Western manufactures Nitrogen purging regulators for use in 410a installations. Using Nitrogen displaces oxygen in the lines, minimizing the formation of oxides which can cause premature compression failure as a result of getting trapped in the TXV or metering orofice. Their regulators come in 3 sizes – 250, 500, and 650 PSI test pressure, and all use a rugged solid brass body. Additionally their handtight cylinder connection means that no wrench is required. BTU Reps is considered the strongest supply and tool representative in the southeast and proudly enjoys representing Western’s line of nitrogen purging regulators.
