Verder hose fittings Germany Verder model Verder price

Verder hose fittings consist of hollow screws, combination washers, and tubing connectors. They use hollow screws to compress two combination sealing gaskets against the connector body for sealing. This pipe fitting is a right-angle connector, characterized by adjustable piping direction, easy installation, and compact footprint. 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.

Verder hose fitting precautions

Before installation, all steel pipes may be pickled according to the requirements of Chapter 9, especially steel pipes connected with bite-type pipe fittings, which should be pickled first, and then the ferrule should be pre-tightened on the pipe end; (2) All pipe fittings should be cleaned with kerosene before installation, and the o ring seals inside should be temporarily removed and stored, to be installed during formal installation; (3) During construction, keep the oil ports of pumps, distributors, and other equipment, as well as the openings of pipe fittings and pipe ends, clean to prevent water, dust, and other foreign matter from entering; (4) Pipelines should be laid in a free state; excessive radial force must not be applied to forcibly fix and connect welded pipelines; (5) Check the oil holes of bearing housings in advance to ensure internal oil passages are unobstructed and that the oil port threads match the fittings.

Verder hose fitting examples

Geka coupling, Application: "Geka" couplings are specifically designed for low-pressure water pipes, serving as quick-connect fittings for garden and irrigation spray hoses. Structure: "Geka" quick-connect couplings have no male/female distinction and consist of left and right completely symmetrical "claw" structures. Sealing relies on rubber gaskets. The serrated tail design significantly increases friction with the water hose, offering simple and durable design. Pull-type coupling, Application: Designed and manufactured according to US military standards, suitable for quick connection of various fluid flexible and rigid hoses, composed of internal/external threads and male/female components. Wide material selection includes reinforced aluminum alloy, copper alloy, stainless steel, nylon plastic, etc., widely used in petrochemical and chemical transport fields. Structure: Pull-type quick-connect couplings consist of male and female parts. The male part has an arc shape to fit into the female part, which has a gasket at the bottom. Sealing is formed by pulling or pressing levers on both sides of the female part (small sizes have a lever on only one side) to press the male part against the gasket. Tanker truck coupling, Application: Quick-connect fittings, threaded connectors, and clamps for tanker trucks and container vehicles, developed entirely according to the German DIN series. Used at the end of tanker oil delivery pipes. Due to their simple and rapid operation design and zero-leakage stability, tanker truck series couplings have been popular in the European market for fifty to sixty years. Instrumentation quick-connect fittings, Leak-free O ring sealing can be used in vacuum and pressure systems and is interchangeable with others. Push-in connections enable quick and convenient operation, and large-area locking devices ensure a firmer grip on the hose stem. Full-flow quick-connect fittings, maximum working pressure 414 bar (6000 psig), made of stainless steel, carbon steel, and brass. Smooth, open internal cavity with no valves at either end minimizes pressure drop and facilitates cleaning.

Verder hose fitting applications

Pipe fittings are connection tools between pipes and detachable connection points between components and pipes. They play an indispensable role in pipe fittings and are one of the two main components of hydraulic piping. Pipe fittings are used for straight connections in instruments, with connection forms including socket welding or threaded connections. They are mainly used for small-diameter low-pressure pipelines, for parts requiring frequent assembly and disassembly, or as final adjustments for pipelines using threaded fittings. The structural form should preferably adopt metal-to-metal contact sealing; gasket sealing structures are typically used in general pipelines transporting water, oil, air, etc., and are manufactured from malleable cast iron. In addition, usage requirements and price are factors considered during selection. Pipe fittings come in many types; commonly used pipe fittings can generally be divided into rigid pipe fittings and hose fittings. If classified by the connection method between the fitting and the pipe, rigid pipe fittings include flared, bite-type (ferrule), and welded types, while hose fittings are mainly crimped hose fittings. In hydraulic systems, the connection methods between pipes and fittings also vary; the pipe insertion end uses connection threads. Tapered threads rely on their conical body tightening and sealing materials such as PTFE, mainly applied in medium- and low-pressure hydraulic systems. Fine-pitch threads provide excellent sealing and are frequently used in high-pressure systems, but they require combination washers or O rings for end-face sealing. Copper washers are sometimes used, suitable for pipes with thicker walls. Its main components include the connector body, sleeve, and nut. During use, the connector body is inserted into the target, and the aforementioned washers are used to seal the end face. Rubber sealing is used between the connector body and the sleeve, and spherical sealing is sometimes employed. As pipe fittings are detachable connection elements, in addition to meeting requirements for normal connection stability, strong sealing, reasonable dimensions, low pressure loss, and good process performance, they must also meet the requirement for convenient assembly and disassembly. Therefore, do not underestimate these small pipe fittings, as their existence supports the entire hydraulic system.
