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.
