Professional Applications & Engineering Value

This 304/304L stainless steel threaded pipe nipple is engineered to address common industrial challenges such as fluid leakage, corrosion-induced failures, and installation inefficiencies. The welded construction and NPT thread type create a tight, durable seal that resists loosening under thermal cycling and mechanical stress. With factory-applied PTFE thread sealant, it eliminates the need for on-site sealant application, reducing contamination risks and ensuring consistent performance in air, natural gas, oil, steam, and water systems. Ideal for industrial pipe fittings in chemical plants, HVAC, and oil refineries, it enhances system reliability by preventing leaks in high-pressure and temperature environments, while the stainless steel material maintains integrity against rust and chemical exposure.

Specification Summary & Compliance

This product features NPT threading conforming to ASME B1.20.1 for precise fit and ASTM A733 for material specifications, ensuring dimensional accuracy and strength. It is manufactured with a Schedule 40 wall thickness (0.109") and standard pipe sizes (1/2") for consistent performance. Compliant with RoHS 3 (2015/863/EU), it meets environmental regulations, supporting safe and sustainable industrial applications.
