The 3/16 in. x 1/8 in. Brass OD Tube x Male NPT Flareless Branch Tee is a brass flareless compression-type branch tee 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.

Key Features
- No tube flaring required — cut tube square and assemble
- Ferrule or cutting ring creates metal-to-metal seal rated for high-pressure service
- 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.
