- Precision NPT threads on both male ends guarantee secure, leak-free connections compatible with Class 125 and 150 iron/steel fittings.
- Schedule 40 rating and standard-wall design offer optimal pressure handling and dimensional stability for routine industrial use.
- 20-inch length with straight design enables flexible installation in tight or extended pipeline configurations.
- Full compliance with ASME, ASTM, REACH, and RoHS 3 ensures material safety, performance reliability, and regulatory acceptance.
- Consistent 0.364" ID and 0.088" wall thickness maintain flow efficiency and structural integrity across various system demands.
Professional Applications & Engineering Value
This black-coated steel threaded pipe nipple is engineered to address common industrial challenges such as fluid leakage, corrosion under insulation, and connection failure in volatile media. The welded construction and NPT threading create a robust seal that withstands thermal expansion and vibration in air, natural gas, oil, steam, and water systems. Its Schedule 40 wall thickness and steel material provide the necessary burst resistance and fatigue life for continuous operation in plumbing, HVAC, and process piping. By integrating ASME B1.20.1 thread standards and ASTM A53/A733 material specs, this nipple eliminates compatibility issues and reduces maintenance downtime in industrial pipe fittings networks.
Specification Summary & Compliance
This product adheres to ASME B1.20.1 for NPT threads with Class 2A tolerance, ensuring precise fit with iron and steel fittings rated for Class 125 and 150 service. Manufacturing follows ASTM A53 (material) and ASTM A733 (welded construction) specifications. It is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) directives, confirming the absence of restricted hazardous substances. Key dimensions include 1/4" NPT thread size, 20" length, 0.364" ID, 35/64" OD, and 0.088" wall thickness per Schedule 40 requirements.
