Review of “Tricks of the Trade” on the reverse will assist with installation.
For purposes other than water, contact JCM Industries for application and product assistance.
1.
Clean and scrape pipe. Remove any scale, pipe wrap, debris or dirt that may interfere with the
complete sealing of the gasket. Inspect pipe for integrity, size, outside diameter and surface
irregularities. Confirm the proper size and range of repair clamp. Inspect fitting to ensure all
parts are included.
2.
Lubricate the pipe and the fitting gasket with soapy water.
Do not use oil base pipe
lubricant.
Loosen nuts of bolts and back nuts to the end of the bolt (complete removal of bolts
is not necessary). Release oval necked bolts from lug ears and open the clamp.

.
For Models 101, 103 -
Place clamp on pipe and center over damaged area. Tuck tapered
gasket in place; mesh finger lugs and rotate clamp in direction of arrow to smooth tapered
gasket flap. Position bolting lug for easy access to continued bolt tightening. Engage bolts in
receiver lugs and finger tighten to hold in place. Begin bolt tightening
sequence. See step 4.
For 102, 104 Multi Band Clamps - with multi lug segments. One section has “closed ears” (A)
and “open ears” (B) for bolt engagement. Locate lug segment with open “ear” to loosen bolts.
Loosen bolts of other lug segments. Do not remove bolts.
Open clamp at open ear lug segment and place clamp on pipe so that
gasket flap is on top is facing you. Bring back half of clamp around pipe.
Feed tapered gasket end into place, mesh top lug fingers into “open ears”
and engage bolts. Rotate clamp in direction of arrow to smooth tapered
gasket flaps. Finger tighten bolts to hold in place. Begin tightening bolts to
proper torque values. Continue around pipe at each lug segment. Avoid
tightening lugs to metal bound at any one segment -
gaps between lugs
should be approximately even on both sides. Continue bolting sequence to proper torque values
below.
4.
Tighten all bolts evenly to the following torque values, ensure torque values with calibrated field
torque wrench:
5/8” Bolts to 70 Foot Pounds
3/4” Bolts to 90 Foot Pounds
5.
Complete installation of fitting, return after approximately 15 minutes and confirm minimum
bolt torque levels have been maintained.
For JCM 103 and 104 Tapped Clamps, proceed with tapping process.
*Ensure fitting is suitable for application (confirm size, materials, pressure ratings, line content, meets local governing & association standards, etc.).
Pipeline operation forces, including pressure fluctuations, thermal expansion/contraction, movement/shifting, etc. will influence the success of the
application. Proper anchorage, restraint, harnessing, thrust blocks or other devices must be provided to prevent pipe movement (lateral, angular, axial) or
pipe pullout from the bolt-on fitting. Inspection of the pipe integrity is the responsibility of the end user. JCM recommends the use of calibrated torque
wrench. Failure to follow installation instructions will result in voided product warranty.
