Polish your image with these beautiful, durable stainless steel fittings. Each Thru-Hull and Scupper Valve is backed by Attwood's trusted Lifetime Warranty! Why specify plastic parts when these fittings will last the life of the boat? This product does not include a gasket.

Rugged Stainless Construction

  • Cast from certified enhanced #316 Stainless Steel allow for strength and lifetime corrosion-resistance
  • We polish all visible areas to a mirror finish, then each part through a passivation for additional protection
  • Thick steel sidewalls withstand continual stress and hose flexing

Faster, Simpler Installation

  • A channel under the flange holds a bead of sealant, making it easier to apply a trouble-free seal
  • All models have wrench flats or an end notch to hold as a gripping surface. One installer can tighten all connections from inside the hull
  • Barbed tail ends provide plenty of room to hold multiple clamps

Caution: Thru-Hull connectors are designed for installation above the water line only.
