Installation Instructions Models 111 Full Repair Clamps
Read instructions before starting installation* For purposes other than water, contact JCM Industries for application and product assistance. Review of “Tricks of the Trade” on the reverse will assist with installation.
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. For fittings furnished with stainless steel hardware, see reverse for fastener management. 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 square necked bolts from lug ears and open the clamp. 3. Wrap gasket around pipe and center over damaged area. Install stainless steel clamp shell over the gasket, ensure gasket stainless steel armor plate is centered at the open gap between shell lugs. Placement stainless “tips” aid in feeling positioning in adverse conditions. Engage bolt(s) in slotted receiver lugs and finger tighten to hold in place. Begin bolt tightening.+
4. Tighten bolt(s) evenly to the following torque values, ensure torque values with calibrated field torque wrench: Nominal sizes 1/2” - 1-1/4” with 3/8” Bolts 25 Foot Pounds Nominal sizes 1-1/2” - 2” with 7/16” Bolts 35 Foot Pounds
5. Complete installation of fitting, return after approximately 15 minutes and confirm minimum bolt torque levels have been maintained. Recommended for the following service ratings: Water Service 150 PSI Gas Service 100 PSI
+During bolt tightening sequence, the installer should take care to prevent overtightening bolts causing the pipe to deform or misshapen. *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. INT111-022022 For application review or questions contact JCM Industries at 1-800-527-8482, 903-832-2581
