Riegler hose fittings Germany Riegler model Riegler price

Riegler hose fitting is a type of hose fitting mainly composed of three components. Metal hose fittings are used in many places. The main component of the metal hose fitting, the bendable part, is made of braided metal wire. Metal hose fittings offer excellent performance and come in a wide variety. Different types of metal hose fittings have different characteristics, structures, and maximum temperature ratings.

Riegler hose fitting classification

The structural forms of fittings are generally divided into three major categories: 1, Screw-type: For metal hose fittings with nominal diameters below 50 mm operating under high working pressure, screw-type connections are predominantly used. When the threads are tightened, the internal and external tapered surfaces of the two fittings mate closely to achieve sealing. The cone angle is generally 60 degrees, though 74 degrees is also used. This structure provides good sealing, but concentricity of the two mating parts must be ensured during installation. To address common issues in practical engineering such as repeated assembly/disassembly and difficulty in achieving concentricity, the fitting can be designed with a tapered surface mating with a spherical head. 2, Flange-type: For metal hose fittings with nominal diameters above 25 mm operating under general working pressure, flange-type connections are predominantly used. They seal via a tongue-and-groove mating arrangement. A loose flange, capable of radial rotation and axial sliding, connects the two bodies under the tension of tightening bolts. This structure offers good sealing performance but is difficult to manufacture, and the sealing surfaces are prone to damage. For special applications requiring rapid disconnection, the holes for the tightening bolts can be slotted to create a quick-release flange. 3, Quick-disconnect type: For various metal hose fittings with nominal diameters below 100 mm, quick-disconnect types are generally used where rapid assembly and disassembly are required. They commonly use an "O"-shaped sealing ring made of fluoroplastic or special rubber. When the handle is moved through a certain angle, it acts like the claws of a multi-start thread being locked; the tighter the "O"-shaped sealing ring is compressed, the better the sealing performance. This structure is most suitable for fire scenes, battlefields, and other situations requiring rapid installation and removal. A set of fittings can be connected or disconnected within seconds without any special tools.

Riegler hose fitting usage

When using different hoses, hose fittings are required for connection. There are various types of hose fittings, and the connection method generally involves crimping with a hose crimping machine. The specific procedure is to select the hose, cut it to size, strip the hose cover, install the hose fitting, crimp it with the hose crimping machine, clean off any rubber debris, and then install the dust cap, sealing ring, and retaining ring. Connecting hose fittings to hoses is not difficult, but attention must be paid to ensuring effective sealing. The following introduces how to ensure sealing when connecting hose fittings to hoses. One, What is a hose fitting? When using different types of hoses, a specialized fitting must be equipped for normal operation. A hose fitting is the component that connects the hose. There are generally multiple types, including those with 24° flare-type bite-type fittings, spherical joint fittings or same-angle conical surface fittings, bite-type tube connection fittings, 60° conical angle connection fittings, hollow hose screw connection fittings, and threaded connection fittings with or without sealing grooves.

Riegler hose fitting selection

A tee fitting, as the name implies, is a pipe fitting with 3 openings. This hardware component can transport and separate gases and liquids. Tee fittings have widespread applications, such as in water pipe repairs under non-shutdown conditions and in metal hose pipeline systems. 1, Check suitability: The selection of tee fittings first depends on the actual condition of the water pipe. The shapes and specifications of three-way fittings vary. They are mainly divided into T-shape or Y-shape, with equal-diameter and different-diameter nozzles. Equal-diameter nozzles have three ports of the same diameter. Generally, the reducer is larger than the main pipe, and 2 pipes are smaller than the main pipe. You can choose according to your actual needs and select accessories compatible with the pipeline, preferably from the same brand. 2, Check material: The materials for water pipe tee fittings mainly include carbon steel, cast steel, carbon steel, stainless steel, copper, aluminum alloy, plastic, argon arc casting, pvc, etc. Different materials have different prices and applications; everyone can choose based on their own situation. Buy now, but regardless of the material, check whether it is qualified first. You can smell for any unpleasant odors. If purchasing carefully, you can check the product qualification mark. 3, Check appearance: When purchasing tee fittings, pay attention to their appearance, checking for smoothness, uniform pipe wall thickness, and cleanliness. Do not choose "accessory" grade pipes. If it is a threaded tee fitting, also pay attention to whether the external thread development and pitch are uniformly distributed. 4, Check performance: Performance is the direct standard for product adoption; too low performance will affect service life. You can immerse the tee fitting in boiling water. If you find that the water pipe loses its initial strength, its performance is not very good.
