TruDesign Composite thru hull 1-1 / 4'' thread (white) x 3.50'' H x 1-3 / 4'' Diam.

Tru-Design thru hulls 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. They eliminate the corrosion and electrical bonding problems associated with metallic fittings. They are designed for twin hose clamps, and to not crush under high load conditions.
