Description
The JCM 113 multi-band heavy duty patch clamp is a fast, permanent repair for pin holes, punctures and splits in steel and other pipe where there is no beam break. Multi-band construction carries the repair to 36 in pipe.
For complete breaks, use the JCM 101 or 102 universal clamp couplings.
Typical application: Repair, temporary or permanent: pinholes, corroded areas, holes, longitudinal splits and cracks.
Key Features
- Permanent repair of pin holes, punctures and splits
- Gridded gasket compounded for water, salt solutions, mild acids and bases; Buna-N optional
- Ductile iron lugs with 304 or 316 stainless options
- Low-alloy steel bolts; 304 or 316 stainless optional
- 6 and 12 in widths; larger and custom sizes built to order
What Ships and What It Needs to Run
Included: the clamp with its gridded gasket, ductile iron lugs and low-alloy steel bolts and nuts.
Pipe anchorage, provided at install. The clamp seals the damage but does not restrain the pipe.
Genuine JCM Industries equipment, factory-new in original packaging — sold and supported by Watermain Supply, an independent industrial supplier.
12-Month Warranty
Covered for 12 months from the date of purchase against defects in materials and workmanship. Keep the dated invoice as proof of purchase.
Working Pressure
Rated by application. JCM rates the pressure capability of this clamp for each installation: it depends on pipe size and type, the type and extent of the damage or joint condition, line content, temperature and installation. Send us the pipe OD and type and the working and test pressures, and we will obtain JCM's rating and a submittal for your application.

Before You OrderFor complete breaks or beam breaks, choose a JCM 101 or 102 universal clamp coupling instead.
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.
For a submittal or an odd OD, email sales@watermainsupply.com with the pipe OD, pipe type and line content.
