Installation Instructions Model 151 All Stainless Steel Gas Repair Clamp Model 153 All Stainless Steel Gas Service Clamp
Read instructions before starting installation* Review of “Tricks of the Trade” on the reverse will assist with installation. DO NOT USE FOR PLASTIC GAS PIPE DO NOT USE FOR THE REPAIR OF POLYETHYLENE GAS PIPE. Suitable for reshaping and marking squeeze off locations. 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. 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 oval necked bolts from lug ears and open the clamp. 3. 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. 4. Tighten all bolts evenly to the following torque values, ensure torque values with calibrated field torque wrench: Nominal Sizes 3” and smaller - 50 Foot Pounds Nominal sizes 4” and larger - 80 Foot Pounds 5. Complete installation of fitting, return after approximately 15 minutes and confirm minimum bolt torque levels have been maintained.

*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. For application review or questions contact JCM Industries at 1-800-527-8482, 903-832-2581
