No-hub couplings are engineered to connect No-hub cast iron pipe and fittings, cast iron pipe and plastic pipes or bronze pipes. The couplings consist of a high quality elastomeric compound gasket housed inside a stainless steel corrugated shield.
1. Available in size range from 1 1/2″ - 12″ (DN40 50 70 75 100 125 150 200 250 300)
2. Different various materials can be chosen by customers:
Shield: 300/301/304/316 stainless steel
Band: 300/301/304/316 stainless steel
Screw housing: 300/301/304
Screw: 301/304 stainless steel/carbon steel
Eyelets: 300/301/304/316 stainless steel and flexible
Gasket: Neoprene elastomer/NBR/EPDM
The Grip collars are fixed outside of the shielded couplings. They can strengthen the pressure which pipes bear.
The dimensions can be from DN50-DN300.
The bear pressure is DN50-DN100 10bar, DN150-DN200 5bar, DN250-DN300 3bar.
