Causes of leaks in camlock coupling
Main reason of camlock coupling leakage as following:
1.Share a seal ring, regardless of turning off or turning on the gas. Sealing ring on both sides by the pressure, the apron deformation is serious, easy to damage; when turn off the gas, the spool circular surface in the spring force and high pressure gas under the common role of rubber soft joint and bowl-shaped seal linear contact. Sealing pressure increases, not easy to leak, while the bowl-shaped seal network back with a seat flange seat, not easy to shift, small deformation. When venting, the male connector opens the spool. The purpose of the camlock coupling is to connect the gas source quickly and easily. In China, both the automobile manufacturing industry, household electrical appliance manufacturers, or maintenance of self-employed, are a lot of use of 
compressed air as a power source, therefore, will use the gas quick connector. It can be said that as long as the power will be used, and if the use of time is not long on the leak, will waste energy consumption, increase production costs.
2.The rubber soft connector male end face and apron face contact, sealing pressure is relatively small, coupled with uneven end face, it is easy to leak.
