TonGass 3" Rotating Rigid Bayonet Adapter Kit — 3" twist-on with bayonet hooks, ABS rotating collar

The TonGass 3" Rotating Rigid Bayonet Adapter kit is a two-piece RV waste outlet solution that gives a secure, twist-on 3-inch connection with bayonet hooks and a termination adapter for hose or pipe hookups.

This compact combo offers a rotating rigid pipe adapter plus a termination adapter made to OEM dimensions, designed to simplify connections between your RV waste outlet, sewer hose and 3" plumbing pipe. Built from durable black ABS plastic, the pair lets you create a leak-resistant join when bonded with the appropriate solvent cement for ABS or PVC. The rotating feature and bayonet hooks make alignment and sealing faster at campsites or during drain setup.

How does the rotating adapter speed up hookup and alignment?

The rotating rigid adapter reduces fumbling by allowing the adapter body to turn independently while the bayonet hooks engage the outlet. That means you can align a hose or pipe without twisting the entire assembly or repositioning the RV. Rotation helps achieve a snug seating and reduces stress on the connection during insertion.

• 3" twist-on bayonet hooks for fast engagement
• Rotating collar to ease alignment and reduce strain
• Standard OEM sizing for broad compatibility with RV outlets

Can this termination adapter connect both sewer hoses and threaded plumbing?

Yes — the termination adapter is designed with dual-purpose ends: a 3" twist-on with bayonet hooks on one side and a mating end that accepts a standard bayonet connection to a 3" threaded pipe or camper sewer hose. This versatility lets you transition between hose and permanent pipework without extra parts.

• One end: 3" twist-on connector with bayonet lugs
• Other end: standard bayonet-compatible outlet for hoses or threaded pipe
• Useful for temporary hose hookups or semi-permanent pipe connections

What materials and installation steps ensure a reliable, leak-free join?

The adapters are molded from sturdy black ABS plastic to withstand typical RV waste handling conditions. To secure a dependable, long-lasting seal, match the solvent cement to the pipe material: use ABS cement for ABS pipe and the correct PVC primer/cement if joining to PVC. Mechanical engagement with the bayonet hooks plus proper gluing eliminates wobble and reduces leaks.

• Construction: durable black ABS plastic for resilience
• Glue: use ABS solvent for ABS pipe; use appropriate PVC adhesive for PVC
• Fastening: four bayonet hooks/lug nubs for stable twist-on locking

How do I confirm compatibility with my RV waste outlet and sewer hose?

Check that your outlet or hose uses the 3" standard twist-on bayonet style; the TonGass kit follows common OEM dimensions for twist-on connections. Measure the outlet diameter and inspect for bayonet lug slots — if they match, the adapter will seat and lock correctly. The rotating action helps if alignment is slightly off.

• Measure outlet diameter to confirm 3" standard sizing
• Inspect for bayonet lug slots on your existing outlet or hose
• Use the rotation to correct minor misalignment during hookup

Who is this for: This TonGass kit suits RV owners, campground maintenance staff and DIYers who need a reliable 3" connection between an RV waste outlet, sewer hose and a 3" plumbing pipe. It’s ideal for anyone wanting a faster, more secure hookup with reduced stress on fittings and a simple way to adapt hose-to-pipe transitions. Professionals and hobbyists who glue ABS or PVC plumbing will appreciate the OEM-fit dimensions and bayonet locking system for routine waste management tasks.
