G’day,
I did some more research into the re-usabilty of 45° flared fittings and
found that the Parker Hannifin Corporation states:
45 FLARE FITTINGS
Advantages
This economical fitting resists mechanical pullout. Can be assembled and
disassembled repeatedly. Manufactured from CA 360, CA 345 or CA 377 brass.
Specifications
Listed with Underwriter’s Laboratories for flammable liquid, marine,
refrigeration and gas applications. Meets functional requirements of SAE
J512 and J513, ASA and MS (Military Standards). Refer to list of UL listed
fittings on page 8 for specific configurations.
Applications
Use with copper, brass, aluminum and welded steel hydraulic tubing that can
be flared. Manufactured especially for hard-to-hold liquids and gases.
Working Pressure Ranges
Temperature and type of tubing used are important factors. However, the
following table is a good guide for proper selection. Temperature 73°F with
copper tubing:\
PSI TUBE TUBE
O.D. (IN.) WALL (IN.)
2800 1/8 .030
1900 3/16 .030
1400 1/4 .030
1200 5/16 .032
1000 3/8 .032
750 1/2 .032
650 5/8 .035
550 3/4 .035
450 7/8 .035
Temperature Ranges
From -65° to +250°F.
Vibration
Short nut may be used when vibration is minimal. The long nut offers
additional vibration capacity.
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 45° 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.
Flare fittings are easy to disassemble and may be reassembled repeatedly,
for a leak-proof connection.
