Professional Applications & Engineering Value
This 304/304L stainless steel threaded pipe nipple delivers exceptional engineering value in industrial fluid and gas handling systems. The seamless construction combined with NPT threading and integrated PTFE thread sealant addresses critical leakage concerns in compressed air, natural gas distribution, steam lines, and petroleum applications. Its corrosion-resistant properties prevent degradation in humid or chemically aggressive environments, while the Schedule 40 wall thickness maintains structural integrity under cyclic pressure loads. The pre-applied sealant eliminates separate taping compounds, reducing installation time and ensuring consistent sealing performance across Class 150 fittings and flanges.
Specification Summary & Compliance
This product features precision NPT threads conforming to ASME B1.20.1 standards with Class 2A thread tolerances for reliable engagement. Manufacturing follows ASTM A733 specifications for seamless stainless steel pipe, ensuring dimensional accuracy and material consistency. The nipple is RoHS 3 (2015/863/EU) compliant and suitable for use with 304 stainless steel fittings and flanges rated Class 150. Dimensions include 1/4" NPT male threads on both ends, 4" length, 0.364" ID, 35/64" OD, and 0.088" wall thickness.
