The Trident S137 High Pressure Splitter Block expands a single 7/16"-20 high-pressure port into two 7/16"-20 female high-pressure ports, allowing multiple HP accessories to be connected to the same first-stage regulator. Ideal for divers using both an analog submersible pressure gauge (SPG) and a wireless air transmitter, this compact splitter provides a secure, leak-resistant solution without compromising performance. Precision-machined from chrome-plated marine-grade brass, it offers excellent corrosion resistance and durability for both recreational and technical diving applications.
