Stainless Steel Std. Thru Hull 1 1/2" Hose

Product Description

Upgrade your vessel’s plumbing and aesthetics with our premium 316 stainless steel thru-hull fitting. Engineered for marine environments, this fitting resists rust, corrosion, and electrolysis—making it ideal for saltwater applications and offshore fishing boats.

With a high-polished mirror flange, this thru-hull adds a sleek, sophisticated look to any hull. Its standard thread length makes it compatible with most installations, from custom refits to factory OEM replacements.

The 1-1/2″ hose barb supports marine sanitation, bilge, and drainage systems, while the extended barb design allows for double hose clamping—a must for high-vibration environments where failure is not an option.
