Long Skin Fittings

TruDesign Long Skin Fittings comply to ISO 9093-2. and ABYC H-27 (when used with ABYC Collar)
Designed and made in New Zealand, the Skin Fitting body and nut are moulded from a glass-reinforced nylon composite. High strength, high-modulus glass fibres provide dramatic strength, stiffness, toughness and dimensional stability. These properties allow a significant weight reduction over metallic fittings.
TruDesign Skin Fittings eliminate the corrosion and electrical bonding problems associated with metallic fittings.

When used in below waterline applications, a Ball Valve should be directly connected and installed as per manufacturers instructions for safety and compliance to relevant marine standards.
