TonGass RV Sewer Hose Adapter 2-Pack — 3" Bayonet to 3" Slip Hub, Rotating ABS Hook-fit

TonGass 2 x Combo Pack RV Sewer Hose Fitting Adapter provides two black ABS adapter pieces to link a 3" RV twist-on bayonet outlet to 3" slip-hub pipe or sewer hose connections.

These two-piece adapter kits are made to match common RV waste outlet geometries and pipe sizes, giving you a rotating twist-on connection plus a termination adapter with a 3" female slip hub. Both pieces are molded in black ABS to align with OEM dimensions; use the correct adhesive for the pipe material you attach. The set simplifies joining an RV bayonet-style outlet to glued 3" ABS or fitted sewer hoses without modifying existing fittings.

How does the rotating rigid pipe adapter work with an RV outlet?

The rotating rigid pipe adapter is a 3" standard RV twist-on component fitted with bayonet hooks that locks onto the RV’s waste outlet. Its rotating design lets you align and engage the bayonet lugs quickly without twisting the entire hose assembly.

• 3" female slip hub mates to standard 3" pipe
• Four bayonet hooks for secure twist-on attachment
• Rotating body helps line up hooks and reduces strain on hose

What is the termination adapter used for when connecting sewer hose?

The termination adapter bridges a sewer hose or cap to a glued 3" slip pipe. One end accepts a 3" twist-on bayonet connector, while the opposite end is a female slip hub sized for 3" ABS or PVC pipe that requires adhesive installation.

• Bayonet lug nub end fits standard RV twist connectors
• Female slip hub accepts 3" ABS/PVC pipe with proper glue
• Hand-installable; designed to integrate with existing hose/cap accessories

Which materials and adhesives should I use with these adapters?

Both pieces are molded from black ABS plastic. When you join the female slip hub to a pipe, match the adhesive to the pipe material: ABS solvent cement for ABS pipe, or the correct PVC cement for PVC pipe. Avoid using a single adhesive for differing plastics to prevent weak bonds or chemical incompatibility.

• Adapter material: black ABS plastic
• Use ABS cement for ABS pipe, PVC cement for PVC pipe
• Dry-fit first, then apply adhesive per manufacturer instructions

Who is this for? This TonGass 2-piece combo pack is intended for RV owners, repair technicians, and DIYers who need a reliable way to join a 3" bayonet-style RV waste outlet to 3" piping or sewer hose systems. It suits anyone replacing worn bayonet fittings, upgrading discharge connections, or adapting hoses to a glued 3" drain line; it’s not a plumbing pressurized-water fitting but a waste outlet connection designed to match common RV standards.
