8 inch no hub coupling

The Legend Valve 303-414 connects two 8 inch no hub pipe ends in drainage waste and vent systems. It is intended for professional plumbers and maintenance teams working on commercial or residential soil stacks. The coupling joins cast iron, plastic or steel pipe without the need for hub fittings.

Replaces hub and spigot joints

This coupling removes the requirement for traditional hub connections on 8 inch lines, reducing material cost and assembly time. The switch is worthwhile when the installer prefers a shielded rubber gasket and stainless steel clamp arrangement over oakum and lead or compression gaskets. It suits retrofit projects where hub fittings are unavailable or impractical.

Slip on and tighten clamps

Installation consists of sliding the coupling over the pipe ends and tightening the included clamps to the recommended torque. Common issues include leaks from misaligned pipe ends, insufficient clamp torque or debris on the gasket seating surface. The product carries a California Proposition 65 warning for chemicals known to cause cancer and birth defects or other reproductive harm.

Questions about this item

What pipe diameter does the 8 inch no hub coupling join?

The Legend Valve 303-414 couples two 8 inch no hub pipes or fittings with a stainless steel clamp and gasket seal.

How do I install the coupling and what step is often missed?

Slide the coupling over the pipe ends, centre the gasket on the joint, then tighten the clamp bolts evenly to the specified torque; skipping the torque step causes leaks.

When should I replace the gasket or clamp on this coupling?

Inspect the gasket for cracking or hardening and the clamp for corrosion every year; replace either part at the first sign of wear to maintain a watertight seal.
