Sea-Dog Fresh Water Inlet, 316 Stainless Steel, 1/2 Inch FIPT x 3/4 Inch FGHT - 513110-1

The Sea-Dog Fresh Water Inlet (513110-1) provides a fresh water hookup point on a boat's hull, letting you connect a standard garden hose to a pressurized onboard water system while moored at a dock or marina. It uses a standard female swivel hose connector so a hose threads on and off easily, and it comes with a black plastic watertight plug that seals the fitting when it is not connected to shore water, keeping the pipe run protected and free of debris.

The inlet is machined from investment cast 316 stainless steel, a corrosion-resistant alloy chosen for marine hardware that stays exposed to saltwater spray and weather. The pipe connection is 1/2 inch FIPT (female iron pipe thread) on the inboard side and 3/4 inch FGHT (female garden hose thread) on the outboard side, matching common marine plumbing and standard garden hose fittings. It mounts through the hull or deck with a #8 flat head fastener and is installed or removed using a 1/2 inch Allen wrench.

This is deck hardware for the plumbing side of a boat's fresh water system rather than an engine or drivetrain component, so it fits any boat with a pressurized fresh water system and a suitable mounting location, without being tied to a specific engine or hull make.

Frequently Asked Questions

What is the Sea-Dog 513110-1 used for? The Sea-Dog 513110-1 is a fresh water inlet that lets you hook a garden hose to a boat's pressurized fresh water system while docked, so you can fill onboard tanks or run water without using the boat's own pump.

What size hose fitting does this inlet use? It has a standard female swivel hose connector on the outside, with a 1/2 inch FIPT x 3/4 inch FGHT pipe size connecting to the boat's plumbing, so a standard garden hose or shore water hose threads directly on.

What material is the 513110-1 made from? It is machined from investment cast 316 stainless steel, a corrosion-resistant grade commonly used in marine deck hardware that is regularly exposed to saltwater and weather.

Does the fresh water inlet come with a cap or plug? Yes, the Sea-Dog 513110-1 includes a black plastic watertight plug that seals the connector when it is not hooked up to a shore water hose.

What tool do I need to install this fitting? Installation and removal of the 513110-1 fresh water inlet uses a 1/2 inch Allen wrench along with a #8 flat head fastener.

How much does the Sea-Dog fresh water inlet weigh? The 513110-1 weighs 0.45 pounds.

What are the mounting dimensions of the 513110-1? The fitting measures 2-3/4 inches at dimension A, 2-3/8 inches at dimension B, 2-3/16 inches at dimension C, and 1 inch at dimension D, secured with a #8 flat head fastener.

Is this the male or female hose connection? The 513110-1 fresh water inlet has a standard female swivel hose connector, designed to receive a male hose fitting from a garden hose or shore water supply.

What is the difference between this fresh water inlet and Sea-Dog's washdown water outlet? The 513110-1 fresh water inlet has a female swivel hose connector for supplying water into the boat's pressurized system, while Sea-Dog's washdown water outlet is a separate part with a male hose connector for drawing water out to a washdown hose; the two look similar but serve opposite functions and are not interchangeable.

Will this fitting work on any boat? The 513110-1 is deck hardware for a boat's fresh water plumbing and is not tied to a specific engine or hull make, so it fits any boat with a pressurized fresh water system and a suitable mounting location for the 1/2 inch FIPT x 3/4 inch FGHT connection.

Is a shutoff valve needed with this inlet? The fresh water inlet itself is a hose hookup fitting; the dossier does not specify an integrated shutoff, so check your onboard plumbing for a valve if one is needed to regulate flow.
