Groco TH-3000-W Bronze Standard Length Thru-Hull with Nut, NPS Thread

The Groco TH-3000-W is a premium bronze thru-hull fitting designed for reliable below-waterline marine applications. Constructed from durable bronze for superior corrosion resistance in saltwater environments, this standard length thru-hull features NPS (National Pipe Straight) threading for secure installation.

Key Features:

• Bronze construction provides excellent corrosion resistance in marine environments
• Standard length design accommodates typical hull and butt block thickness
• NPS threaded configuration ensures compatibility with standard marine seacocks and valves
• Includes mounting nut for secure installation
• Flange design allows for proper sealing against hull interior

Installation Notes:

The threaded portion should be cut to the proper length based on your specific hull thickness and butt block dimensions. When installing with a seacock, be sure to account for the thread depth required. Marine-grade sealant is recommended between the hull and the thru-hull flange to ensure a watertight seal.

Important: This fitting is NOT approved for use in potable water systems. Suitable for raw water applications including engine cooling, livewell, washdown, and bilge discharge systems.
