Parker-Jackes Evans 70221 Brass Valve 1/4" N/C 1-150 PSI GP200

The Parker-Jackes Evans 70221 Brass Valve is a normally closed shutoff part that regulates fluid or gas flow within HVAC and refrigeration piping. The brass body withstands pressures ranging from 1 to 150 PSI, opening a passage only when actuated to permit movement through connected lines. Threaded 1/4-inch ports let the fitting join directly into copper or steel tubing found across HVAC system loops on smaller-scale units. The internal seal resists corrosion from moisture exposure, maintaining tight closure when idle. Its compact profile fits into confined spaces near compressors, keeping the piping circuit sealed while limiting pressure loss during operation.
