High pressure hose fittings leak reasons: high pressure hose fittings leak following reasons: "о" ring deformation caused by aging or leakage; "о" ring assembly is not in place, so that when connecting two planes uneven pressure or "о" ring being cut cause leakage; "о" ring uncompacted, insufficient amount of 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 of various hydraulic hose fittings can also be sealed with a flat spigot groove cutting or grinding to reduce mouth just groove depth that "о" ring has enough elastic deformation (compression should normally be between 0.35-0.65mm). For the use of oil and rubber, wool felt, soft steel cardboard combination gasket sealant joints or pipe leaks, no matter what the material is a hydraulic hose fittings factory, we should first check whether the damaged seal hydraulic hose fittings, deformation and aging and rough through the large production of hydraulic hose fittings, etc., and then take the appropriate measures. Use of hydraulic hose fittings: This connector is suitable for oil, water and air as media sites. Nominal pressure 320kgf / cm2, medium temperature -30 ℃ 200 ℃ Material: Carbon Features: 1) unique design allows the ends firmly clasp yin and yang together valve automatically opens at both ends, in the nominal range of fluid remains smooth. 2) Disconnect both ends of the spool automatically shut down to prevent fluid spill. 3) key parts quenching, greatly improving the pressure resistance and abrasion resistance. 4) The standard seal material is NBR, high temperature Viton 5) This product complies with ISO5675 standards 6) can also be customized according to customer requirements and processing.
