TruDesign Tails / Hose Barbs are moulded from a glass reinforced nylon composite. High strength, high modulus, glass reinforced nylon provides dramatic strength, stiffness, toughness, and dimensional stability. TruDesign Tails / Hose Barbs eliminate the corrosion and electrical bonding problems associated with metallic fittings. The Tails are designed for twin hose clamps, and to not crush under high load conditions.
