Leakage of the high-pressure hose fittings

High pressure hose joint leakage following reasons: "о" ring deformation caused by aging or leakage; "о" ring assembly is not in place, so that when the two planes uneven pressure connection or "о" ring is cut causing leakage; " о "ring uncompressed, less elastic deformation caused by leakage;" о "Mouth-ring groove too deep and cause leaks. In this regard, the need to re-select the same diameter and cross-sectional coarse "о" rings, also

You can seal the mouth with a groove on the plane were cut or grinding, in order to reduce the groove depth mouth only, so "о" ring has sufficient elastic deformation (compression should normally be between 0.35-0.65mm) . For the use of oil sheet, wool felt, soft steel board, combined sealing gasket or pipe joints leak sealant, No matter what the material, you should first check the seals without damage, deformation, aging and rough through the large, etc. and then take the appropriate measures.
