Groco Extra Long Stainless Steel Thru-Hull Fitting

The Groco Extra Long Stainless Steel Thru-Hull Fitting is a marine through-hull fitting built for boats with thick hull sections. The extended body gives you enough thread to secure the fitting through heavy fiberglass, cored, or wood hulls. Use it for seacocks, raw water intakes, discharges, bilge and other plumbing runs.

Key Features:

• Extra long NPSM / NPT combination thread for thick hull sections
• Made from #316 stainless steel for corrosion resistance in marine environments
• Combination thread works with NPS and NPT mating hardware, such as seacocks and valves
• Part of the Groco THXL-WS series, which also has bronze models

Groco designs and manufactures marine plumbing hardware, and this fitting is a dependable choice for new installations and replacements. Pick the variant that matches your hole and thread requirements.
