NR Rubber Metal Flexible Joint in Pipes Class 150 Flanged Type
Rubber metal flexible joint in pipes, Certified to SAE J1404, ISO 1436, and other industry standards, these connectors balance flame-retardant properties (via halogen-free rubbers) with anti-static safety in explosive atmospheres. Unlike all-metal alternatives, they eliminate galvanic corrosion risks at dissimilar material junctions while offering superior noise/vibration reduction—key for marine, renewable energy, or compressed air systems prioritizing longevity and operational silence.

Note: 1. The special requirements of rubber metal pipe connector can be customized according to the user's drawing. Flange standard is GB / t9115.1-2000. Various flange standards (GB, JB, Hg, CB, ANSI, DIN, BSEN, NF, en, JIS, ISO, etc.) can be selected for production. The rubber ball of rubber metal pipe connector can be used as natural rubber, ethylene propylene diene monomer rubber, chloroprene rubber, butyl rubber, butadiene rubber, fluorine rubber, etc. When the rubber metal pipe connector above DN200 is used for suspended water supply, the pipe must have fixed support or fixed support, otherwise the rubber metal pipe connector shall be installed with anti falling device.
Typical installation
The installation in the piping of the anti-vibration joints near of pumps, compressors, control devices, valves, operating machines, etc., allows to interrupt the propagation of sound waves and to absorb small vibrations.
