Bmi Usa 4700 Brass Lead-free Close Nipple 1-1/4 in

Product Description

The BMI USA 4700 is a lead-free brass close nipple designed for threaded pipe assemblies in plumbing, HVAC, and mechanical systems. A close nipple is fully threaded end-to-end with no unthreaded center, allowing two female-threaded fittings to be joined with minimal spacing between them. At 1-1/4 inch nominal pipe size, this nipple handles common supply and return line applications where compact inline connections are required. The lead-free brass construction meets modern potable water standards, making it appropriate for domestic water systems. Licensed plumbers and pipefitters are the primary installers for this type of fitting.

This nipple is suited for residential and light commercial plumbing installations including water supply lines, boiler piping, and hydronic heating systems. Its 1-1/4 inch NPT thread pattern allows direct connection to standard female-threaded valves, couplings, tee fittings, and manifolds. The red finish is a manufacturer identifier and does not affect function. Applications include tight-clearance installations where a standard nipple with a hex center cannot be used.

Key Features

• Lead-free brass construction suitable for potable water service
• 1-1/4 inch nominal pipe size with NPT threads on both ends
• Close (CL) pattern — fully threaded end-to-end, no unthreaded center
• Red finish for manufacturer identification
• Lightweight at 0.25 pounds for easy single-handed installation

Compatibility

Designed as an OEM-style replacement close nipple for standard 1-1/4 inch NPT female-threaded fittings in residential and commercial plumbing and hydronic piping systems.

Installation Notes

Installation is performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the water supply before removing or installing any threaded fitting. Apply thread sealant tape or paste rated for the service fluid before hand-tightening and then wrench-tightening. On close nipples, use an internal pipe wrench or nipple extractor to avoid deforming the threads during removal.
