The Whale 15mm Stem Adaptor x 1/2″ Hose Barb connects your whale pump systems to the braided 1/2in tubing that runs from your pumps and TwistnClean filter housing. This versatile fitting makes it easy to switch out pumps and filters as needed. Made from durable glass-filled polypropylene, this adaptor features a unique “Double Gripper” collet that securely retains the tubing, even under high pressures. The collet has an internal support ring to maintain the O-ring seal, preventing leaks. It can handle maximum pressures of 6 bar (90 psi) for hot water and 12 bar (180 psi) for cold water, with maximum temperatures of 65°C (180°F) for hot water and 20°C (68°F) for cold water.
