During the use of the card sleeve connector, leakage may occur, so we can take relevant measures to prevent such phenomena from happening. The leakage prevention measures are as follows:

For sleeve joints, leakage is often caused by the loosening of the pneumatic ball valve sleeve or deformation of the pipe end face due to significant external or impact forces on the pipeline. At this time, it is necessary to check whether the sleeve is out of roundness, whether the cutting edge is damaged, whether the pipe end is intact, and the degree of compression of the sleeve nut. At the same time, external forces on the pipeline should also be removed. For expansion type pipe joints, leakage is often caused by excessive expansion, substandard quality, or repeated disassembly, resulting in deformation or cracking of the expansion. In this case, the front end can be cut off and re expanded.

Re select the "о" ring with the same outer diameter and thicker cross-section, or cut or grind the sealing surface with a stop groove to reduce the depth of the stop groove and provide sufficient elastic deformation for the "о" ring. When there is a leakage at the pipe joint using oil resistant rubber plate, wool felt, soft steel cardboard, combined sealing gasket or sealant, regardless of the material, the sealing element of the sleeve joint should be checked for damage, deformation, aging and excessive roughness, and then corresponding measures should be taken.
