SIKLA hose fittings Germany SIKLA model SIKLA price

SIKLA hose fittings are straight-through connectors used for linear connections such as instruments. Connection methods include socket welding or threaded connection. They are mainly used for small-diameter low-pressure pipelines, for parts that require frequent assembly and disassembly, or for final adjustment of pipelines using threaded fittings. Relevant products are all listed by Kuaiyiyou. The structural form should preferably adopt a metal-to-metal contact sealing structure. The gasket sealing structure is generally used in general pipelines transporting water, oil, air, etc., and is made of malleable cast iron. In addition, application requirements and quotation are also factors to consider during selection. Straight-through hose fittings have a wide variety. Commonly used straight-through hose fittings can generally be divided into hard hose straight-through fittings and soft hose straight-through fittings. If classified according to the connection method between the straight-through hose fitting and the pipeline, hard hose straight-through fittings include flared type, ferrule type, and welded type, while soft hose straight-through fittings are mainly crimped rubber hose straight-through fittings. The connection methods for pipelines and straight-through hose fittings in hydraulic systems also differ; the pipe insertion end uses connecting threads. Tapered threads rely on their tapered body tightening and use materials such as polytetrafluoroethylene for sealing operations, and are mainly used in medium and low-pressure hydraulic systems.

SIKLA hose fitting installation

Cleaned pipelines should be formally installed and greased as soon as possible. Connect all pipeline sections segment by segment according to the printed matching marks, and tighten all pipe fittings. Note that the originally removed o O-rings must be reinstalled. All piping fixtures must be secure and not loose. All oil supply pipes can be connected to the distributor outlet and lubrication points after greasing. Metric general threads are indicated by uppercase M. Metric general threads are divided into coarse-pitch general threads and fine-pitch general threads according to pitch. Coarse-pitch general thread markings generally do not indicate the pitch, for example, M20 indicates coarse-pitch thread. Fine-pitch thread markings must indicate the pitch. General threads are used for connection and fastening between mechanical parts. General thread connections mostly use coarse-pitch threads. Fine-pitch threads have slightly higher strength than coarse-pitch threads of the same nominal diameter and better self-locking performance. Pipe threads sealed with threads can prevent leakage without adding filler or sealing material. Pipe threads sealed with threads have two connection forms: cylindrical internal thread and conical external thread, and conical internal thread and conical external thread. The former connection is sufficiently tight, while the latter connection is usually only adopted under high temperature and high pressure conditions.

SIKLA hose fitting classification

1, DPJ connector type, also known as DPJ external thread end-connection metal hose fitting, is an end-connection type used to connect metal hoses to enclosures as a linear connector. 2, DKJ connector, DKJ ferrule-type metal hose fitting, is a ferrule type used to connect metal hoses to steel pipes without threads, allowing connection of threadless steel pipes to hoses, eliminating the threading process, requiring only screwing in the screw. 3, DGJ connector, DGJ self-fixing metal hose fitting, is a self-fixing hose fitting used to connect metal hoses to threadless steel pipes or threadless equipment cable outlets, eliminating the threading process. 4, 90 degree elbow connector, follows the imperial thread standard. A, C, F parts are all made of high-quality steel, and the D part is made of die-cast iron sheet. The color is silver-white metallic. The operating temperature is between -40 degrees and 100 degrees. 5, Y shape connector, Y shape three-way metal hose fitting, its form is one end connector connecting to thin-wall steel electrical conduit, and the other two ends metal connectors connecting to metal hoses. 6, T shape connector, T shape three-way metal hose fitting, similar to the Y shape three-way metal hose fitting, its form is one end connector connecting to thin-wall steel electrical conduit, and the other two ends metal connectors connecting to metal hoses. 7, stainless steel connector, stainless steel hose fittings adopt end-connection type, cast from standard stainless steel, with compact structure, high strength, and reliable connection with hoses.

SIKLA hose fitting precautions

Open type: When the mold connector and mold water nozzle in high-pressure water hose quick connectors are in an open state, in the unconnected state, when the copper sleeve on the female head is pushed to the other end, the steel balls will automatically roll outward, causing the male head to be pulled out. In this case, since neither the male head nor the female head has valves, fluid will flow out. In the connected state, the male head is inserted into the female head, and the copper sleeve is pushed back to its previous position by its spring force, locking the steel balls, allowing fluid flow. The O O-ring therein will prevent fluid from flowing out. Combined type water hose quick connector: When the mold water nozzle in high-pressure water hose quick connectors is in an open state and the mold connector is in a closed state, in the unconnected state, the copper sleeve in the female head will move to the other end, and the stainless steel balls will automatically roll outward. The male head is opened by the reaction force of the valve spring, at which point the valve automatically closes to block fluid flow. In the connected state, the male head is inserted into the female head, and the copper sleeve is pushed back to its previous position by its spring force, locking the steel balls, allowing fluid flow. The O O-ring in the high-pressure water hose quick connector will prevent fluid from flowing out.
