Groco Bronze High Speed Thru-Hull Fitting

The Groco Bronze High Speed Thru-Hull Fitting is a marine through-hull (thru-hull) fitting. It gives water a low-profile path into or out of a boat's plumbing system, such as raw-water intakes and discharge lines. It is designed to move more water than a standard thru-hull and to create less drag.

Key Features:

• Higher flow, less drag: The design increases flow compared with standard thru-hulls and reduces drag.
• Cast bronze construction: Made from C83600 bronze, a material widely used in marine hardware.
• Combination thread: The NPSM / NPT combination thread works with common marine seacocks and plumbing components.
• Nut included: Each fitting comes with a mounting nut.
• Low-profile fit: The low-profile design suits hull installations where a flush, streamlined fitting is needed.

Groco is a long-established name in marine plumbing, known for seacocks, strainers and thru-hull fittings. This fitting suits boat owners and installers who want a durable bronze thru-hull for below-waterline plumbing. It is not intended for use in potable water systems.
