Sierra POLYX Sanitation Hose, 3/4 in ID, 50 ft Coil
Sierra POLYX Sanitation Hose, 3/4 in ID, 50 ft Coil — Product description
Sierra's POLYX sanitation hose is the 3/4-inch line that runs your head to the holding tank and the tank out to the pump-out fitting. Black reinforced rubber, 50 feet on the coil, built to shrug off the odor and pump pressure that come with marine sanitation duty.
If you've ever re-plumbed a marine head, you know sanitation hose isn't the place to cut corners. This is Sierra's POLYX hose in the 3/4-inch inside diameter size, the run that carries waste from the head to the holding tank and from the tank out through the deck pump-out fitting. It's reinforced rubber, so it holds its shape under pump pressure and doesn't kink where it bends around a bulkhead.
The 50-foot coil gives you plenty to work with. Most head installs need more hose than you'd think once you account for the loops, the vented loop, and the runs through tight lockers. Cut what you need and keep the rest for the next job.
Odor permeation is the thing that sinks a cheap sanitation line. The reinforced rubber wall here is built to keep smells in the hose where they belong, not seeping into the cabin. Outside diameter is 1-7/16 inches, so double-clamp it at every fitting with proper stainless hose clamps and you're set. Black, so it disappears behind the liner.

Frequently asked questions
What's this hose used for?
It runs from the marine head to the holding tank, and from the holding tank out to the deck pump-out fitting. Those are the two main sanitation runs on most boats.
What size fittings does it fit?
The inside diameter is 3/4 inch, so it slips over standard 3/4-inch sanitation barbs and thru-hull fittings. Outside diameter is 1-7/16 inches. Double-clamp every connection with stainless clamps.
How much hose is on the coil?
50 feet. That's typically enough for a complete head-to-holding-tank and pump-out plumbing job with some left over.
Will it help keep odor out of the cabin?
The reinforced rubber wall is built to limit odor permeation, which is the usual culprit behind a smelly cabin. Pair it with a properly vented holding tank for the best results.
Is it stiff to route?
It's reinforced rubber, so it holds pressure without collapsing but still bends around bulkheads and into lockers. Warming a coil in the sun makes tight bends easier to pull.
