Whitecap Industries 90 Degree Thru-Hull Fitting with Barb, 5/8 Inch Hose, 316 Stainless Steel and Nylon, S-3807C

The Whitecap Industries S-3807C is a 90 degree thru-hull fitting with a barbed hose connection, built from 316 stainless steel and nylon for corrosion resistance in marine environments. It is designed to pass a 5/8 inch hose through a boat hull at a right angle, routing plumbing or drainage lines while keeping the through-hull connection watertight and secure. The 90 degree bend allows the hose to run parallel to the hull surface immediately after passing through, which is useful in tight bilge or transom installations where a straight thru-hull would not leave enough clearance.

The fitting combines a stainless steel flange and body with a nylon barb section sized for a 5/8 inch hose, and it uses NPT threading. The flange has a 1-7/8 inch outer diameter, the thread length measures 1-5/8 inches, and the barb itself extends 7/8 inch to give the hose clamp solid purchase. Overall length of the fitting is 3-1/8 inches. It requires a cut out of 1-15/16 inches in the hull and is rated for a maximum hull thickness of 1-1/4 inches. The finish is a silver stainless steel exterior that resists corrosion from saltwater and marine exposure.

This thru-hull fitting suits boat owners installing or replacing bilge pump discharge lines, livewell drains, washdown lines, or other 5/8 inch hose plumbing that needs to exit the hull at a 90 degree angle. It ships as a single packaged unit weighing 0.2 pounds.
