Hose connector JB1885-77 what is the standard?
The reason of high pressure hose joint leakage are the following: "a" ring aging or deformation caused by leakage; the "C" ring assembly is not in place, the two plane connection or "C" uneven pressure ring is cut caused by leakage; "a" ring without compaction, the elastic deformation caused by leakage; the "C" ring spigot groove deep caused leakage. In this regard, the need to re select the same diameter and thick section "C" ring, can also be provided with a sealing plane rabbet groove of cutting or grinding, in order to reduce the rabbet groove depth, the "C" ring has enough elastic deformation (compression should be between 0.35-0.65mm).
The pipe joint oil sheet, wool, steel board, combined sealing washer or sealant leak, whatever the material, should first check the seal is damaged, and rough conditions such as deformation, aging, and then take corresponding measures.
