The JMF COMPANY 6818716999900 is a 60-piece black nipple assortment pack sized at 1 inch overall length, designed for use in piping systems where close and short nipple connections are required. The black finish indicates a standard black steel construction commonly used in gas distribution, compressed air, and general industrial piping applications. This assortment provides a practical on-hand supply of nipples for service technicians and pipefitters who need varied fitting lengths during installation or repair work without making multiple supply runs.
This assortment is well suited for residential and light commercial gas piping, compressed air distribution, and similar threaded pipe systems. The 1-inch pipe size fits common main and branch line configurations encountered during routine service calls and new installations. Plumbers, pipefitters, and HVAC technicians working with black iron pipe systems will find this multi-piece pack useful for stocking a service vehicle or shop inventory.
Designed as an OEM-style replacement and general-use fitting compatible with standard 1-inch threaded black iron pipe systems in residential and commercial applications.
Installation of black iron nipples should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, including IFGC requirements for gas piping systems. Always shut off the gas supply or depressurize the air line before threading or replacing fittings. Apply appropriate thread sealant rated for the intended service medium before making up connections. Do not overtighten threaded fittings, as this can crack fittings or strip threads.
