Installation Instructions Models 105 & 135 Collar Leak 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. Pipe and coupling joints with a wall thickness greater than 5/32” and less than 5/16” are best repaired with a JCM Collar Leak Clamp utilizing an extra thickness of gasket on one end.
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. Con fi rm the proper size and range of repair clamp. Inspect fi tting to ensure all parts are included. For Models 135 and 105 furnished with stainless steel hardware, see reverse for fastener management. 2. 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. Lubricate the pipe and the fi tting gasket with soapy water . Do not use oil base pipe lubricant. 3. Place clamp place clamp on joint with the extra thick portion of the gasket on the smaller diameter portion of the joint. Tuck tapered gasket in place; mesh fi nger lugs and rotate clamp in direction of arrow on the clamp to smooth tapered gasket fl ap. Before tightening - PUSH CLAMP COMPLETELY UP AGAINST JOINT STEP to assure proper positioning. Position bolting lug for easy access to continued bolt tightening. Engage bolts in receiver lugs and fi nger tighten to hold in place. Ensure tapered gasket is fl at under the clamp. Begin bolt tightening sequence. 4. Tighten all bolts evenly to the following torque values, ensure torque values with calibrated fi eld torque wrench: • 5/8” Bolts to 40 - 50 Foot Pounds of Torque + • 3/4” Bolts to 90 Foot Pounds of Torque+ 5. Complete installation of fi tting, return after approximately 15 minutes and con fi rm minimum bolt torque levels have been maintained.
+During bolt tightening sequence, the installer should take care to prevent overtightening bolts causing the pipe to deform or misshapen.
*Ensure fi tting is suitable for application (con fi rm size, materials, pressure ratings, line content, meets local governing & association standards, etc.). Pipeline operation forces, including pressure fl uctuations, thermal expansion/contraction, movement/shifting, etc. will in fl uence 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 fi tting. 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.
