Dungs hose fittings Germany Dungs model Dungs price

Dungs hose fittings are widely used in high-pressure piping applications in industrial fields, such as ships, offshore oil, metal processing, and mining. Flared tube fittings are suitable for hydraulic, lubrication, high-pressure water flushing, and high-pressure air pipelines. Flared tube fittings have been certified by many auditing agencies; they offer high reliability, inherent cleanliness, and strong flexibility, with faster and simpler pre-processing assembly and installation. Flared connections require no welding, saving subsequent processes such as pickling and flaw detection. Flared tube fittings are a type of quick-connect fitting suitable for various pipe fittings and pipes with a nominal pressure not exceeding 32MPa. According to the manufacturer, flared connections are widely used in industries such as oil refining, chemical, light industry, textile, national defense, metallurgy, aviation, automotive, pharmaceutical, machinery, shipbuilding, natural gas, and CNG refueling stations.

Dungs hose fitting applications

Pneumatic quick-connect fittings are primarily used for air piping and pneumatic tools. These fittings allow pipeline connection or disconnection without tools. When disconnected—when the sleeve of the female body moves to the other end—the stainless steel balls automatically roll outward, and the male body disconnects under the combined spring force of the valves in the female and male bodies. The valves in the male and female bodies close separately, instantly blocking fluid flow. For double-shut-off air hose quick-connect fittings: when connected, as the male body is inserted into the female body, the sleeve returns to its original position under spring action, and the steel balls roll to lock the male body tightly. Simultaneously, the valves in the female and male bodies push against each other to open, allowing fluid flow. The O ring can completely block fluid leakage.

Dungs hose fitting manufacturing process

It includes a sealing ring, a connecting part, and a union nut for connecting the pipe. Therefore, the sealing ring is designed as a ring cutter with one or more cutting edges. By screwing the union nut onto the connecting part, the ring cutter can be inserted into the hole cavity of the connecting part, which has a conical surface. The outside of the sealing ring has an annular reinforcement on the nut side. This annular reinforcement forms an annular surface at the transition zone towards the narrow ring part. The inclination of said annular surface formed by the reinforced part of the ring cutter relative to the pipe axis is 45°-90°. When fully assembled, the axial length of the annular reinforcement allows the transfer element arranged on said annular surface to transfer its own negative image structure or itself onto the end face of the connecting part. The transfer element has a three-dimensional contour, the negative image of which can be transferred onto the surface of the connecting part. Similar to using a mold, the assembler applies pressure to imprint the negative image onto the surface of the connecting part.
