1/2″ NPTF Restriction Orifice Union

First, let’s point out that the 1/2″ NPTF Restriction Orifice Union is important in protecting your gas meter from overspinning. When pressures and flow rates rise too high or too quickly, the meter’s gears can over-spin and lock up. Our made-to-order borehole orifice plate and union should be installed 2 to 4 pipe diameters downstream of the gas meter with nothing but straight pipe in between. This is such a helpful tool in not only protecting your meter from damage, but also keeping your gas lines up and running safely for years to come.
