S-2729K52 0.364" ID x 35/64" OD x 4" Long ASTM B687 Standard-Wall Brass Threaded Pipe Nipples and Pipe with Sealant

Key Features & Benefits at a Glance

• Instant leak-proof installation with factory-applied acrylic thread sealant, eliminating separate sealing steps and reducing assembly time
• Superior corrosion resistance from 230 brass construction, ensuring long-term reliability in demanding environments
• Seamless design integrity for enhanced pressure containment and reduced failure risks in air, gas, oil, and water systems
• Precision NPT threading on both ends for secure, standardized connections with Class 125 brass fittings and Class 150 flanges
• Robust Schedule 40 compliance providing optimal wall thickness (0.088") for industrial pressure and mechanical stress resistance
• Multi-medium compatibility engineered to handle air, natural gas, oil, and water applications without degradation
• Regulatory confidence with full ASTM B687 material standards and RoHS 3 compliance for global industrial use

Professional Applications & Engineering Value

This 1/4" NPT brass pipe nipple delivers critical sealing reliability where fluid or gas containment is paramount. The seamless 230 brass construction prevents weak points common in welded alternatives, while the integrated acrylic thread sealant actively fills micro-gaps during threading—effectively solving leakage issues in compressed air lines, fuel transfer systems, and industrial plumbing. Its NPT thread type and Schedule 40 dimensions ensure drop-in compatibility with standard brass fittings, reducing installation errors in high-vibration environments. Engineers specify this nipple for its ability to maintain seal integrity under thermal cycling and moderate pressure surges, making it ideal for natural gas connectors, hydraulic instrument lines, and process water manifolds.

Specification Summary & Compliance

Manufactured to ASTM B687 standards for copper-brass seamless pipe, this nipple maintains precise NPT thread form with Class 2A tolerance for consistent engagement. Dimensional adherence includes 4" length, 0.364" ID, and 35/64" OD with 0.088" wall thickness per Schedule 40 requirements. The product is fully RoHS 3 (2015/863/EU) compliant and suitable for systems requiring 125 Class brass fittings and 150 Class brass flanges.
