Flare Fittings
SAE 45°/ JIC 37° Flare Fittings
ATFIT Flare Fittings are an economical and reliable choice for a metal-to-metal seal that resists mechanical pull-out. Our fittings meet the stringent requirements of SAE J512 and SAE J513 standards.
1. Assembly
- Cut the tubing squarely and clean the end thoroughly to remove burrs.
- Place the nut onto the tube with the threaded end facing the tube end.
- Use a flaring tool to create a 45° flare at the tube end.
- Clamp the flared tube end between the nut and the fitting body. Tighten the nut finger-tight, then secure it with a wrench for an additional 1/4 to 1/2 turn to ensure a leak-proof metal-to-metal seal.
- Flare fittings are easy to disassemble and can be reassembled repeatedly, maintaining a leak-proof connection.
2. Material Specification
- Free cutting IS-319/CZ-121
- CA360 Brass for bar stock fittings
