Engineered for dependable drainage and ventilation connections.
Mirror-finish stainless complements any transom or topsides hardware.
Ideal for upgrades and replacements where corrosion-resistance and clean aesthetics matter.

Rugged Stainless Construction

Cast from certified enhanced #316 stainless steel for exceptional strength and lifetime corrosion-resistance.
All visible areas are polished to a mirror finish, then passivated for additional protection.
Thick steel sidewalls withstand continual stress and hose flexing.

Solid Silicone Gasket

Dimensionally stable—will not deteriorate or shrink over time.
Excellent resistance to UV and weather-aging.
Watertight, fool-proof, one-piece seal.
Eliminates the need to form and apply sealant or caulk.
No more chemicals, solvent-soaked rags, or cleanup.
More than pays for itself in saved labor and cleanup time.
Guaranteed good looks thanks to perfect fit and concealment built into 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 include wrench flats or an end notch for a secure grip—one installer can tighten all connections from inside the hull.
Barbed tail ends provide ample room to hold multiple clamps.
