Assembly Instructions
The assembly ol Brennan Steel and Stainless
Steel Bite-Type Fittings involves four steps:
1) cutting, debut ring and cleaning; 2) pre-
setting the ferrule to the tubing: 3) ferrule bite
inspection; and 4) Installation.
Cutting, Deburring & Cleaning
i. Square-cut the seamless or welded-and-drawn
tubing usr>g a hacksaw with a fine-tooth blade,
or a circular toothed cut-oil saw. Use only
tubing that is fully annealed for bending and
flaring.
2. Remove all burrs and sharp edges on the
tube by lightty deburring the I D. and O D
Emery paper may be used to perform this task
3. Wipe the tube end completely with a c*ean
cloth. Be sure to remove all metal chips Irom
the tube end
Pro-Setting Ferrule to the Tubing
This procedure must be followed to ensure the
proper location of the ferrule to the tubing.
i. Lubricate the fitting body thread and the
thread of the nut.
2. Slip the nut and ferrule over the deburred end
of the tube. The long, straight end of the ferrule
must point toward the deburred tube end.
3. Lubricate the ferrule.
4. Position the deburred tube end squarely on
the shoulder of the fitting body.
5. Manually screw the nut onto the lilting body
until rt is finger-tight.
6. Put a reference mark on the nut and the tube.
7. Hold the tube firmly on the fitting body and
tighten the nut an additional l3/* turns. Proper
assembly of bite-type fittings is dependent up<xi
the ferrule traveling a prescribed distance into
the tilting throat This alows it lo 'bile" into the
tube, creating a strong grip and seal.
8. The use of a Ferulsel tool is recommended tor
sizes -08 through -32".
Ferrule Bite Inspection
The following inspection procedures must be
completed prior to final assembly.
1. Disassemble the fitting.
2. The tube surface must have a raised ridge of
metal that Is at least 50% of the thickness of
the leading edge of the ferrule.
3. There must be a slight bow to the pilot section
of the ferrule.
4. The tail of the ferrule should be snug against
the lube.
5- A slight indentation around the deburred end
of the tube Indicates that the tube was bottomed
in the fitting. If this indentation is not visible,
the ferrule may not be properly seated.
6. Do not rotate the ferrule.
