Landefeld hose fittings Germany Landefeld model Landefeld price

Landefeld hose fittings connect different hydraulic components to form a closed-loop hydraulic system, serving as a connecting accessory. They connect various hydraulic components (pumps, delivery lines, directional valves, shut-off valves, hydraulic motors, hydraulic cylinders, and auxiliary components such as level gauges, thermometers, and pressure gauges) to form a closed-loop hydraulic system, acting as a connecting accessory.

Landefeld hose fittings application

Pneumatic quick-connect fittings are quick connectors mainly used for air piping and pneumatic tools. They 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 both the male and female bodies. The valves in both the male and female bodies close, instantly blocking fluid flow. For two-way shut-off quick air hose 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 type ring can completely prevent fluid leakage.

Quick-connect fittings are also known as self-locking fittings or quick-insert sealed fittings. They allow securing pipes and fittings with simple operation, without needing nuts or clamps. They can withstand high pressures, 70Bar or even higher. Flanged ports or straight round pipes in cooling water channels usually require clamps for standard fittings, which involves more steps and has lower pressure resistance. With technological progress, besides self-locking quick-connect fittings, pneumatic quick-connect fittings (automated quick-connect fittings) are better suited for industrial automation production, using pneumatic drive. The purpose of using quick-connect fittings is faster operation; modern mechanized production emphasizes efficiency and reducing operator workload. Their speed is reflected in: easy handling, fewer steps, simple operation, automatic locking, and sealing/disconnection requiring only one plug-in and one pull-out, which is much more convenient than standard fittings.

Landefeld hose fittings advantages

1, High joint strength: Based on the principle of cold work hardening of steel, the strength of the straight threads rolled on the rebar is significantly improved, making the tensile strength of the straight thread joint higher than that of the base rebar material. 2, Stable performance: The connection process is not affected by worker skill levels, ensuring stable performance. 3, Fast connection speed: Since off-site prefabrication and on-site assembly are used, rebars with pre-threaded ends can be mass-produced and stored in the rebar yard. When the schedule is tight, only additional assembly workers are needed at the construction site. 4, Wide application range: There are basically no restrictions in application; it is more suitable for scenarios where rebars cannot rotate, such as bent rebars, fixed rebars, and rebar cages. 5, Easy management: Mismatch between sleeves and rebars will not occur, and inspection is convenient. Operation is simple; ordinary workers can become skilled after a few hours of training. 6, Significant economic and social benefits: Shortens construction cycles, improves engineering quality, reduces energy consumption, benefits environmental protection, reduces equipment investment, and has low additional costs, offering clear economic and social benefits. 7, Low labor intensity: Processing one threaded end requires only one step on a dedicated thread rolling machine.
