Hose Assembly Length and Orientation Measurement

When ordering factory made assemblies it is important to specify the length and fitting orientation in a consistent manner. The convention used by BMRS is that recognized internationally as the standard method.

 
 
Assembly Length
The diagrams below Illustrate how to measure the overall length of the assembly with various styles and configurations of end fittings attached. Assembly lengths given to BMRS without further definition will be produced to this convention.
 
 
 
Elbow Orientation

Where an assembly has an elbow or banjo fitting at both ends or a combination of elbows and banjos, the angular orientation between the fittings must be slated. This is measured in degrees anti-clockwise.

The angle is measured from the center line of the nearest fitting when this fitting is positioned at 6 o'clock to the center line of the other fitting.

Note: In this example the orientation is 180°.

Metal Braid:   Non-Metallic Braid:    
To minimize braid flare, wrap the area of the hose to be cut with masking tape. Cut the hose with a suitable fine toothed hack saw blade and then remove the tape.   Wrap PTFE (teflon) thread tape on area to be cut. DO NOT use adhesive tape of any type. 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. Make sure the braid goes over the olive.   Trim the hose back to be flush or a maximum of 1 mm proud of the olive.   Ensure the hose is cut cleanly and square.
   
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 Braid:
Socket should be touching the fitting face.
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.
  Clean the assembly fittings and proof pressure test the assembly to 1-1/2 times the system working pressure.
