FEATURES

SPECIFICATIONS

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.
