Asc Engineered Solutions 8700139606 Black Iron Close Nipple

Product Description

The ASC Engineered Solutions 8700139606 is a close-pattern black iron pipe nipple designed for threaded pipe assemblies in gas, steam, and water distribution systems. Manufactured from welded steel with a black iron coating, it meets ASTM A53 standards for structural and pressure service. The close-length configuration positions two threaded ends with minimal exposed barrel, making it the right choice when a standard-length nipple would create unwanted spacing in a fitting-to-fitting connection. Licensed plumbers and pipefitters install this nipple wherever a tight inline connection is required between two threaded fittings.

This nipple is suited for residential and light commercial plumbing, gas distribution, and hydronic heating applications. Its Schedule 40 wall thickness handles standard system pressures across a range of pipe uses. The close configuration is especially common in gas piping manifolds, boiler trim piping, and compressed air headers where back-to-back fittings need a secure, rigid metal-to-metal transition without extra standoff length.

Key Features

• Close-length configuration for fitting-to-fitting connections with minimal exposed pipe
• Black iron coating provides corrosion resistance for interior and protected installations
• Meets ASTM A53 standards for welded steel pipe in pressure and structural service
• Schedule 40 wall thickness for standard working pressures
• Standard NPT threads for compatibility with common threaded pipe fittings

Compatibility

Designed as an OEM-style replacement or standard-stock close nipple for 3/4 inch Schedule 40 threaded pipe systems using NPT fittings in plumbing, gas, or hydronic applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Fuel Gas Code or International Plumbing Code where relevant. Apply an approved thread sealant or PTFE tape rated for the service medium before making up threaded joints. Tighten to a snug, wrench-tight fit using a pipe wrench — do not overtighten, as this can crack adjacent cast fittings. Pressure-test the assembly before returning the system to service.
