Supco A1 Adjustable Line Tap Valve

The Supco A1 Adjustable Line Tap Valve is a professional-grade, clamp-on refrigerant access fitting from Supco's Signature Series. Designed for permanent installation, it allows HVAC/R technicians to gain access to system refrigerant on copper suction or liquid lines without evacuating the system first.

Compatible with 1/4", 5/16", and 3/8" O.D. tubing, the A1's adjustable design and included adapter sleeves make it a versatile single-valve solution for the most common line sizes found in residential and light commercial refrigeration and air conditioning systems. The patented depressor valve action automatically closes the valve port when the charging hose is removed, preventing refrigerant loss.
