Perko 1-1/4" Thru-Hull Fitting f/Hose Bronze MADE IN THE USA

The Perko 1-1/4" Thru-Hull Fitting for Hose is the backbone of any serious marine plumbing system, whether you're running a through-hull drain, raw water intake, or bilge discharge on your boat. After years on the water, you learn that thru-hull fittings are not something to compromise on—they're the critical interface between your boat's interior and the outside environment, and failure can mean catastrophic water intrusion. This bronze fitting from Perko is built to handle the corrosive marine environment and the constant pressure cycling that comes with saltwater and freshwater use.

Bronze construction resists galvanic corrosion far better than standard brass or aluminum, making it the material of choice for hull penetrations in saltwater applications. The 1-1/4" diameter accommodates standard marine hose sizes commonly used in engine cooling loops, waste systems, and livewell plumbing. The fitting's design creates a secure, watertight seal when properly installed with backing washers and sealant, and it accepts hose with barbed connections that won't slip under pressure. Perko's manufacturing heritage—this fitting is made in the USA—ensures consistency and reliability that matches the exacting standards professional boat builders and retrofit specialists demand.

Whether you're replacing a failed thru-hull during haul-out maintenance, upgrading an older vessel, or building new systems on a custom project, this Perko fitting delivers the durability you need. Installation requires proper hull hole preparation and backing plate support to distribute load and prevent cracking—critical steps that separate a long-lasting repair from a recurring problem. Anglers and boaters who rely on their vessels know that marine-grade bronze components outlast cheaper alternatives by years, especially in saltwater environments where corrosion can compromise lesser materials within a single season.
