Groco Bronze Extra-Length Thru-Hull Fitting with Locknut

The Groco Bronze Extra-Length Thru-Hull Fitting with Locknut is a marine through-hull fitting for boats with thick hulls. It suits installations where hull thickness calls for a longer fitting than standard. It is also called an extra-long thru-hull or XL through-hull fitting, and it works for new builds and retrofits.

Key Features:

• Extra-long body: Made for thick or cored hull sections where a standard-length fitting would not reach.
• C83600 bronze construction: Resists corrosion, so it holds up in harsh marine environments.
• NPSM/NPT combination thread: Fits a wide range of marine plumbing setups.
• Locknut included: The fitting comes with its locknut for installation.
• UL listed: Meets UL 647B for marine thru-hull fittings.

Important: Not for use in potable water systems.

Groco is a long-established name in marine plumbing hardware. This fitting is a dependable choice for raw water intake, discharge and other through-hull plumbing needs on sailboats and powerboats.
