S-1455N148 0.493" ID x 43/64" OD x 3" Long ASME B1.20.1, ASTM A733 Standard-Wall Stainless Steel Threaded Pipe Nipples and Pipe with Sealant

Key Features & Benefits at a Glance

• Leak-proof performance with factory-applied PTFE thread sealant, eliminating the need for additional sealants and preventing fluid/gas escape in pressurized systems.
• Superior corrosion resistance from 304/304L stainless steel construction, ensuring long-term reliability in harsh environments exposed to moisture, chemicals, and extreme temperatures.
• High-pressure compatibility with Schedule 40 wall thickness and Class 150 rating, providing robust performance for air, natural gas, oil, steam, and water applications.
• Precision threading with NPT (National Pipe Taper) on both ends for secure, tight-fitting connections that resist vibration loosening.
• Seamless durability with one-piece construction, reducing failure risks from welds and enhancing structural integrity under stress.
• Time-saving installation due to pre-applied sealant and standardized 3-inch length, minimizing assembly errors and labor costs.
• Regulatory compliance with RoHS 3, making it suitable for regulated industries requiring environmentally safe components.

Professional Applications & Engineering Value

This 3/8 NPT Schedule 40 stainless steel threaded pipe nipple is engineered to address critical challenges in industrial fluid and gas systems. The seamless 304/304L stainless steel body resists pitting and cracking, while the integrated PTFE thread sealant ensures immediate, reliable sealing without separate tape or compound—reducing installation time and leak points. Ideal for air, natural gas, oil, steam, and water applications, it maintains integrity in high-temperature and corrosive environments, such as chemical processing, HVAC, and oil/gas pipelines. The male threaded ends and tapered NPT threading facilitate secure connections in tight spaces, preventing disassembly under vibration. By combining material resilience with pre-applied sealing, this nipple minimizes downtime and maintenance, delivering consistent performance in demanding settings like plant utilities and compressed air systems.

Specification Summary & Compliance

This product adheres to ASME B1.20.1 for NPT thread dimensions and ASTM A733 for seamless stainless steel tubing, ensuring precise Class 2A thread tolerances and dimensional accuracy (3-inch length, 0.493" ID, 43/64" OD). It is RoHS 3 (2015/863/EU) Compliant, meeting environmental regulations for hazardous substance restrictions. The Schedule 40 wall thickness (0.091") and Class 150 rating guarantee pressure suitability, while the 304/304L stainless steel material aligns with industry standards for corrosion resistance and mechanical strength.
