Our Series SPC Port Connector Unions and SRPC Reducing Port Connectors, crafted from durable 316 stainless steel, are essential components designed to securely connect two tube fittings directly to one another. These port connectors replace the ferrules within the tube fitting, ensuring a leak-tight and reliable connection. To secure the fitting, simply insert the port connector into the tube fitting and turn the nut 1/4 turn from finger tight. Made from high-quality bar stock, these fittings are engineered with greater hardness than traditional tubing, providing enhanced durability. A small indentation on the tube side of the port connector ensures a secure connection when the nut is tightened, making these connectors an ideal solution for demanding fluid and gas transfer systems.
