Rubber Shaft Coupling Joint

Our Rubber Shaft Coupling Joint is made for big size pipes over DN300. We use it in water supply, city pipes, pump stations, And the water circulates systems. We have been making pipe parts for over 20 years. This rubber shaft coupling joint has high strength, pull-out prevention, and better safety. It keeps big size pipes running safely. We use high-toughness NBR rubber for the sphere. We use a three-layer design with high-temperature high-pressure vulcanization. The flanges are hot-dip galvanized carbon steel with steel limit rods.

This thing works from -20℃ to 120℃. It handles pressures from PN6 to PN16. Each rubber shaft coupling joint gets a water test at 1.5 times the design pressure. We also do an air tightness test at 1.1 times. It takes in three-directional movement. It compensates for heat expansion, settling, and installation errors. The limit rods give you two protections: pull-out prevention and tear prevention. It seals by itself with no leaks for a long time. You do not need welding to put it in. Upkeep is simple. It works for waste water, clean water, and oil. We support custom sizes from DN300 to DN1200. Stock is ready and shipping is fast. Our factory is 10,000 square meters with 50 workers. We check every unit before shipping. We give a 24-month warranty.
