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 withhold hydraulic hose fittings, so that when the two planes connected uneven pressure or "о" ring is cut cause leakage; "о" ring uncompressed hydraulic hose fittings, lack of elastic deformation caused by leakage; "о" just too deep mouth-ring groove and cause leaks. In this regard, the need to re-select the same diameter and cross-sectional coarse "о" rings, can also be sealed with a flat spigot groove cutting or grinding to reduce mouth groove on the depth h hydraulic hose fittings 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 outside buckle hydraulic hose fittings, seals should first check whether the damage, deformation, aging and rough too large, etc., and then take the appropriate measures.
