Polish your image with the new Standard Thread Thru-Hull. Why specify plastic parts when these fittings will last the life of the boat? For hulls to 2" thick.

Rugged Stainless Construction

• Cast from certified #316 Stainless Steel alloy for strength and lifetime corrosion resistance.
• We polish all visible areas to a mirror finish, then send each part through passivation for additional protection.
• Thick steel sidewalls withstand continual stress and hose flexing.

Cast bronze, with nut.
