S-4475K272 3.826" ID x 4 1/2" OD x 3 1/2" Long ASME B1.20.1, ASTM A733 Thick-Wall Stainless Steel Threaded Pipe Nipples and Pipe

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316/316L stainless steel construction for long-lasting performance in harsh chemical and marine environments.
• Exceptional pressure handling due to Schedule 80 thick-wall design (0.337" wall thickness), ensuring reliability in high-pressure air, hydraulic, and steam systems.
• Leak-resistant connections provided by NPT threads on both ends, conforming to ASME B1.20.1 for secure, standardized fittings.
• Enhanced durability and purity from seamless construction, minimizing weak points and contamination risks in fluid and gas transfer.
• Broad media compatibility for safe use with air, hydraulic fluid, natural gas, oil, steam, and water, thanks to 316/316L material integrity.
• Regulatory compliance assurance with RoHS 3 standards, making it suitable for environmentally regulated and sensitive industrial applications.
• Precision manufacturing per ASTM A733, guaranteeing consistent dimensions (4" pipe size, 3 1/2" length) and reliable integration into Class 3000/600 flange systems.

Professional Applications & Engineering Value

This 4" Schedule 80 stainless steel threaded pipe nipple is engineered to address critical challenges in high-pressure industrial systems. Constructed from seamless 316/316L stainless steel, it resists pitting and corrosion from aggressive media like hydraulic fluid, steam, and natural gas, reducing maintenance downtime. The NPT threading on both ends ensures a tight seal, preventing leaks in demanding applications such as oil pipelines or water treatment plants. Its thick-wall design (Schedule 80) withstands intense pressure cycles, while compliance with ASME B1.20.1 and ASTM A733 ensures dimensional accuracy and material reliability. Ideal for pipe connections in Class 300/600 flanges, this nipple delivers long-term value by minimizing failure risks in critical infrastructure.
