Aussio RV Sink Drain Kit — Flexible 25-inch Hose, 1-1/2-inch Threaded Drain & ABS Flange

The Aussio Flexible RV Sink Drain Kit is a complete single-sink wastewater evacuation system that includes a 25" flexible hose, 1-1/2" threaded drain fitting compatibility, an ABS evacuation flange with cap, and a chemical-resistant trap for reliable gray-water routing in campers and trailers.

If you need a compact, serviceable drain assembly for an RV, pop-up, camper or outdoor galley without a holding tank, this kit replaces worn parts or completes a new sink install. It’s built to match common RV drain sizes, fit into tight under-sink spaces, and resist household detergents and gray water so you can get consistent drainage on the road or at the campsite.

How does this kit fit my RV sink?

The evacuation flange accepts the standard 1 1/2"-11 1/2 threaded drain fittings used in most RV galley basins, making it compatible with many OEM and aftermarket sinks. The package is designed for single-sink layouts commonly found in trailers and small campers.

• 1 1/2" threaded drain fitting acceptance for broad compatibility
• Evacuation flange shaped for compact RV cutouts
• Intended for single-sink systems and no-holding-tank setups

Will the 25" hose route easily under my sink?

The flexible 25" length and 3/4" ID hose offer extra routing options compared with rigid piping, helping you avoid obstacles and line up with an external discharge or camper-side drain. Its supple construction reduces stress at connection points and helps prevent kinks that impede flow.

• 25-inch flexible hose for maneuvering in tight spaces
• 3/4" inner diameter that balances flow and compact routing
• Flexible material reduces strain and potential leak points

How durable and chemical-resistant are the components?

The kit combines a chemical-resistant polymer trap with a molded ABS evacuation flange and cap, materials selected to resist common cleaning agents and the acidity of typical gray water. They’re engineered to stay leak-free and crack-resistant under normal camper use and temperature changes encountered on the road.

• Chemical-defiant polymer trap resists detergents and soaps
• ABS flange and cap resist impact and weathering
• Materials chosen to minimize cracking, swelling, and leaks

Is installation something I can do myself?

Yes — the Aussio kit is designed for straightforward DIY installation using common household tools. Clear threaded connections and a compact hose make it a practical upgrade or repair option without specialized plumbing experience.

• Threaded 1 1/2" fittings simplify attachment to many sinks
• Push-fit style hose routing and clamps reduce complexity
• Ideal for quick on-site repairs or upgrades in the field

Who is this for: The Aussio Flexible RV Sink Drain Kit is aimed at camper owners, trailer DIYers, RV technicians and weekend van-builders who need a reliable single-sink drainage solution without a holding tank. It’s a practical choice if you want a universal-fit replacement, easier hose routing beneath compact galley sinks, or a durable set of components that tolerate routine cleaning agents and gray-water use.
