JCM 251 Heavy Duty Custom Built Steel Coupllings Now offering JCM 251 Heavy Duty Steel Bolted Couplings for joining two plain end pieces of pipe of the same outside diameter without welding or exact field cutting of pipe ends. A combination of the substantial middle ring and two heavy follower flanges join together with the proper number of bolts to fully compress the gasket into the middle ring, creating the flexible, yet leak-proof seal.
JCM 251 Heavy Duty Steel Bolted Couplings offer advantages in a piping system:
No beveling, costly threading, exact pipe alignment or fitting is required Make assembly/disassembly of pipe sections fast. Quick, simple to install, using only a wrench. Gaskets absorb vibration and pipe movement Permits limited expansion/contraction Curves can be laid with straight pieces of pipe Simple, rugged and serviceable, Available for Steel, PVC, HDPE or Ductile Iron (cast iron) pipe sizes Available with restraint systems Available in American Iron and Steel (AIS/BABA) Meets AWWA Standard C219 Bolted Sleeve-Type Couplings for Plain-End Pipe
JCM 251 Heavy Duty follower ring material provides the strength and power to fully compress the gasket into the middle ring - without flexing, stretching or bending. The robust material provides consistent pressure across the full face of the gasket, preventing gasket shifting or protrusion.
The JCM 251 Heavy Duty Steel Coupling delivers the strength, durablity and reliability end users have come to appreciate in JCM fittings.
JCM 251 Heavy Duty Couplings are available in sizes larger than 16” and are customizable for undersized/oversized and unique pipe diameters. The adapability these couplings lend make possible flanged adapters, dismantling joints, reducing and transition couplings, pipe end caps and many other fittings.
