Jabsco Flush Mount Hose Adapter, 3/4 in GHT Male, Built-In Check Valve

Overview

The Jabsco 31911-0002 is a flush-mount hose adapter for a deck washdown connection on boats. It uses a 3/4" GHT male hose thread and twists into the matching flush deck fitting, so you can connect a washdown hose without leaving a hose bib and knob sticking up on deck.

This adapter is the hose-side piece, not the full deck fitting assembly. It is a practical match for washdown points near the anchor windlass, cockpit, or side decks where quick hose access matters and a clean deck layout is easier to live with day to day. The pre-installed check valve allows connection with the system under pressure, which helps when the washdown pump and plumbing are already live.

Key features

• 3/4" GHT male hose connection for washdown hoses and HoseCoil setups
• Quick twist-on connection to the matching flush deck fitting
• Pre-installed check valve for connection while the line is pressurized
• Flush arrangement helps keep the deck clear when the hose is not in use
• Useful for washdown stations near anchors, foredecks, cockpits, and boarding areas

Compatibility and fit

This part is intended to work with the Jabsco flush-mount deck washdown fitting system. Before ordering, it is worth checking that your boat already has the matching Jabsco deck fitting or that you are building around that fitting style, since this adapter is the piece that twists into the deck outlet and presents the 3/4" GHT hose connection.

For buyers replacing a worn adapter, the main fit point to confirm is the hose side connection. The 3/4" GHT thread suits common washdown hose arrangements, which makes it straightforward to keep a hose stored separately and only connect it when the job calls for it.

Use on board

This adapter makes the most sense on boats that need a ready washdown point but do not want a hose permanently cluttering the deck. It suits crews who rinse muddy anchors, salt off the foredeck after a run, or want faster cleanup around the cockpit after fishing or a day at the dock.

In a pressure-fed washdown setup, it keeps hose hookup simple and quick. That is especially useful when the washdown point is exposed and you want the outlet to stay low-profile until the hose is actually needed.

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.
