Keep your fresh water hose sanitary and road-ready between uses. The Aqua Pro 27917 cap and strap set fits standard 3/4 inch RV drinking water hoses, snapping securely over the hose end to block dirt, insects, road grime, and campground contaminants from getting inside your potable water supply line. Small, lightweight, and easy to lose -- which is exactly why the integrated strap keeps the cap tethered to the hose at all times.
Every RV owner has set a hose end down in a wet gravel pad or left a connection open while breaking camp. That single moment of contact can introduce bacteria and debris directly into your fresh water hose -- and eventually into your tank and faucets. The Aqua Pro 27917 cap-and-strap combo is the simple, inexpensive fix that keeps your hose end capped every time it is disconnected, without any fumbling around looking for a loose piece.
The attached strap is the key differentiator here. Loose hose caps get dropped in the mud, kicked under the rig, or left on the water pedestal at the last campsite. With the strap looped around the hose body, the cap is always right where you need it when you unhook from the city water connection or roll the hose back up after a tank fill.
Strap keeps the cap attached directly to the hose so it cannot be lost during hookup or breakdown at the campsite.
Sized specifically for standard 3/4 inch drinking water and RV fresh water hoses, the most common diameter used across travel trailers, fifth wheels, and motorhomes.
Blocks dirt, insects, campground debris, and moisture from entering the hose end between uses, protecting your potable water supply.
At just 0.05 lbs and packaged within a 5 x 3 x 1 inch footprint, this cap and strap adds virtually no weight to your gear storage.
NSF and health department guidance for potable water systems consistently calls out open hose ends as a contamination risk. RV fresh water hoses are used close to the ground, in proximity to sewer connections, pets, and general campground traffic. A simple cap is your first line of defense against E. coli, coliform bacteria, and other waterborne pathogens entering your fresh water line.
The cap plugs the female threaded end of the hose (the end that typically connects to the city water inlet or fill port), sealing it off until the next use. The strap attachment point loops over or around the hose body so the cap stays captive even when the hose is coiled and stored in a bumper tube, cargo bay, or hose reel.
The 27917 is designed for the 3/4 inch (interior diameter) drinking water hose that is standard across the overwhelming majority of RV fresh water systems. This covers:
Aqua Pro markets a full line of NSF-rated RV drinking water hoses and accessories, and the 27917 cap and strap is designed to complement those hoses. If you are buying or replacing an Aqua Pro fresh water hose and it did not include a cap, or your original cap was lost, the 27917 is the correct replacement accessory. It also works with Camco, teknor apex, and other major-brand 3/4 inch RV hoses that share the standard GHT end fitting.
