TonGass 3" Rotating Rigid Bayonet Adapter Kit — 3in Male Thread & Hooks, ABS Durable Seal

The TonGass 3" Rotating Rigid Bayonet Adapter with Male Thread & Hooks is a two-piece RV sewer adapter kit that gives a tight, rotating bayonet connection and a threaded termination for reliable 3-inch sewer hookups.

When managing waste connections on an RV, a precise fit and durable materials matter. This TonGass kit combines a 3-inch rotating bayonet adapter and a threaded termination adapter so you can attach standard camper sewer hose or permanently glue to ABS/PVC plumbing. It’s built to OEM-style dimensions and designed to reduce leaks and simplify hookups at dump stations or permanent drain points.

How does the rotating bayonet adapter make hookups easier?

The rotating bayonet-style adapter lets you align and lock the hose quickly without awkward twisting of the entire assembly. The rotation reduces strain when attaching to an RV outlet and helps ensure the bayonet hooks seat correctly for a stable seal.

• 3" bayonet hooks provide positive engagement with standard RV waste outlets
• Rotating collar allows fine alignment before locking
• Smooth rotation reduces wear on hose and fittings

Can I connect this to my existing camper sewer hose or plumbing pipe?

Yes — the kit includes a threaded termination adapter for coupling to male-threaded plumbing or to a camper sewer hose with a matching 3-inch thread. For permanent installations into ABS or PVC pipe, use the appropriate solvent weld glue recommended for sewer applications.

• Male-threaded termination fits standard 3" plumbing threads
• Compatible with common camper sewer hose couplings
• Glue-ready ABS body for secure, long-lasting pipe bonds

What materials and construction ensure leak resistance?

TonGass builds these adapters from heavy-duty black ABS plastic molded to OEM-style tolerances, providing a stiff, durable connection that resists cracking. The design uses four bayonet hooks and a twist-on connector to create a tight mechanical seal; for glued joints, proper solvent cement achieves a permanent, watertight bond.

• Durable ABS construction resists impacts and UV exposure
• Four-bayonet-hook locking geometry for a snug seal
• Designed for correct glue application to ABS/PVC pipe

Is installation complicated for occasional RV users?

Installation is straightforward: rotate-and-lock for the bayonet adapter or apply solvent cement for a permanent termination. No specialized tools are required for the bayonet hookup; gluing the termination adapter requires common plumbing solvent and basic cutting/measuring tools.

• Bayonet connection engages without tools
• Termination adapter installs with standard pipe glue and basic tools
• Clear OEM-style dimensions make alignment predictable

Who is this for: RV owners, campground maintenance crews, and DIYers who need a dependable 3-inch sewer fitting that balances quick-connect convenience with the option for a glued, permanent termination. If you want an OEM-sized, durable ABS adapter set that reduces leaks and simplifies waste hookups, the TonGass rotating bayonet and termination adapters provide a practical, long-lasting solution.
