Stainless Steel Std. Thru Hull 5/8 Hose

Product Description

Enhance your vessel's plumbing system with our solid cast 316 stainless steel thru-hull fitting—designed for long-lasting performance and sleek aesthetics in even the harshest marine environments.

With its mirror-polished flange, this fitting adds a refined, professional look to any boat hull. The standard thread length offers compatibility with most fiberglass and composite boats, making it a go-to choice for DIY installs, refits, and OEM replacements.

The 5/8″ hose barb is ideal for smaller plumbing lines, while the extended barb allows for double clamping—a must-have for high-vibration or offshore conditions where a leak-proof connection is critical.
