The 3/8 in. x 3/8 in. Brass Poly-Flo x Male NPT Adapter is a brass Poly-Flo adapter that creates a leak-tight tube connection without flaring the tube end. A ferrule or cutting ring bites into the tube OD as the nut is tightened — forming a metal-to-metal seal rated for high pressure without any tube preparation beyond a clean, square cut. Flareless fittings are the standard in hydraulic instrumentation lines, high-pressure control systems, and OEM equipment where tube flaring is impractical.

  • Brass construction compatible with copper, brass, and compatible aluminum tubing
  • Resists vibration loosening better than soft-ferrule compression fittings on rigid tubing
  • Standard in hydraulic instrumentation, fuel systems, and OEM control equipment

Common Applications

Hydraulic instrumentation and gauge lines, fuel injection system tubing, high-pressure instrument air, OEM control panel plumbing, and any high-pressure tubing connection on rigid steel or copper tube where flaring tools are not available.
