RESCUE TAPE hose fittings German RESCUE TAPE models RESCUE TAPE prices

RESCUE TAPE hose fittings are connecting devices used to join metal hoses and pipes. Their model numbers are typically determined by factors such as material, connection method, size, and applicable working pressure. Different models have different characteristics and scopes of application, such as bite-type metal hose fittings, flange-type metal hose fittings, and swivel metal hose fittings. Selecting the appropriate metal hose fitting model requires consideration of multiple factors, such as the temperature, pressure, fluid medium, service life, and connection method of the working environment. For applications under special operating conditions such as high temperature, high pressure, and strong corrosion, it is necessary to select high-quality metal hose fitting models that meet the requirements.

RESCUE TAPE hose fitting precautions

Hoses must not be bent excessively during movement or when stationary, nor bent at the root; bending should start at least 1.5 times the diameter away from the root; hoses should not be pulled too tight when moved to extreme positions and should remain relatively slack; avoid twisting deformation of the hose as much as possible; keep hoses as far away from heat-radiating components as possible, installing heat shields if necessary; avoid external damage to the hose, such as long-term friction against component surfaces during use; if the hose's own weight causes excessive deformation, support brackets should be used.

RESCUE TAPE hose fitting classification

Welded pipe fittings utilize welding between the adapter and the pipe. End-face sealing between the fitting body and the adapter is achieved using an O-ring seal. The structure is simple, easy to manufacture, offers good sealing, and does not require high precision in pipe dimensions. High welding quality is required, and assembly/disassembly is inconvenient. Working pressure can reach 31.5MPa, working temperature -25 to 80°C, suitable for pipeline systems using oil as the medium. Bite-type pipe fittings use the deformation of the ferrule to grip the pipe and create a seal. They feature an advanced structure, good performance, light weight, small size, and ease of use, and are widely used in hydraulic systems. Working pressure can reach 31.5MPa, requiring high precision in pipe dimensions and the use of cold-drawn steel pipes. Ferrule precision is also high. Suitable for pipeline systems with oil, gas, and general corrosive media. Flared pipe fittings use the flared end of the pipe for sealing, requiring no other sealing elements. The structure is simple, suitable for joining thin-walled pipes, and applicable to low-pressure pipeline systems using oil and gas as media. Insert-welded pipe fittings involve inserting the pipe into the fitting until the pipe end contacts the inner end of the fitting, then welding the pipe and fitting into one unit. This eliminates the need for an adapter but requires strict pipe dimensions. Suitable for pipeline systems using oil and gas as media. Cone-seal welded pipe fittings feature an outer cone surface on one end of the adapter paired with an O-ring seal against the inner cone surface of the fitting body, tightened with threads. Working pressure can reach 16 to 31.5MPa, working temperature -25 to 80°C, suitable for pipeline systems using oil as the medium. Crimped hose fittings are easy to install but add a crimping step. The fitting outer sleeve cannot be reused after hose damage, and they are assembled with wire-braided hoses to form complete assemblies. They can be connected to welded pipe fittings sealed with O-rings. Suitable for pipeline systems using oil, water, and gas as media. Medium temperatures: Oil: -30 to 80°C; Air: -30 to 50°C; Water: below 80°C. Three-piece hose fittings do not require stripping the outer rubber layer of the hose during assembly. For hoses with slightly different outer diameters, compensation is achieved through the pre-compression of the hose by the fitting outer sleeve. A hose pre-compression range of 31% to 50% ensures no leakage under working pressure, preventing hose pull-out and outer layer rupture. They can be connected to welded pipe fittings, quick-change couplings, and bite-type pipe fittings, suitable for pipeline systems using oil, water, and gas as media, with working pressure and medium temperature limited by the connected hose. Quick-change couplings (two-way shut-off): After the pipe is disconnected, it seals automatically, preventing loss of liquid in the pipeline, making them suitable for frequent disconnection applications. The structure is relatively complex, resulting in higher local resistance loss. Suitable for pipeline systems using oil and gas as media, with working pressure below 31.5MPa and medium temperature -20 to 80°C. Quick-change couplings (two-way open): Suitable for pipeline systems using oil and gas as media, with working pressure and medium temperature limited by the connected hose.
