ZOOK hose fittings Germany ZOOK model ZOOK price

ZOOK hose fittings consist of a nut, metal ring, sealing ring, and the body itself. They offer waterproofing, dirt resistance, explosion-proof protection, and corrosion resistance, becoming an essential part of industrial piping. Overall, each pipeline has different requirements for metal hoses; plastic-coated metal hose tee fittings and corresponding bimetallic composite pipes are used for different materials and construction environments.

ZOOK hose fitting classification

Welded pipe fittings, where the adapter is welded to the pipe. The joint body and adapter are sealed at the end face with an O-ring seal. Simple structure, easy to manufacture, good sealing performance, and low requirements for pipe dimensional accuracy. High welding quality is required, and assembly/disassembly is inconvenient. Working pressure up to 31.5MPa, working temperature -25～80℃, suitable for oil-based pipeline systems. Bite-type pipe fittings, which use the deformation of the bite sleeve to grip the pipe and seal. Advanced structure, good performance, lightweight, compact, easy to use, widely used in hydraulic systems. Working pressure up to 31.5MPa, requires high pipe dimensional accuracy and cold-drawn steel pipes. High bite sleeve precision. Suitable for oil, gas, and general corrosive media pipeline systems. Flared pipe fittings, which seal by flaring the pipe end, requiring no other sealing components. Simple structure, suitable for thin-walled pipe connections, applicable to low-pressure pipeline systems with oil or gas as the medium. Insert-welded pipe fittings, where the pipe of required length is inserted into the fitting until the pipe end contacts the inner end of the fitting, welding the pipe and fitting into one unit. This eliminates the need for an adapter but requires strict pipe dimensions. Suitable for oil and gas pipeline systems. Cone-seal welded pipe fittings, where one end of the adapter has an outer cone surface with an O-ring seal matching the inner cone surface of the joint body, tightened with threads. Working pressure up to 16～31.5MPa, working temperature -25～80℃, suitable for oil-based pipeline systems. Crimped hose fittings, easy to install but adding a tightening process. The outer sleeve cannot be reused if the hose is damaged; they form an assembly with wire-braided hoses. Can be used with welded pipe fittings sealed with O-rings. Suitable for oil, water, and gas pipeline systems. Medium temperature: Oil: -30～80℃; Air: -30～50℃; Water: below 80℃. Three-piece hose fittings, requiring no stripping of the hose outer cover during assembly. For hoses with slightly different outer diameters, compensation is achieved by the pre-compression of the hose by the outer sleeve. A pre-compression range of 31%～50% ensures no leakage under working pressure, preventing hose pull-out and outer cover rupture. Can be connected to welded pipe fittings, quick-change fittings, and bite-type pipe fittings. Suitable for oil, water, and gas pipeline systems; working pressure and medium temperature are limited by the connected hose. Quick-change fittings (two-end shut-off type): After disconnection, the pipes self-seal, preventing fluid loss, making them suitable for frequent disassembly. Complex structure with higher local resistance loss. Suitable for oil and gas pipeline systems, working pressure below 31.5MPa, medium temperature -20～80℃. Quick-change fittings (two-end open type): Suitable for oil and gas pipeline systems; working pressure and medium temperature are limited by the connected hose.

ZOOK hose fitting precautions

Do not use hose quick-connect fittings for purposes other than fluid transfer. Do not use with fluids other than the specified compatible fluids. Do not exceed the maximum operating pressure during use. Do not use outside the specified temperature range to prevent deformation of sealing materials, which can lead to leaks. Do not subject to artificial impact, bending, or stretching to prevent damage. Do not use in environments with mixed metal powder or sand/dust; while quick-connect fittings can be used in harsh conditions to ensure long service life, the presence of debris can cause malfunction or leakage. Do not disassemble the quick-connect fitting.

ZOOK hose fitting structure

Introduction to the structure and features of metal hose fittings: DGJ self-locking metal hose fittings connect unthreaded steel pipes or unthreaded equipment outlets to hoses, eliminating the threading process. The metal fittings are die-cast from zinc alloy, with galvanized, matte, or chrome-plated surfaces. Compact structure, high strength. Reliable connection between steel pipes and metal hoses, aesthetically pleasing. These self-locking metal fittings are used to connect metal hoses to unthreaded steel pipes or unthreaded equipment outlets. Compatible metal hoses: JS type, JSH type, JSB type, JSHG type. Compatible steel pipes: Thin-wall electrical conduit, black/white iron pipes (water/gas pipes). When selecting DGJ self-locking metal hose fittings, please note the specifications and dimensions of the connected steel pipes and hoses. Y-type three-way metal hose fittings: One end connects to thin-wall electrical conduit, while the other two ends connect to metal hoses. 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. Compatible metal hoses: JS type, JSH type, JSB type, JSHG type, full range of specifications. Custom non-standard metal hose fittings and special metal fittings are available.
