Description

The JCM 153 all stainless steel gas service clamp meets USDOT Code 192 and gives an immediate repair, temporary or permanent, of breaks, cracks, splits, corroded areas, pin holes and similar damage on gas lines. The full-circumference gasket seals the whole pipe, and the stainless band conforms to flat and uneven pipe exteriors.

A threaded service outlet in the band makes a gas service connection in the same fitting, 3/4 to 2 in, IP (NPT) or CC thread.

Cast stainless steel lugs (CF8, equal to 304) and a band TIG-welded to the lugs for its full length, then passivated, suit acidic, hot or aggressive environments.

Typical application: Repair, temporary or permanent: breaks, cracks, splits, holes, corroded areas and pin holes; connection of plain-end pipe.

Key Features

  • Meets USDOT Code 192
  • 1/4 in thick gridded gasket on 3 in and larger fills pits and voids
  • Molded-in stainless bridge plate prevents pinched gasket
  • Drop-in, swing-away bolts with no loose parts; bolts replace individually
  • Suitable for reshaping and marking squeeze-off locations
What Ships and What It Needs to Run

Included: the tapped clamp with its full-circumference gasket and molded-in stainless bridge plate, cast stainless lugs and drop-in track bolts with nuts and washers.

Service fitting, ordered separately. The service valve or fitting threads into the outlet: IP is NPT thread, CC is the AWWA corporation thread.

Pipe anchorage, provided at install. The clamp seals but does not restrain the pipe.

Working Pressure

100 PSI gas on 2-8 in; 60 PSI gas on 10-12 in. JCM's installation instructions rate the clamp for gas service at 100 PSI on cast iron and steel pipe through 8 in and 60 PSI on 10 and 12 in. Higher capability depends on the application; send us the pipe, damage and pressure for JCM's rating.

Before You OrderTapped clamps are non-returnable (JCM). Confirm size, outlet and thread before ordering.
For cast iron and steel gas mains; JCM does not use the 120 and 150 gas clamp series on polyethylene gas pipe.
Anchor the pipe: the clamp seals the full circumference but does not hold the pipe against lateral movement, so JCM calls for proper anchorage wherever the pipe could move out of the clamp.
