Hydraulic union fittings types is use in DIN 24 degree cone, JIC 37 flare tube, ORFS tube end, BSP 60 degree cone tube end etc hydraulic line connections, this is union type of hydraulic fitting catalog, you will find combination connection of hydraulic tube , hose and pipe connection in machinery.
As this picture showed: Hydraulic tube couplings connection with 24 degree cone system (referred to as DKO) bore form W according to DIN 3861 and ISO 8434-1. Hydraulic Straight thread adaptors union types bite hydraulic pipe fittings, also called cutting ring fittings and flareless fittings. It is assemble with union nut, cutting ring(ferrule), fitting body.
OEM hydraulic union fittings, Tee body weld in fixed plate.
Here is video will explain how we produce high quality of hydraulic adapter fittings as follows:
Technical advantages of this connection are:
