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

Solid Silicone Gasket

•  Gasket is dimensionally stable--will not deteriorate or shrink over time
• Excellent resistance to UV & weather-aging
• Watertight, fool-proof, one-piece seal
• Eliminates the need to form and apply sealant or caulk
• No moreChemicals, solvent-soaked rags,or cleanup
• More than pays for itself in saved labor and cleanup time
• Guaranteed good looks because the perfect fit and concealment is built in the gasket

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.
