Whitecap 316 Stainless Steel 90 Degree 1-1/2 Inch Thru-Hull Fitting with Barb

This Whitecap thru-hull fitting is a packaged 90 degree elbow fitting built from 316 stainless steel with a plastic barb component, sized for 1-1/2 inch hose. It is designed to pass hose runs through the hull at a right angle, letting the hose enter and exit the boat's skin fitting without a sharp bend that could kink the line or restrict flow. The 90 degree design is useful in tight installations such as bilge pump discharge, livewell drains, washdown lines, and other through-hull plumbing where space behind the hull does not allow a straight-through fitting.

The 316 stainless steel body resists corrosion in saltwater and freshwater environments, making it suitable for long-term marine use, while the integrated plastic barb end provides a secure, ribbed connection point for clamping 1-1/2 inch hose. The fitting is sold packaged as a complete unit, ready to install through a properly sized hull opening with a mounting flange sealed against the hull and hose clamped to the barb on the interior side.

What hose size does this fitting accept? This Whitecap thru-hull fitting is sized for 1-1/2 inch hose, with a barbed end designed to hold the hose securely when clamped.

What material is the Whitecap S-3812C made from? It is constructed of 316 stainless steel with a plastic barb component, combining corrosion resistance in the body with a ribbed barb fitting for a secure hose connection.

Is the 316 stainless steel body corrosion resistant? Yes, 316 stainless steel is a marine-grade alloy chosen for its resistance to corrosion in both saltwater and freshwater environments, which is why Whitecap uses it for the S-3812C thru-hull body.

Why choose a 90 degree thru-hull fitting instead of a straight one? A 90 degree design like the Whitecap S-3812C allows the hose to make a right-angle turn at the hull, which is useful in installations with limited space behind the hull where a straight-through fitting would not fit or would kink the hose.
