Legend Valve 303-423 6 inch Coupling

The Legend Valve 303-423 is a heavy duty no hub coupling built for joining pipe sections in plumbing installations. It suits professionals and DIY users who need a reliable mechanical joint without the use of hub fittings. The component is supplied new and ready for immediate installation.

Sustained sealing under pressure

The coupling maintains a consistent seal when subjected to continuous fluid pressure and vibration in drainage or vent systems. Its heavy duty construction resists deformation during prolonged service cycles. The design accommodates thermal expansion and ground movement without losing joint integrity over time.

Verify pipe compatibility and regulations

Confirm that the existing pipe material and outside diameter match the coupling's 6 inch nominal size before ordering. Check local plumbing codes for approval of no hub couplings in the intended application. Note the California Proposition 65 warning regarding chemicals known to cause cancer and reproductive harm.

Questions about this item

Does the 303-423 coupling generate any noise or heat when installed in a continuously running drainage system?

The coupling is a passive mechanical joint with no moving parts, so it produces no operational noise or heat once installed.

What pipe material and tools must I already have to install the 6 inch no-hub coupling?

You need matching 6 inch no-hub pipe or fittings and a torque wrench or socket set to tighten the stainless-steel clamps to the specified torque.

Will the 303-423 couple directly to older cast-iron soil pipe that is still in place?

Yes, the no-hub design is made to join hubless cast-iron, plastic or steel pipe of the same nominal size without special adapters.
