1. The use medium of rubber joints: water, weak acid and alkali, oil, etc. According to different mediums, natural rubber joints, EPDM rubber joints, nitrile rubber joints, neoprene rubber joints, etc. are selected.
2. The operating temperature of rubber joints: -15~80℃, especially up to -20~120℃. According to the working temperature, natural rubber joints, EPDM rubber joints, PTFE-lined rubber joints, etc. should be selected.
3. The pressure of the rubber joint: 0.6MPa, 1.0MPa, 1.6MPa, 2.5MPa, 4.0MPa, different pressures determine whether the rubber joint needs a limit device.
4. For the installation length of the rubber joint, select the appropriate length of the rubber joint according to the site installation requirements, including single-ball, double-ball, threaded and other rubber joints.
5. The connection mode of the rubber joint: flange connection, threaded connection, the connection mode is different, you can choose the rubber joint of flange connection or threaded connection.
