JCM optimum range couplings employ the mechanical compression joint principle to join 2-pieces of plain end pipe. This stress relieving flexible joint eliminates precise cutting and fitting in the field while providing for deflection, expansion-contraction, pipe settlement and a quick easy means of disassembling the system for maintenance.

• More versatility accommodates larger pipe ranges
• More performance higher working pressures
• JCM optimum range ductile iron couplings offers a new gasket concept that delivers superior performance
• Larger range capabilities for fitting oversized, exotic and coated pipe diameters
• Internal ribbed design increases sealing capability and grip on both low and high ranges of nominal pipe sizes
• JCM's unique design for stress relief built into the gasket - eliminates gasket pinch in applications requiring offset, deflected and pipe settlement
• Sleeve, flanges and middle ring - ductile iron
• Gaskets - nitrile butadiene rubber (NBR, Buna-N) specially compounded new rubber polymer for superior shelf life and resistance to permanent set, gasket temperature range -40 to 212 deg F, gasket suitable for use on water, salt solutions, mild acids, bases and sewage
• Bolts - 5/8 in corrosion-resistant, high strength low alloy oval neck track head bolts per ASTM A242/ANSI 21.11/AWWA C111 and heavy hex nuts per A563 or equal
• 242 long length middle ring allows for deeper pipe insertion and accommodates wide gaps between pipe ends
• Reduces inventory
• Non-compromising design

Standards/Certifications: ANSI/AWWA C219, ANSI/NSF 61 annexure G and 372 certified

Applications: For SDR35, IPS PVC, C-900 PVC, ductile iron, steel, cast iron and A/C pipe classes 100, 150 and 200
