NON-DETACHABLE END FITTING FOR HIGH-PRESSURE HOSE

摘要

FIELD: transport and automobile industries; farming. SUBSTANCE: non-detachable fitting has circular projection on nipple which is shifted relative to inner circular projection on coupling towards rubber layer by amount of thickness of hose skeleton. Circular projections on nipple and on coupling have form of right-angled trapezium whose right angle is located on side opposite to rubber layer. Skeleton of hose is provided with paint-and-varnish coat with abrasive material applied before deformation of coupling. EFFECT: enhanced reliability of joint. 4 cl, 2 dwg
