/40 Pipe & 1.75" Tube

Review: custom Sportster pipes. - these are really nice purge plugs ... i ended up putting the 1/8"NPT to tiny hose barb in my spare parts box. and went to the hardware store to figure out a way to connect my shielding gas regulator to the inlet purge plug. I got it down to as simple as a flare nut and an 1/8 NPT close. I had to tap the end of the flare nut to fit the close.. but it is now a nice compact tool for welding my exhaust, and I can easily move my shielding gas to the purge when needed.
Review: Good product - These work as they should and are good for the price. I used them for back purging pipe(sch 10/30/40).

## Features

- 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 Diffuser Fitting, and (1) 1/8" NPT Vent Fitting, Pre-assembled and ready for use.
- Back Purge Titanium, Stainless Steel, Inconel with little to no set up time
- Temperature Rating 600 Degrees F
- Fitment - 1.5" Sch 5/10/40 Pipe & 1.75" Tube
