TonGass 3 Inch RV Waste Valve with 72 Inch Cable — Cable-Actuated Bulkhead Folding T-Handle

TonGass 3-inch cable-actuated RV waste valve kit gives you remote control of your black tank termination with a 72-inch cable and bulkhead folding T-handle for easier, cleaner dumping.

This heavy-duty kit replaces or upgrades a manual termination valve on RV black water systems. The 3" valve body fits standard RV waste lines while the 72" stainless-style cable lets you mount the operating handle in a more convenient or protected location. The fold-flat T-handle is bulkhead-ready and the cable-actuated design reduces awkward reaches, helping you open and close the valve with more control and less mess.

How does a cable-actuated valve improve RV dumping?

A cable-actuated termination valve separates the operating handle from the valve body, so you can locate the handle where it’s easy to reach while the valve stays protected behind a compartment or down low. This reduces the need to crouch or reach into tight service bays and helps keep the valve area cleaner because you’re not constantly handling the valve itself.

• Remote control with a 72" cable for flexible handle placement.
• Folding T-handle mounts on a bulkhead or sidewall for convenience.
• Smoother open/close when cable routed with gentle bends and clamps.
• 3" valve body matches common RV black tank termination lines.

Will this kit fit my RV’s existing 3-inch waste line?

The TonGass kit is built for standard 3" termination connections commonly used on RV black tanks. It’s designed to work as a direct replacement for many OEM valves or as an upgrade when the original handle is hard to reach or damaged. Check your valve flange or termination measurements to confirm compatibility before installation.

• 3" valve body sized for typical RV waste plumbing.
• Bulkhead fold-down handle fits common service bay layouts.
• Cable length accommodates most coach plumbing runs up to 72".
• Works for repairs or aftermarket upgrades; verify flange details.

How should I route and secure the 72-inch cable for best operation?

Proper routing ensures reliable, low-friction operation and a long service life. Run the cable with broad, gradual curves and secure it every 18–24 inches to reduce movement and prevent binding against sharp edges. Avoid tight bends and places where debris can wear the cable housing.

• Use gentle bends; avoid 90-degree turns in the cable path.
• Fasten cable housing every 18–24" with clamps or cable ties.
• Protect exposed sections from chafing against metal edges.
• Check action after installation and adjust stops for full open/close travel.

What does the folding T-handle offer for bulkhead mounting?

The fold-down T-handle mounts on a bulkhead or compartment wall and tucks flat when not in use, saving space and preventing accidental snags. Its shape provides good leverage for opening and closing the valve, and the folding feature keeps the handle from protruding into walkways or storage areas.

• Folds flat to minimize interference in service bays.
• T-handle shape gives improved grip and leverage.
• Bulkhead-ready mounting hardware for quick installation.
• Durable finish resists weather and road grime exposure.

Who this is for: RV owners, fleet managers, or technicians who need a reliable 3" termination valve with remote operation for safer, cleaner black tank dumping. It’s ideal for coaches where the OEM handle is hard to reach, for retrofits that improve ergonomics, or for replacing worn valves. If you want a robust, bulkhead-mountable valve with a long cable run and a folding handle for compact storage, this TonGass kit is built for those needs.
