FEMALE TUBE ADAPTOR - NPT

FEMALE TUBE ADAPTOR - NPT

The Female Tube Adaptor – NPT is designed to connect tube fittings to male NPT (National Pipe Tapered) threaded ports, ensuring a strong, leak-tight joint. One end connects securely to METALOK INDUSTRIES® -style compression tube fittings, while the other features a female NPT thread for integration with tapered male-threaded components. This adaptor is ideal for a wide range of fluid and gas applications, offering both structural reliability and sealing integrity. It is available in sizes from 1/8” to 2” (imperial) and 3mm to 50mm (metric), and is manufactured from corrosion-resistant materials such as Stainless Steel (SS), Brass, Duplex, Monel, and Hastelloy, ensuring durability in harsh environments.

  • Female NPT threaded end for connection to male NPT fittings.
  • Tube fitting end compatible with METALOK and standard compression systems.
  • Available in corrosion-resistant materials: SS, Brass, Duplex, Monel, Hastelloy.
  • Designed for high-pressure, leak-tight performance.
  • Precision-machined for reliable, repeatable connections.
  • Provides a secure, leak-proof transition from tube to threaded piping.
  • Ensures durability and corrosion resistance in tough operating conditions.
  • Reduces installation time with standardized connection points.
  • Enhances system integrity in high-pressure and vibration environments.
  • Suitable for use in oil & gas, chemical, water treatment, and industrial systems.
