Rule Replacement Garden Hose Adapter

The Rule Replacement Garden Hose Adapter is an essential accessory for marine and automotive water system maintenance. Whether you're managing bilge pump discharge, engine cooling loops, or portable water transfer operations, this adapter bridges the gap between Rule's industry-standard fittings and standard garden hose connections. Built for reliability in demanding environments, it eliminates the need for improvised solutions and ensures leak-free, secure connections every time you service your vessel or vehicle's water systems.

Engineered as a direct replacement component for Rule's pump and plumbing systems, this adapter features machined threads that mate precisely with Rule's threaded outlets while accommodating standard 5/8-inch or 3/4-inch garden hose barbs. The compact design—measuring just 3 x 2 x 6 inches and weighing only 0.1 lbs—makes it easy to store aboard or in your vehicle's utility kit. Durable construction resists corrosion from saltwater and freshwater exposure, maintaining watertight integrity across temperature fluctuations and pressure cycles typical of marine and mobile applications.

Technicians and boat owners benefit most from having replacement adapters on hand, as worn or damaged fittings can compromise entire water transfer systems. Installation is straightforward—hand-thread onto your Rule pump or plumbing outlet, then secure your garden hose with a stainless-steel hose clamp. This adapter is compatible with all Rule electric and manual pump models featuring standard metric or SAE threaded ports, making it an indispensable spare for anyone maintaining backup systems, emergency bilge operations, or seasonal winterization procedures. Keep one in your tool kit for peace of mind during extended cruising or remote mobile work.
