OMAL hose fittings Germany OMAL model OMAL price

OMAL hose fittings are pipe fittings and pipeline connectors. Also known as tee fittings, three-way fittings, or tee joints, they are used where branch pipes are required from the main pipeline. A tee is a chemical pipe fitting with three openings: one inlet and two outlets, or two inlets and one outlet. It comes in T shape and Y shape, with equal-diameter or reducing ports, used for the junction of three identical or different pipelines. The main function of a tee is to change the direction of fluid flow.

OMAL hose fitting selection

Y shape tee metal hose fitting, one end connects to thin-wall steel electrical conduit, and the other two ends connect to metal hoses via metal fittings: The metal fittings are die-cast from zinc alloy, with galvanized, matte, or chrome-plated surfaces; compact structure, no pores, high strength. Reliable connection with metal hoses, aesthetically pleasing; various non-standard metal hose fittings and special metal fittings can be customized. T shape tee metal hose fitting, one end connects to thin-wall steel electrical conduit, and the other two ends connect to metal hoses via metal fittings; the metal fittings are die-cast from zinc alloy, with galvanized, matte, or chrome-plated surfaces, compact structure, no pores, high strength. Reliable connection with metal hoses, aesthetically pleasing; 90 degree elbow fitting: Thread specification: After engagement with British threads, it forms a 90 degree angle with the enclosure box, made of thickened zinc alloy, aesthetically pleasing appearance, compact structure, high strength. In addition to the standard specifications below, sizes and thread standards can be arbitrarily changed according to requirements.

OMAL hose fitting classification

Welded pipe fittings, utilizing welding between the adapter and the pipe. End-face sealing between the fitting body and the adapter is achieved using an O shape sealing ring. Simple structure, easy to manufacture, good sealing performance, low requirement for pipe dimensional accuracy. High welding quality is required, and assembly/disassembly is inconvenient. Operating pressure can reach 31.5MPa, operating temperature -25 to 80°C, suitable for pipeline systems with oil as the medium. Compression-type pipe fittings, utilizing the deformation of the ferrule to grip the pipe and seal it. Advanced structure, good performance, light weight, small volume, convenient to use, widely used in hydraulic systems. Operating pressure can reach 31.5MPa, requiring high pipe dimensional accuracy and cold-drawn steel pipes. High ferrule precision. Suitable for pipeline systems with oil, gas, and general corrosive media as the medium. Flared pipe fittings, utilizing flaring at the pipe end for sealing, requiring no other sealing components. Simple structure, suitable for connecting thin-wall pipes, suitable for low-pressure pipeline systems with oil and gas as the medium. Insert-welded pipe fittings, inserting the pipe of the required length into the fitting until the pipe end contacts the inner end of the fitting, welding the pipe and fitting into one unit, eliminating the need for an adapter, but requiring strict pipe dimensions. Suitable for pipeline systems with oil and gas as the medium. Taper-seal welded pipe fittings, one end of the adapter has an external taper surface plus an O shape sealing ring matching the internal taper surface of the fitting body, tightened with threads. Operating pressure can reach 16 to 31.5MPa, operating temperature -25 to 80°C, suitable for pipeline systems with oil as the medium. Crimped hose fittings, easy to install, but adds a tightening process. After hose damage, the fitting outer sleeve cannot be reused; it forms an assembly with wire-braided hoses. Can be used in conjunction with welded pipe fittings sealed with O shape rings. Suitable for pipeline systems with oil, water, and gas as the medium. Medium temperature: Oil: -30 to 80°C; Air: -30 to 50°C; Water: below 80°C. Three-piece hose fittings, no need to strip the outer rubber layer of the hose during assembly. For hoses with slightly different outer diameters, compensation is achieved by the pre-compression of the hose by the fitting outer sleeve. The pre-compression of the hose in the range of 31% to 50% ensures no leakage under working pressure, no pull-out, and no rupture of the outer rubber layer. Can be used in conjunction with welded pipe fittings, quick-change fittings, and compression-type pipe fittings. Suitable for pipeline systems with oil, water, and gas as the medium. Its working pressure and medium temperature are limited by the connected hose. Quick-change fittings (two-end shut-off type), after the pipe is disconnected, it can self-seal, preventing loss of liquid in the pipeline, thus suitable for frequent disassembly occasions. Complex structure, significant local resistance loss. Suitable for pipeline systems with oil and gas as the medium, working pressure below 31.5MPa, medium temperature -20 to 80°C. Quick-change fittings (two-end open type), suitable for pipeline systems with oil and gas as the medium. Its working pressure and medium temperature are limited by the connected hose.

OMAL hose fitting usage

The connection between hose fittings and hoses is generally completed using a hose crimping machine. First, cut the hose to the required size, then strip the outer layer of the measured hose, install the hose fitting, and finally crimp it with the hose crimping machine. The specific steps are as follows: 1. Select the appropriate hose and cut it to the specified length. 2. Strip the outer rubber layer from both ends of the hose. 3. Select the appropriate type of hose fitting. 4. Install the fitting core (requires oil application) and the hose fitting outer sleeve in sequence. 5. Crimp with the crimping machine, paying attention to selecting the appropriate crimping amount. 6. After crimping is complete, clean the rubber debris from the inner wall of the hose, then install the dust cap, sealing ring, and retaining ring.
