Product identity

The Legend Valve 311-173 is a 2" x 9" brass nipple coupling intended for plumbing installations. It serves installers and maintenance teams who need a straight pipe section with male threads on both ends. The fitting is supplied new and carries a California Proposition 65 warning for chemicals linked to cancer and reproductive harm.

Thermal and acoustic profile

This component has no moving parts and draws no power, so it produces no heat or noise during normal operation. System thermals and acoustics are determined entirely by the surrounding pipework, pumps and fluid temperature. No fan, radiator or power supply figures apply to this fitting.

Decisive specification

The critical detail is the 2" nominal diameter combined with a 9" overall length in no-lead red brass. Only buyers whose piping matches both dimensions and material requirement should select this part; those needing a different bore, length or alloy must choose another fitting.

Highlights

  • No-lead brass reduces health risk
  • 2-inch by 9-inch size fits standard plumbing
  • Legend Valve 311-173 model ensures compatibility
  • Brass construction resists corrosion
  • New condition guarantees full service life

Questions about this item

How do I install the 2" x 9" brass nipple coupling without damaging the threads?

Apply pipe thread sealant or tape to the male threads, hand-tighten the nipple into the fitting, then finish with a wrench — overtightening is the common mistake that cracks the brass.

What maintenance will the 311-173 brass nipple need over time?

Inspect the joint periodically for green corrosion or seepage; reapply thread sealant if a leak develops, otherwise no routine servicing is required.

What is the first limit that appears when the 311-173 nipple is under sustained pressure?

The brass material will deform or leak at the threads before the coupling body fails, so thread integrity is the limiting factor.
