Stainless Steel Thru-Hull Standard Straight Barbed - 1-1/2" Inner Diameter

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 Thru-Hull 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
