1/2 inch x 2-1/2 inch Chrome-Plated Brass Nipple

1/2" x 2-1/2" Lead-Free Brass Nipple – MIP x MIP, Potable Water Rated

The 1/2" x 2-1/2" Lead-Free Brass Nipple is a straight pipe fitting used to connect two female-threaded components in potable water, air, or non-corrosive fluid systems. Featuring male National Pipe Tapered (NPT) threads on both ends, this fitting is precision-machined for secure engagement and pressure retention in both residential and commercial installations.

Manufactured from lead-free brass in compliance with NSF/ANSI 61 and 372, this nipple is approved for use in drinking water applications. It resists dezincification and corrosion under typical service conditions and is suitable for hot and cold water systems, including municipal water lines, pressure booster systems, and hydronic distribution loops.

Key Product Features

• ✅ Material: Lead-free brass (≤0.25% Pb), compliant with Safe Drinking Water Act
• ✅ Thread Standard: ANSI/ASME B1.20.1 NPT – ensures thread compatibility with standard fittings
• ✅ Size: 1/2" nominal diameter, 2-1/2" overall length
• ✅ Operating Pressure: Suitable for systems up to 200 PSI under typical water supply conditions
• ✅ Corrosion Resistance: Brass composition offers long-term resistance to scale, pitting, and mineral buildup

Installation Guidelines

Apply PTFE tape or thread sealant to male threads before insertion into mating fittings. Use a wrench on the flats to tighten, avoiding excessive torque to maintain thread integrity. Suitable for use in copper, CPVC, or PEX-to-metal transitions when installed with compatible adapters and fittings. All installations should comply with applicable plumbing codes and pressure guidelines.

Common Applications

This brass nipple is used in potable water systems, water heater connections, pressure tanks, irrigation setups, and general plumbing assemblies requiring short-span threaded connections. It supports use in new construction, repair work, and system modifications.

Compliance Note

Certified under NSF/ANSI 61 and 372, this fitting meets federal and state requirements for lead-free components in potable water systems. It is approved for use in jurisdictions adhering to SDWA mandates.
