Designed for reliable marine plumbing and drainage applications, the LGRIG® Stainless Steel/Nylon Straight Thru-Hull Fitting with Barb provides a practical connection between a boat hull and compatible hose. Featuring a durable nylon body, stainless steel trim and an integrated hose barb, this straight thru-hull fitting combines lightweight construction with a clean, attractive exterior finish.
The stainless steel trim, also commonly described as a stainless steel cap or stainless steel face, gives the fitting a polished appearance around the hull opening, while the barbed tail provides a secure connection for the appropriate hose.
Its straight configuration allows a direct hose route without the additional space required by a 90-degree fitting. Available in sizes from 5/8" to 2", this marine skin fitting can be used for boat drains, sink drains, cockpit drainage, bilge pump discharge, livewell drainage and other marine plumbing applications.
The combination of a nylon body and stainless steel trim offers a lightweight and corrosion-resistant alternative to conventional metal fittings.
Suitable for boat building, maintenance and replacement projects, this stainless steel/nylon thru-hull fitting with barb is a practical choice for marine drainage and fluid discharge systems where a straight hose connection is required.
