Professional Applications & Engineering Value

This 316/316L stainless steel threaded pipe nipple with integrated PTFE thread sealant addresses critical leakage concerns in industrial fluid and gas handling systems. The seamless construction eliminates potential weak points while the NPT threading ensures precise engagement with mating components. Engineered specifically for demanding applications including steam lines, oil transfer systems, and natural gas distribution, this nipple provides reliable performance where thermal cycling and chemical exposure would compromise inferior fittings. The combination of corrosion-resistant material and factory-applied sealant creates a maintenance-free solution that reduces downtime and prevents costly system failures in chemical processing, power generation, and industrial manufacturing environments.

Specification Summary & Compliance

Manufactured to exacting dimensional standards with NPT threads conforming to ASME B1.20.1 specifications, this pipe nipple maintains precise Class 2A thread tolerances for optimal sealing performance. The Schedule 40 wall thickness (0.088") provides robust pressure containment while the seamless construction meets ASTM A733 requirements for welded and seamless carbon and alloy steel pipe nipples. Compliance with RoHS 3 (2015/863/EU) ensures environmental responsibility, making this fitting suitable for regulated industries requiring strict material composition controls.
