What is Stainless Steel Flex Exhaust Tubing?

FLEXIBLE TUBING’S FUNCTION IS TO PREVENT EXCESSIVE STRESS ON EXHAUST SYSTEM COMPONENTS  BY ABSORBING VIBRATION AND THERMAL EXPANSION THAT WOULD OTHERWISE CAUSE SYSTEM COMPONENTS TO SHAKE LOOSE AND BREAK. CUTTING AND INSTALLATION INSTRUCTIONS FOR FLEXIBLE TUBING

Can I Cut Flex Exhaust Tubing?

FLEXIBLE TUBING CAN TWIST OR UNRAVEL WHEN CUT, CAUSING ITS DIAMETER TO CHANGE AND MAKING INSTALLATION DIFFICULT. THIS OCCURS BECAUSE FLEXIBLE TUBING MUST MAINTAIN FLEXIBILITY IN ORDER TO FUNCTION PROPERLY, AND, THEREFORE, CANNOT BE TIGHTLY WOUND IN THE MANUFACTURING PROCESS. HOWEVER, FLEXIBLE TUBING CAN BE MANAGED FOR TROUBLE-FREE INSTALLATION BY FOLLOWING THESE GUIDELINES.

CUTTING

1. PREPARE:

PLACE A TACK WELD BETWEEN CONVOLUTIONS ON EACH SIDE OF THE INTENDED CUT TO KEEP ENDS FROM TWISTING OR UNRAVELING. IF A WELDER IS NOT AVAILABLE, INSERT A MANDREL OR BACK-UP PIPE INTO THE TUBING AND PLACE A PUNCH MARK DIRECTLY ON CONVOLUTIONS ON EACH SIDE OF THE INTENDED CUT.

2. CUT:

PLACE THE TUBING SECURELY IN A VICE. CUT WITH A METAL CUTTING BAND SAW OR A HACKSAW WITH 32 TEETH PER INCH.

3. TRIM:

EACH SIDE OF THE CUT WILL NOW HAVE A SPIRAL “TAIL” THAT MUST BE REMOVED TO THE POINT AT WHICH IT IS ATTACHED. BEND EACH TAIL UNTIL IT BREAKS, OR BEND AND USE CUTTING SHEARS TO REMOVE.

4. DEBURR

DEBURR BOTH CUT SURFACES WITH A HAND- OPERATED DRUM SANDER OR FILE.  

How do I Prepare Flexible Exhaust Tubing for Installation?

TO PROVIDE ADEQUATE FLEXIBILITY, FLEX TUBING SHOULD BE INSTALLED IN A HALF EXTENDED STATE. 1. TO REACH HALF EXTENSION, PLACE THE MIDDLE OF THE TUBING OVER THE EDGE OF A WORK BENCH OR TABLE,  PUSH DOWN ON BOTH HALVES AND BEND AS MUCH AS POSSIBLE. 2. PLACE THE ENTIRE PIECE OF TUBING ON A TABLE AND PUSH THE END DOWN UNTIL STRAIGHT- ENDED. THE TUBING IS NOW AT HALF EXTENSION.

NOTE: DO NOT USE FLEXIBLE TUBING TO FORM AN EXHAUST PIPE BEND. USE ELBOWS INSTEAD
