TruDesign Long Thread Tails are the superior composite connection for fitting hose to threaded fittings. TruDesign Tails are moulded from a glass reinforced nylon composite. High strength, high-modulus glass fibres impregnated into the nylon provides dramatic strength, stiffness, toughness, and dimensional stability. The Tails are designed for twin hose clamps, and to not crush under high load conditions.
