Groco Bronze Flush Thru-Hull Fitting

The Groco Bronze Flush Thru-Hull Fitting is a marine-grade bronze thru-hull for boat plumbing. It is used for drains, raw-water intakes, and discharge lines that pass through the hull. The machined flat face sits flush with the hull. This makes it suited to flush-mount and dripless applications. Each fitting comes with a locknut.

Key Features:

• Bronze construction for corrosion resistance in marine environments
• Flush-style flat face for a clean, low-profile exterior installation
• Includes a locknut with a bonding screw, so the fitting can be tied into the vessel's bonding system
• Straight pipe (NPS) threads. Used with tapered (NPT) fittings, it is for low-pressure applications only, with generous use of pipe sealant or thread tape
• Available in several pipe sizes to match different plumbing runs

Important: Not to be used in potable water systems.

Groco is a well-known name in marine plumbing, and its bronze fittings are used on sailboats and powerboats. This line gives boat owners a dependable through-hull connection for common onboard systems.
