Molded Rubber Coupling Joints

Our Molded Rubber Coupling Joint gives you high pressure safety and pull-out prevention. We use it in city water supply, fire systems, pump stations, and chemical lines where safety matters most. We have been making pipe parts for over 20 years. This molded rubber coupling joint has a stable build and full protection. It is a safe choice for high safety level pipes. We use EPDM or NBR high-elasticity rubber. We use a four-layer mixing process with one-piece mold vulcanization. The flanges are clamp type forged steel with limit rods and protective covers.

This thing works from -20℃ to 120℃. It handles pressures from PN6 to PN16. Each molded rubber 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 and stops pipe stress. The limit rods control the max movement precisely. They stop water hammer and impact from pulling or tearing the joint. The seal has no dead corners and gives you no leaks for a long time. It cuts vibration and noise very well. It protects pumps, valves, and fans. It goes in fast with no welding and is simple to keep up. Our standard sizes are in stock. We give a 24-month warranty.
