The Groco STH-1500-W is a 1-1/2" bronze scoop thru-hull fitting designed to deliver increased water flow compared to standard thru-hull fittings. The integral slotted strainer design creates positive pressure while underway, making it ideal for raw water intake applications on boats, yachts, and other marine vessels.

Key Features:

• Cast from durable C83600 bronze for superior corrosion resistance in saltwater environments
• NPSM/NPT combination thread provides versatile installation options
• Scoop design with integral slotted strainer induces positive pressure during operation
• Includes locking nut for secure installation
• 1-1/2" pipe size with 3.15" shank length

This fitting is engineered for raw water systems including engine cooling, washdown pumps, livewell circulation, and other non-potable water applications. The scoop configuration maximizes flow efficiency while the cast filter slots help prevent debris from entering your system. NOT TO BE USED IN POTABLE WATER SYSTEMS.
