Groco HSTH1250W Bronze High Speed Thru-Hull Fitting 1-1/4 Inch

The Groco HSTH1250W is a bronze high-speed thru-hull fitting designed for marine plumbing applications where low pressure and low profile water flow are required. This standard-length fitting features a 1-1/4 inch diameter opening and is constructed from corrosion-resistant bronze for durability in harsh saltwater environments.

Key Features:

• Bronze construction for superior corrosion resistance
• High-speed design minimizes turbulence and flow restriction
• Low-profile installation for streamlined hull appearance
• Standard length configuration for typical hull thickness applications
• 1-1/4 inch diameter connection
• Includes mounting nut for secure installation

This thru-hull fitting is ideal for raw water intake systems, livewell circulation, washdown pumps, and other non-potable water applications on boats and marine vessels. The high-speed design allows for efficient water flow while maintaining structural integrity through the hull. Not approved for potable water systems.
