TruDesign Domed Skin Fittings (Thru Hulls)

  • 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.

TruDesign Skin Fittings are certified by the International Marine Certification Institute (IMCI) & Bureau Veritas to meet ISO 9093-2 Small craft — Seacocks and through-hull fittings — Part 2: Non-metallic

  • When used in below waterline applications, a Ball Valve should be directly connected for safety and compliance to relevant marine standards.
  • An Application Tool is available to allow the skin fitting to be installed by one person.
  • Please download the Data Sheet for dimensions, features and installation instructions.
  • Suitable Adhesive/Sealant for bonding the skin fittings can be found here.

Supplied with the main body, sealing washer and flanged nut.
