  • ColorTransparent

Bronze Thru-Hull With Nut

The Groco TH-200-W is a bronze thru-hull fitting supplied with a nut for marine plumbing installations. It provides a reliable through-hull connection for water intake or discharge systems on boats. The bronze construction offers corrosion resistance suitable for saltwater environments. This fitting is designed for standard marine maintenance and repair tasks.

Replaces Worn Bronze Fittings

This unit replaces deteriorated or leaking bronze thru-hulls of the same nominal size during scheduled maintenance or emergency repair. The jump is worth it when the existing fitting shows pitting, thread damage or seepage around the hull penetration. A fresh bronze body and nut restore a watertight seal without changing the hull cutout. California Proposition 65 warnings apply to chemicals in the product.

Suits Bronze-Preferred Installations

This fitting suits owners and yards specifying bronze for thru-hull applications where material compatibility with existing bronze valves or strainers is required. It is not for installations needing a different material such as stainless steel or composite, nor for hull thicknesses outside the nut’s adjustment range. Buyers needing a different flange style or thread pattern should look elsewhere.

Questions about this item

What hull thickness range does the 2-inch TH-200-W bronze thru-hull accommodate?

The TH-200-W is designed for standard hull thicknesses encountered on recreational craft; its threaded shank allows secure engagement with the supplied nut once the correct hole is cut.

Which installation step is most often missed when fitting the Groco TH-200-W?

Applying a marine-grade sealant to both the flange and the nut faces before tightening prevents water ingress and galvanic corrosion between the bronze and the hull.

How often should the bronze thru-hull and its nut be inspected or replaced?

Inspect the TH-200-W annually for dezincification, cracking or nut loosening; replace the fitting if pink discolouration or thread damage appears.
