GAS PRODUCT INSTALLATION MANUAL Style 130 Repair Clamp

  1. DO NOT CUT GASKET --IT IS CORRECT LENGTH AND WIDTH.

  2. Clean pipe thoroughly where gasket is to seat. Smooth any rough spots.

  3. Lubricate pipe with soap-water to help gasket slide into correct position.

  4. Open the clamp and place it around the pipe, making sure the spanner at split of clamp is located under the band. Do remove the bolts, since bolt heads drop into the slots in lungs without being removed.

  5. Hook bolts into slots and finger-tighten. Gasket ends should butt together-- NOT overlap.

  6. Locate the joint in the gasket away from holes being repaired.

  7. Center the clamp over the leak and tighten the bolts to 50 ft. lbs. torque.

Sample Note: When pipe movement out of the clamp might occur, proper anchorage of the pipe must be provided.

  1. Clean pipe thoroughly where gasket is to seat.

  2. Lubricate gasket and clean area of pipe with soap-water (ethylene glycol should be added in freezing weather).

  3. Place clamp around pipe with gasket centered over leak. Hook bolt head in slotted lug and tighten the nut.
