TonGass RV Sewer Hose Adapters 2-Pack — 3" Bayonet Twist-On + 3" Slip Hub, ABS with Thread Seal Tape

TonGass 2 x Combo Pack delivers two 3" RV sewer hose adapters — a rotating rigid pipe adapter and a termination adapter — engineered to connect a RV waste outlet to 3" ABS/PVC sewer pipe or hose securely.

This dual adapter kit provides the common connectors RV owners and service technicians need for reliable waste-line hookups. Each black ABS component is built to OEM dimensions: one rotating twist-on adapter with bayonet hooks to mate with RV outlets and one termination adapter with a 3" slip hub for glued pipe connections. The set includes thread seal tape and is intended for use where ABS or PVC sewer piping meets your RV sewer connection.

How does the rotating rigid pipe adapter make RV hookups faster?

The rotating rigid pipe adapter lets you attach and twist into place quickly without having to realign rigid piping. Its 3" twist-on interface and four bayonet hooks match standard RV outlets, reducing time and fumbling while securing the waste line connection.

• 3" female slip hub mates to glued pipe or fittings.
• Four bayonet hooks align with common RV twist-on outlets.
• Rotating section eases insertion and final twist lock.
• Black ABS construction resists typical campsite wear.

What is the termination adapter used for in an RV sewer setup?

The termination adapter bridges a sewer hose or cap to a glued 3" ABS/PVC drain line. One end accepts a 3" twist-on connector with bayonet nubs for hose or cap attachment, while the other end is a 3" female slip hub designed for solvent welding to ABS or PVC pipe.

• Female slip hub built for glue connection to 3" pipe.
• Bayonet nub end supports standard twist-on sewer hose fittings.
• Works as a termination point at dump stations or permanent sewer tie-ins.
• Packaged as a matched pair for both inlet and outlet needs.

Can I use these adapters with ABS and PVC pipes safely?

The adapters are molded from black ABS plastic and are sized to meet typical RV sewer fittings. When attaching to ABS pipe, use ABS-compatible solvent cement; when attaching to PVC, use the correct PVC primer and cement or a suitable transition method to ensure a proper seal.

• Adapter material: black ABS — follow ABS glue instructions.
• Use appropriate primer/cement for PVC if joining PVC pipe.
• Thread seal tape is included for threaded connections to improve sealing.
• Avoid mismatched solvents; follow manufacturer bonding guidelines.

What installation tips help avoid leaks and failures?

Prep mating surfaces, confirm fit, and use the correct adhesive for the pipe material. Hand-tighten the twist-on bayonet until it seats, then perform a visual check for gaps; allow glued joints to cure fully before testing flow.

• Clean and dry slip hubs before applying solvent cement.
• Wrap male threaded fittings with included thread seal tape as needed.
• Rotate the bayonet adapter to ensure a positive mechanical lock.
• Let solvent-welded joints cure per adhesive manufacturer instructions.

Who this is for: RV owners, campground maintenance crews, mobile-home service technicians, and DIYers who need a compact, OEM-sized solution to connect RV waste outlets to standard 3" sewer pipe or hose. The TonGass combo pack is geared toward anyone replacing worn connectors, building a permanent RV sewer tie-in, or keeping spare adapters in a service kit for seasonal travel.
