Brass Nipple Trap for Drain Systems

The Legend Valve 311-163 is a 2" x 2-1/2" brass nipple trap designed for plumbing drain installations. It connects piping in residential and commercial waste lines where a durable, corrosion-resistant fitting is required. The no-lead red brass construction meets potable water safety standards for supply and drainage applications. Professional plumbers and maintenance crews use it for reliable joint sealing.

Practical Limits of Threaded Brass Fittings

Threaded brass nipples rely on tapered pipe threads to create a seal, which can loosen over time due to thermal cycling or vibration in drain lines. Proper joint compound or tape is essential to prevent seepage at the connection points. The 2" to 2-1/2" transition size suits specific pipe schedules; mismatched schedules risk thread damage or incomplete engagement. California Proposition 65 warnings indicate the presence of listed chemicals requiring safe handling practices.

Build Quality and Daily Installation Implications

No-lead red brass resists dezincification and corrosion better than standard yellow brass, extending service life in aggressive water conditions. The smooth internal bore minimises debris accumulation that leads to blockages in drain traps. Hexagonal wrench flats allow secure tightening without damaging the fitting surface. Direct manufacturer shipping ensures the component arrives free of distributor handling damage.

Questions about this item

Should I choose the 311-163 or a different size for my plumbing job?

The 311-163 is a 2" x 2-1/2" no-lead red brass nipple; select it when those exact dimensions match your pipe and fitting requirements.

How does the 2" x 2-1/2" brass nipple perform once installed in a real system?

It provides a solid, corrosion-resistant connection between a 2-inch and a 2-1/2-inch threaded fitting in water or gas lines.

What thread standard does the 311-163 use and what does that limit in practice?

It uses standard NPT threads, so it seals only with compatible NPT fittings and cannot join to metric or compression ends without an adapter.
