LEISTER hose connector Germany LEISTER model LEISTER price

LEISTER hose connectors consist of hollow screws, combination washers, and oil pipe fittings. They seal by using hollow screws to press two combination sealing washers against the connector body. This pipe fitting is an elbow connector, characterized by adjustable piping direction, easy installation, and compact space requirement; operating pressure is less than 32 MPa. Pipe fittings are detachable connectors used between pipes and hydraulic components. Connection threads can be standard fine-pitch threads or tapered threads; tapered threads are commonly used in medium- and low-pressure systems, while standard fine-pitch threads are commonly used in high-pressure systems.

LEISTER hose connector forming method

The hot-push elbow forming process uses a dedicated elbow pushing machine, mandrel, and heating device to push the blank mounted on the die forward. During movement, it is heated, expanded, and bent into shape. The deformation characteristic of hot-push elbows follows the principle that metal volume remains constant before and after plastic deformation to determine the tube blank diameter; the selected tube blank diameter is smaller than the elbow diameter. The mandrel controls the blank's deformation, causing compressed metal at the inner arc to flow and compensate for other areas thinned by expansion, resulting in uniform wall thickness. The hot-push elbow forming process offers aesthetic appearance, uniform wall thickness, and continuous operation, making it suitable for mass production. Thus, it has become the primary forming method for carbon steel and alloy steel elbows, and is also applied in forming certain specifications of stainless steel elbows. Heating methods during forming include medium-frequency or high-frequency induction heating (heating coils can be multi-turn or single-turn), flame heating, and reverberatory furnace heating; the choice depends on product requirements and energy availability.

LEISTER hose connector functions

Exchange function: accessories for pneumatic and hydraulic tools, cylinders, hydraulic cylinders, and metal mold-related machinery. Maintenance function: cooling systems for computers, maintenance of die-casting machine hydraulic cylinders. Testing function: testing for vacuum, pressure resistance, leakage, and operation. Conveying function: transport and handling of solids such as bolts and nuts, as well as electrical conductivity. Filling function: inert gases, nitrogen, PG, carbonic acid. Connection function: fixtures for fishing rods and portable CD players, connections for mobile operations, and applications beyond fluid transfer. Time and labor saving: quick disconnect and connection of oil lines with simple actions, saving time and manpower. Oil saving: when oil lines are disconnected, the check valve on the quick connector seals the line, preventing oil outflow and avoiding loss of oil and pressure. Environmental protection: no oil spillage during quick connector disconnection and connection, protecting the environment. Modular equipment for easy transport: large equipment or portable hydraulic tools can be disassembled using quick connectors for transport and reassembled at the destination. Economic value: the above advantages create economic benefits for customers.

LEISTER hose connector advantages

Ferrule-type copper pipe fittings—advantages: simple structure, reliable sealing performance, ease of use, precision manufacturing, and lightweight, aesthetic design. No gaskets or welding required, saving material and offering good performance for repeated assembly and disassembly. Since stainless steel ferrule fittings cannot be welded, pipeline impurities have less impact on system performance. Therefore, stainless steel ferrule pipe fittings are increasingly widely used in hydraulic and pneumatic equipment pipelines using oil and gas as media, especially suitable for environments with fire hazards, high-altitude work, and frequent assembly/disassembly. They are currently being vigorously promoted and used in China. Ferrule-type copper pipe fittings—structure and principle: the basic structure is simple, consisting of only three basic parts: the connector body, ferrule, and nut. The main component is the ferrule, a metal ring with a cutting edge at the front. International standard GB3764-83 recommends a unified I type shape for the cutting edge.
