1.5-Inch Rear Mount High Pressure Gauge for Flowmeters (0-4000 PSI)

Keep Your Shielding Gas in Check

Running out of shielding gas in the middle of a bead is every welder's frustration. It leads to porosity, rework, and wasted time. The Western Enterprises PG15-4000R Pressure Gauge is your reliable solution for keeping an eye on your tank levels. Designed to fit directly onto your flowmeter, this gauge measures the high-pressure side of your setup, telling you exactly how much Argon, CO2, or Helium is left in the bottle before you strike an arc.

This isn't just a generic gauge; it's built for the specific needs of welding equipment. The 1.5-inch face is compact enough to stay out of your way but clear enough to read from a distance. It features a 0-4000 PSI scale, which covers the pressure of fully pressurized industrial cylinders (usually around 2000-2600 PSI) with plenty of headroom. The rear mount design with 1/8-inch NPT threads means it screws directly into the back or side port of most standard flowmeters, making installation a breeze—just use a little Teflon tape (ensure it's rated for gas) and tighten it down.

Why replace your gauge? Over time, gauges can get banged up, lenses crack, or needles get stuck. A faulty gauge is a safety hazard and a logistical headache. If you can't trust your gauge, you might swap out a tank that still has gas (wasting money) or run a tank completely dry (ruining welds). This replacement part restores your ability to manage your consumables effectively.

Compatible with all standard inert shielding gases, this gauge is a must-have spare for any shop using MIG or TIG processes. It works with pure Argon, Argon/CO2 mixes, Helium, and Nitrogen. Don't let a broken dial leave you guessing; swap it out with this durable, high-pressure gauge and keep your focus on the puddle, not the bottle.
