Designed for reliable marine plumbing and hull drainage applications, this Nylon Straight Skin Fitting with Hose Barb provides a convenient connection between a boat hull and a flexible hose. The straight-through design allows the fitting to pass directly through the hull, while the integrated hose barb provides a secure connection for compatible hose.
Manufactured from durable nylon, this marine skin fitting offers a lightweight construction and good resistance to corrosion and electrolysis compared with conventional metal fittings. The molded flange provides a clean external finish against the hull surface, while the threaded body and retaining nut allow the fitting to be securely mounted through the hull.
The straight configuration is particularly suitable for installations where a direct hose connection is required without the additional space of a 90-degree elbow. Available in multiple sizes from 5/8" to 2", this nylon thru-hull fitting can be used for boat drains, cockpit drainage, sink drains, bilge pump discharge, livewell drainage and other marine plumbing applications.
Its simple construction, lightweight nylon body and integrated hose barb make it suitable for boat building, maintenance and replacement projects. This marine skin fitting is a practical choice for above-waterline drainage and fluid discharge systems where a dependable straight hose connection is required.
