Installation Instructions Model 143 Bell Joint Leak Clamp Sizes 14" and Larger Ductile Iron, Cast Iron, C905 PVC
Read instructions before starting 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.
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.
3 . Layout the two halves (bell side, spigot side) of the fitting. The spigot half of the fitting has a raised welded gasket ring on the flange face. This half will be installed on the spigot side of the joint. The gasket ring will trap and compress the gasket into the bell cavity. 4. Install the gasket (Bevel Cut) on the spigot side of the joint with the flat side facing
toward the pipe bell. For large or oversized cast iron pipe an additional gasket has been included to accommodate the pipe diameter. Gaskets may be cut to meet up. Follow original bevel angle to ensure complete match. Slide the gasket toward the joint so that flat side of the gasket meets up with the face of the bell.
Install the fabricated clamp ring segments on the spigot side of the joint. Engage the side clamping bolts loosely to allow rotation of the fitting on the pipe. Ensure that the fabricated clamp ring joint is rotated 90 o (1/4 turn) from the gasket joint. 5. On the bell side of the joint install the second set of clamp ring segments in the same manner. Loosely bolt the segments together to
allow movement. Complete installation by inserting the long rods through the segments and over the joint into the corresponding bolt holes of the opposite clamp rings. Loosely assemble nuts on the ends of the bolts.

6. Take up excess slack from side clamping bolts, but allow enough play to let the fitting move slightly on the pipe when tightening rods to compress the gasket. Hand tighten the rod nuts and ensure the spigot ring is centered on the pipe and is making full contact with the face of the gasket. Tighten the rod nuts evenly until the spigot gasket compresses against the joint and the leak stops. Tighten nuts to approximately 60 - 70 Ft-lbs. of torque. Install the second set of nuts on rods and tighten to 60 - 70 Ft-lbs. Complete installation by tightening side clamping bolts to approximately 80 - 100 ft. lbs of torque. To ensure integrity of installation, wait 15 minutes, inspect for leaking, and confirm bolt torque. If necessary, loosen clamping bolts, re- tighten rod bolts evenly as required to stop the leak. Re-tighten clamping bolts. from Ring Joint

*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
