Groco STH-150-W 1-1/2" Bronze Scoop Thru-Hull Fitting with Nut

The Groco STH-150-W is a 1-1/2" bronze scoop-style thru-hull fitting designed for marine applications where water flow needs to be directed into the boat's plumbing system. The scoop design projects into the water flow, creating positive pressure that helps push water through intake lines, making it ideal for engine cooling systems, washdown pumps, and livewell applications.

Key Features:

• 1-1/2" NPT threaded connection for secure installation
• Bronze construction for superior corrosion resistance in saltwater environments
• Scoop profile enhances water intake efficiency under way
• Includes locking nut for secure hull mounting
• Suitable for below-waterline installations

Important: This fitting is not approved for potable water systems. Use only for non-drinking water applications such as engine cooling, deck wash, or livewell systems.

Groco marine hardware is manufactured to exacting standards and widely trusted by boat builders and marine professionals worldwide for reliable performance in demanding saltwater conditions.
