Professional Applications & Engineering Value
This black-coated steel pipe nipple solves critical installation challenges in industrial fluid systems through its innovative right-hand and left-hand threaded design. The welded construction combined with Schedule 40 wall thickness provides exceptional burst pressure resistance when handling compressed air, natural gas distribution, hydraulic oil lines, steam systems, and water pipelines. The NPT thread standard ensures perfect sealing with Class 125 and 150 iron/steel fittings, eliminating leakage risks in high-vibration environments. Manufacturers benefit from the dual-thread configuration which significantly reduces installation time in tight spaces where full pipe rotation is impossible, making it ideal for maintenance, repair, and retrofit applications across chemical plants, manufacturing facilities, and energy infrastructure.
Specification Summary & Compliance
This 3/8" NPT threaded pipe nipple maintains precision ASME B1.20.1 thread standards with dimensional compliance to ASTM A53 and ASTM A733 specifications. The product features consistent 0.493" ID and 43/64" OD dimensions with 0.091" wall thickness throughout its 4" length. Manufacturing and material composition fully comply with RoHS 3 (2015/863/EU) restrictions and REACH (EC 1907/2006) substance regulations, ensuring environmental responsibility and global market acceptance.
