3/4 inch x 3 inch Brass Nipple

3/4" x 3" Lead-Free Brass Nipple – Threaded Component for Potable and Mechanical Systems

The 3/4" x 3" lead-free brass nipple is engineered to meet the demands of professional-grade installations in potable water, HVAC, and mechanical piping systems. Manufactured from certified low-lead brass, this component ensures compliance with federal safety codes and supports corrosion resistance in both hot and cold water applications.

Its standard NPT threading and uniform construction make it suitable for integration into pressure-rated systems where precision and durability are required. This fitting is frequently used in build-outs requiring code-compliant materials and consistent dimensional tolerances.

Material and Performance Features

• ✅ Certified Lead-Free Brass – Compliant with NSF/ANSI 61 & 372 for potable water contact and meets Safe Drinking Water Act guidelines.
• ✅ Full-Form Threads – Precision-machined tapered male threads for secure connection and minimized risk of leakage.
• ✅ Corrosion Resistance – Resilient in chlorinated domestic water systems and resistant to dezincification.
• ✅ Temperature/Pressure Tolerance – Suitable for standard temperature and pressure ranges in water supply and heating circuits.

Use Cases

• Potable water supply piping in residential and commercial buildings
• Threaded valve and fixture extensions for service access
• Connection points in hydronic heating systems and recirculation loops

Installation Notes

This fitting should be installed using pipe sealant or PTFE tape to ensure leak-free assembly. Confirm engagement using hand-tightening followed by calibrated wrench turns to spec. Proper installation is critical in maintaining system pressure ratings and compliance with local codes.

Regulatory Compliance

All lead-free brass components used in potable systems are required by law in all 50 states. This nipple supports such compliance through its verified composition and tested performance, offering assurance in both new construction and retrofit work.
