Double-ball Rubber Joints, made of NR, SBR, IIR, NBR, EPDM, CR, MVQ, FKM, has heat resistance, acid or alkaline resistance, corrosion resistance, wear resistance, and oil resistance. Double-ball Rubber Joints, made from inside layer, enhanced layer with multi-layer plastic scratch nylon cord fabric, and outer rubber tubes. There are many raw materials, such as NR, SBR, IIR, NBR, EPDM, CR, MVQ, FKM, etc. So it has heat resistance, acid or alkaline resistance, corrosion resistance, wear resistance, and oil resistance.  Attention:1. During the installation, over-displacement limit installation is forbidden.2. The bolts should in balance, gradually pressurized and screw. 3. If the work pressure is over 1.6MPa, elastic pressure pad must be used when install, in case of the partial reveal.4. The installation site should be away from heat, ozone field, strong light radiation exposure and undesirable medium are forbidden, and so on.1. Products Name: Double-ball Rubber Joints2.
