Hydraulic Quick Coupler leak prevention

In the hydraulic system, both the metal pipe fitting, or hose fittings, there are prone to leakage problems. For ferrule fittings, mostly due to pipeline subject to greater external force or impact, so that the card sleeve loose or deformed face caused by leaking pipe, you should check whether the card holder out of round, whether the defect edge, whether the pipe ends intact and nut, compression level, etc., while also eliminating pipeline force. For flared fittings, mostly due to excessive flaring, quality, undesirable or multiple demolition, resulting in flared cracks or deformation caused by leaks, then you can be re-flared front truncated. hydraulic manifold block If you use a male and female cone top pressure seal, the leakage is mostly due to two cone damage, available on the cone abrasive grit grinding.
      In some with "о" or outer-ring face seal by the occasion, the leakage following reasons: "о" ring aging or deformation caused by leakage; "о" ring assembly is not in place, so that the two plane connection when pressure is uneven or "о" ring being cut cause leakage; "о" rings uncompacted, elastic deformation caused by insufficient leakage; "о" spigot ring groove too deep and cause leaks. In this regard, the need to re-select the same diameter and cross-sectional thick "о" rings can also be sealed with a rabbet plane for cutting grooves or grinding to reduce the rabbet groove depth, so that "о" rings are flexible enough to deformation (compression should generally be between 0.35-0.65mm).
     For the use of oil and rubber, wool felt, soft steel cardboard, combined sealing gasket or sealant leaking pipe joints, whether any material, you should first check the seals for damage, deformation, aging and rough through the large, etc. and then take the appropriate measures.
