DN50-DN200 Galvanized Grip Collars for Type B Type C No Hub Coupling

In the ever-evolving world of plumbing and drainage systems, the need for reliable, durable and high-performance components is paramount. At TJTC, we pride ourselves on being at the forefront of innovation in the development of EN877 cast iron pipe fittings and couplings. Our commitment to quality and performance ensures our products not only meet but exceed industry standards, giving you peace of mind knowing your plumbing system will last.

Our grip rings are made from high quality carbon steel with a zinc plated finish for superior corrosion and wear resistance. This ensures they maintain their integrity and performance over time, even in demanding environments. The axial restraint design of our grip rings can withstand tremendous pressure, making them a great addition to any drainage system.

For pipe diameters DN50-100 our clamping rings can withstand pressures up to 10 bar.

For DN150-200, they provide reliable support at 5 bar.

For larger pipes, DN250-300, our clamping rings still offer strong performance at 3 bar.

Grip collars are designed for clamping B-type couplings. Depending on the diameter and coupling type, the coupling can provide an unexpected hydrostatic pressure of 5 bar without restriction, and can provide a maximum of 10 bar with complete restriction. The grip ring can be positioned at a pressure-sensitive point in a sanitary or rainwater system during the first installation, or can be reinstalled at a later stage.
