Description
This item is brand-new, factory sealed.
Stainless Steel Scupper Valve Barbed - 1-1/2" Hose Size
Polish your image with these beautiful, durable stainless steel fittings. Why specify plastic parts when these fittings will last the life of the boat?
Rugged Stainless Construction:
- Cast from certified Enhanced 316 Stainless Steel alloy for strength and lifetime corrosion-resistance
- All visible areas are polished to a mirror finish, then passivate each part for additional protection
- Thick steel sidewalls withstand continual stress and hose flexing
Faster, Simpler Installation:
- Each Scupper Valve is available with a new silicone gasket
- 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
- The barbed tail ends provide plenty of room to hold multiple clamps
Stainless Steel Scupper Valves, Barbed:
