SAE 45º Flared Fittings

These economical fittings resist mechanical pullout. Flare fittings are easy to disassemble and may be reassembled repeatedly, while maintaining a leakproof connection. They interchange with other manufacturers' fittings.

SAE 45º Flared Fitting
Applications:
Use with copper, brass, aluminum and welded steel hydraulic tubing that can be flared. Manufactured especially for hard-to-hold liquids and gases. These fittings are commonly used on automotive and truck applications.

Assembly Instructions
1. Cut tubing squarely and clean tube end thoroughly to remove burrs.
2. Place nut onto tube. Place threaded end of nut toward end of tube.
3. Flare tube end with flaring tool to provide 45º flare.
4. Clamp tube flare between nut and nose of fitting body by screwing nut on finger tight . Tighten with a wrench an additional 1/4 turn for a metal-to-metal seal.
