Metal Braid

To minimize braid flare, wrap the area of the hose to be cut with masking tape. Cut the hose with a suitable cut off wheel or fine toothed hack saw blade and then remove the tape.

Non-Metallic Braid

Wrap with Scotch Magic Tape 810 on area to be cut. Cut the hose with a sharp knife then carefully remove the tape.

Braid tends to flare more at one end than the other. Assemble both sockets back to back from the less flared end.

Screw the olive onto the hose until the hose protrudes through. Don’t cross thread or force the olive. Make sure the braid goes over the olive.

Pull the sockets up over the olives. Lubricate the fitting thread with a light oil. Insert the tail into the hose. Engage the fitting and socket threads. Screw together as far as possible by hand.

Lightly grip the socket in a set of vice jaws and fully tighten the fitting.

Metallic Braid

Socket should be no more than 1mm away from the fitting face.

Non-Metallic Band

Socket should be touching the fitting face

Final Step

Clean the assembly fittings and proof pressure test the assembly to 1-1/2 times the system working pressure.

Note

NEVER loosen fittings once assembled to achieve the desired orientation. ALWAYS use new olive when reusing an end fitting.

IF IN DOUBT contact BMRS.

Step One

Having established the required length, cut the hose with a suitable cut off wheel or fine toothed hack saw blade. To minimize braid flair, wrap the area of the hose to be cut with masking tape.

Step Two

Remove the masking tape and trim any loose braid wires. Remove burrs from inside diameter of the PTFE tube with a sharp knife. Clean the hose to ensure all loose particles and dirt are removed from the bore.

Step Three

Braid tends to flair at one end more than the other, identify the end that has flared less and assemble two sockets back to back from this end.

Step Four

Separate the braid from the innercore at each end using the appropriate tool. If the tool is not available, the braid may be loosened by working the hose over the fitting tail.

Step Five

Push the olive over the end of the tube ensuring it goes under the braid wire.

Step Six

Lubricate the fitting and socket threads. Hold the fitting hexagon in a set of vice jaws, push the hose over the tail using a twisting action until the olive is seated against the chamfer on the thread shoulder. Push the socket forward and engage its thread on the fitting thread.

Step Seven

Using the appropriate size spanner tighten the two halves of the fitting together until there is a maximum gap of 0.75mm (0.031 inches) between the fitting hex and the socket.

Step Eight

Clean the assembly and proof pressure test it to twice the system operating pressure.

Final Step

Clean the assembly fittings and proof pressure test the assembly to 1-1/2 times the system working pressure.

Note

NEVER loosen fittings once assembled to achieve the desired orientation. ALWAYS use new olive when reusing an end fitting.

IF IN DOUBT contact BMRS.

Aluminium Flared Fittings

1. Cut the aluminium tube square and deburr the inside and outside diameters (not excessively).

2. Assemble fitting by sliding the sleeve and nut over the tubing.

3. Flare the tube with the appropriate proprietory flaring tool. After flaring, the tube end should conform to the figure and table below.

Precision CNC Tube Measuring and Bending

The following information catalogs the current bend tools that are available. This list is constantly being added to, so check with us if your specific requirement does not appear to be listed.

The “Clamp Length” is the minimum distance between bends that can be achieved (See illustration below). This figure, plus a small clearance allowance of 1/8″, should be taken into account when designing complex compound tube bends. In any specific compound tube bend design only one Center Line Bend Radius should be selected.

Bend Angle is defined as the actual angle the tube is bent through.

Brown & Miller Racing Solutions is able to interpolate all common CAD and 3D model data directly into our bending equipment. We can also work with X, Y, Z co-ordinates, mock up parts or existing patterns.
