Perko Thru-Hull Connection for Hose, White Plastic, Broad Flange

Overview

The Perko 0328 is a molded white polymer thru-hull connection for use with hose on above-waterline marine plumbing runs. It uses a broad flange and is offered in hose sizes from 1/2 inch to 1-1/2 inches, with matching mounting hole and maximum hull thickness dimensions for each size.

This fitting is a practical choice for hose discharge points where a plastic thru-hull is appropriate, such as many bilge pump outlets, livewell drains, sink drains, and other topside or transom plumbing locations. It is not recommended for use below the waterline, so placement and hull penetration location should be checked before installation.

Key features

• Molded white polymer construction helps avoid corrosion concerns on suitable above-waterline installations.
• Broad flange gives the fitting a larger bearing surface at the hull exterior.
• Available hose sizes cover common small-boat plumbing needs from 1/2 inch through 1-1/2 inches.
• Each size is matched to a specific mounting hole diameter and maximum hull thickness for cleaner fit planning.
• Threaded body accepts a flanged nut for securing the fitting from inside the hull.
• Not recommended for below-waterline use, which makes installation location an important part of product selection.

Variants

The range varies by hose size, mounting hole diameter, and maximum hull thickness. The smallest sizes use a 13/16 inch mounting hole and support hull thickness up to 1-1/4 inches, while the largest 1-1/2 inch hose version uses a 1-7/8 inch mounting hole and supports hull thickness up to 1-7/8 inches.

Across the listed configurations, the product remains a white plastic thru-hull connection for use with hose and a broad flange. Match the variant to the inside diameter of the hose and verify the hull thickness at the planned installation point before cutting the mounting hole.

Installation and fit

Before installation, confirm that the hose size, mounting hole diameter, and hull thickness match the selected configuration. A clean, properly sized hole helps the threaded body seat correctly, while the broad flange should sit flat against the outside surface of the hull.

Use a marine sealant suitable for the hull material and the installation area, and tighten the retaining nut from inside the boat without distorting the fitting. Hose routing should allow a smooth bend where possible, with clamps placed so the hose is held securely without stressing the thru-hull.

Use on board

This fitting suits boat owners replacing a worn plastic thru-hull or setting up a new above-waterline hose outlet where a white exterior finish matches the hull or transom. It is most useful on small boats, center consoles, runabouts, sailboats, and fishing boats with straightforward hose plumbing that does not pass below the waterline.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
