Professional Applications & Engineering Value
This galvanized iron reducer nipple solves critical piping transition challenges in industrial systems requiring pressure-rated connections between different pipe sizes. The seamless construction combined with NPT threading creates a robust, leak-resistant junction that maintains system integrity when transitioning from 2 1/2" to 1 1/4" pipelines. Engineered for Class 300 service, it withstands the mechanical stresses encountered in compressed air systems, hydraulic oil lines, steam distribution, and water processing applications. The galvanized surface treatment provides essential corrosion protection in humid or chemically aggressive environments, while the Schedule 80 wall thickness ensures dimensional stability under cyclic pressure loading.
Specification Summary & Compliance
This reducer nipple features precision NPT threads per ASME B1.20.1 with dimensional compliance to Schedule 80 specifications. Manufacturing follows ASTM A234 for wrought carbon steel fittings and ASTM B633 for zinc coating requirements, with additional conformance to MSS SP-95 for reducing nipples. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, containing no substances of very high concern above threshold limits.
