WEGENER hose connectors Germany WEGENER model WEGENER price

WEGENER hose connectors are components in hydraulic systems that connect high-pressure oil hoses to other high-pressure oil hoses. Hydraulic pipe fittings can be further classified into hydraulic hoses, high-pressure ball valves, quick-connect couplings, compression-type pipe fittings, welded pipe fittings, high-pressure hoses, transition pipe fittings, tee pipe fittings, non-standard pipe fittings, flare-type pipe fittings, right-angle pipe fittings, rotary pipe fittings, quick-connect couplings, stainless steel pipe fittings, and copper fittings.

WEGENER hose connector classification

Inert gas type, mainly used for vacuum piping and compressor pressure resistance tests. Both the sleeve and plug have built-in automatic shut-off valves suitable for vacuum applications, maintaining a vacuum level of 1.3×10Pa in the disconnected state. Precautions for use: Do not exceed the maximum operating pressure limit during use. Do not use outside the specified temperature range to prevent wear or leakage of sealing materials. Do not subject to artificial impact, bending, or stretching to prevent damage. Do not connect or disconnect under pressure or residual pressure. Do not disassemble. Use sealant for tapered pipe threads on external threads. Do not subject to artificial impact, bending, or stretching to prevent damage. Do not use with fluids other than the specified compatible fluids. Do not use for purposes other than quick-connect couplings. Do not connect with quick-connect fluid couplings from other manufacturers. Do not use in environments containing metal powder, sand, or dust to prevent malfunction or leakage. Attachment of debris will cause malfunction or leakage. A brake valve must be installed before the quick-connect coupling. Do not use as a hinge joint. Use in machinery with vibration or shock will reduce durability. Cold water and oil types are mainly used for general-purpose mold interfaces. They thoroughly simplify mold interchange operations, enhance rust prevention, and come in various types. Precautions for use: Note: Do not use with fluids other than the specified compatible fluids. Do not exceed the maximum operating pressure limit during use. Do not use outside the specified temperature range to prevent wear or leakage of sealing materials. Do not subject to artificial impact, bending, or stretching to prevent damage. Do not use in environments containing metal powder, sand, or dust to prevent malfunction or leakage. For threaded installations, do not exceed the maximum tightening torque during installation to prevent damage. Do not use cracked hoses to prevent leakage or detachment. Use in machinery with vibration or shock will reduce durability. The working fluid must be clean fluid filtered through a filter. Do not disassemble quick-connect couplings. Semiconductor types are mainly used for semiconductor and fluororesin semiconductor production equipment and devices. The body material should be made of corrosion-resistant metal or molded fluororesin (PFA) all-resin products. Precautions for use: Note: Perform leaching tests of sealing materials with the fluid to confirm material compatibility. Use Teflon sealing tape for external tapered pipe threads. Do not exceed the maximum tightening torque when installing threads to prevent damage. To reduce friction (insertion load) and protect the "O"-shaped sealing ring during insertion, apply the working fluid or pure water to the "O"-shaped sealing ring or the quick-connect coupling (the folded part of the "O"-shaped sealing ring). During disconnection, since a small amount of fluid flows out, compressed air can be used to discharge the fluid inside the quick-connect coupling before separation to prevent hazards. Do not use as a hinge joint. Do not use for purposes other than quick-connect fluid couplings. Do not subject to artificial impact, bending, or stretching to prevent damage. Do not pressurize sleeves or quick-connect couplings individually to prevent the valve from flying out. When used individually, the specified dust cap must be installed. Do not disassemble quick-connect couplings.

WEGENER hose connector installation precautions

Pipe threads must meet requirements; threading should be completed in two passes, using coolant during machining. Machine threads to standard specified dimensions, clean away chips remaining on the threads or pipe ends, and apply rust inhibitor to the thread surface for corrosion protection and sealing. The engagement length of threaded connections should be tightened with a pipe wrench after adjusting the force with the pipe fitting's threaded connector. After connecting pipes and fittings, apply rust-preventing sealant or zinc-rich paint to exposed threaded parts, all tool marks, and surface damage. If threaded connector heights differ, do not install them reversed. Locking methods must be reliable. For bolt structures subjected to bending moments, minimize thread loading to avoid bending stress on the bolts. Threaded holes should not pass through two welded parts. For deep threaded holes, design corresponding bosses on the parts. The heads of fastening bolts for high-speed rotating bodies should not protrude.

WEGENER hose connector functions

Insert the steel tube into the ferrule and tighten it with the ferrule nut. The ferrule bites into the tube to create a seal. No welding is required when connecting to steel tubes, which is beneficial for fire prevention, explosion protection, and high-altitude work, and eliminates drawbacks caused by improper welding. The mechanical advantages and geometry of the fitting make this mechanical device a leak-proof sealing component. The mechanical thrust pushes the rear ferrule against the conical back of the front ferrule, while simultaneously pushing the front ferrule into the conical tapered mouth of the fitting body. The ferrule is squeezed onto the conduit by an inward radial force. At this point, pulling out the front ferrule forms a full-face seal on the conical tapered surface of the fitting body. When hand-tightening feels secure, rotate the ferrule nut further from this hand-tight position to ensure uniform thrust on the seal. This ensures effective sealing even in high-pressure and ultra-high vacuum environments. Therefore, it is a relatively advanced connector in pipeline systems for self-control devices in oil refining, chemical, petroleum, natural gas, food, pharmaceutical, and instrumentation systems.
