3 in 1 Line Piercing Valves 



542-C  Fits  3/8”, 1/2” and 5/8” O.D. tubing.

Fast, easy, secure installation. Provides access to line at any point for charging, testing or evacuation. Two valves cover 3/16” to 5/8” O.D. tubing. Both have depressor valve and needle valve shut-off. Valve clamps on tubing line with two captive slotted-head screws: positive built-in mechanical stop for each tube size eliminates tightening guesswork.
To pierce tube, thread down the 
combination l/4” flare port, stem and needle using knob furnished or a suitable wrench, back off stem and connect depressor-type hose for testing or charging. After service is completed valve is closed and left on line for future service. Dust cap provided.

Three-point sealing [(1) needle-type valve, (2) gasket and (3) check valve] prevents 
leakage. Neoprene seal withstands temperatures near 300°F.

541-C  Fits 3/16”, 1/4” and 5/16” O.D. tubing.

542-C  Fits  3/8”, 1/2” and 5/8” O.D. tubing.
