Professional Applications & Engineering Value
This black-coated steel pipe nipple with dual right-hand and left-hand NPT threads solves critical installation challenges in industrial piping systems. The welded construction combined with Schedule 40 wall thickness provides exceptional burst resistance when handling compressed air, natural gas distribution, hydraulic oil lines, steam transfer, and water systems. Engineers specify this component for its ability to create secure connections between iron and steel fittings while accommodating space constraints through its reverse-threading capability. The black coating extends service life in corrosive environments, making it ideal for chemical plants, manufacturing facilities, and utility infrastructure where reliability is paramount.
Specification Summary & Compliance
This 4" long pipe nipple features precise NPT threads on both ends manufactured to ASME B1.20.1 standards for guaranteed interchangeability. The component meets ASTM A53 and ASTM A733 material specifications with Schedule 40 dimensions (0.622" ID, 27/32" OD, 0.109" wall thickness). Compliance with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) regulations ensures environmental safety and restricted substance control for global industrial applications.
