Caravan Flex Joint Assembly Instructions
1. Slip the metal retainer on the system piping with the larger
diameter side facing the end of the pipe to be joined. The
3" flex joint has a single piece serrated metal retaining
ring. This retaining ring should be seated in the recess in
the inner diameter of the gasket with its mounting tabs
overlapping slightly where the ring splits. The 1-1/2" flex
joint has a 2 piece serrated retaining ring that must be
installed in the inner recess of the gasket with its ends
butting.
Work the gasket with the serrated metal retaining ring onto the pipe. When installing the gasket be sure the retaining rings seat
properly around the pipe. On the 1-1/2" flex joint install the bottom half of the gasket first leaving the other half of the retaining ring
free at the top. Then stretch the top of the gasket with the ring over the top of the pipe. When installing the gaskets if a lubricant
is needed, use a soap and water solution only. DO NOT use any oil based lubricants.
2. The gasket must be fully seated in the metal retainer (press together with pliers if necessary). BE SURE THE GASKET IS
SEATED ON AN UNTHREADED SECTION OF PIPE AT LEAST 1" FROM THE END. Slip the flared end of the Slant/Fin
header tube over the pipe and seat against the gasket. Follow illustration a or b for cast end cap or piping.
a) b)
3. Open hinged metal clamp and slip over joint. Be sure that the flared end of the steel tubing, the retainer ring and the gasket
are enclosed within the clamp.
4. Install the bolt and lock nut and tighten the lock nut to
the following torque values: 1-1/2" flex joint is 140-160
inch-pounds, 3" flex joint is 220-240 inch-pounds.
NOTE: On 3” schedule 40 pipe, spacing between clamps is
approximately 3/8” when properly torqued.
On 1-1/2" schedule 40 pipe, spacing between clamps
is approximately 1/4" when properly torqued.
