GROCO 1.5-Inch 90-Degree Hose Thru-Hull Fitting

The GROCO 1.5-Inch 90-Degree Hose Thru-Hull Fitting gives a durable connection point for compatible marine plumbing where water must pass through the hull or transition between threaded pipe and hose. Its GROCO marine-metal construction is designed for the demanding environment associated with raw-water, drain, or other approved onboard systems.

The specific thread and hose geometry named in this model determines how it integrates with seacocks, valves, hose, or other plumbing hardware. Some bronze fittings in this family are intended for raw-water and utility service rather than potable-water systems, so the application must be verified before installation.

Confirm thread standard, connection size, hull thickness where applicable, hose compatibility, fluid service, bonding practices, and required installation hardware before mounting. Use appropriate marine sealant and clamps, support connected plumbing to reduce strain, and inspect the completed installation carefully for leaks. See our other bilge and water pumps.

• The fitting joins compatible hull, pipe, or hose components.
• Model-specific threads and hose interfaces support proper system fit.
• Marine-metal construction is selected for the intended application.
• Correct bedding, support, and connection hardware help prevent leaks and strain.
