Small Nipple"

The 3/16″ Copper Access Valve is a specialized service port designed for precision refrigeration systems. Often used where space is limited or on smaller-diameter tubing, this valve provides a permanent, leak-proof point for charging refrigerant, measuring pressures, or performing vacuum evacuations. Constructed with a high-purity copper stem and a robust brass head, it is engineered to be brazed directly into capillary lines or small domestic cooling circuits.
