perma-tec hose fittings Germany perma-tec model perma-tec price

perma-tec hose fittings consist of hollow screws, combination washers, and oil pipe connectors. They use hollow screws to compress two combination sealing gaskets onto the connector body for sealing. This pipe fitting is a right-angle connector, characterized by the ability to freely adjust the direction of piping, easy installation, and small space occupation. The operating pressure is less than 32 MPa. Pipe fittings are detachable connectors used to connect pipes, between pipes, and between hydraulic components. The connection threads of pipe fittings can be standard fine threads or tapered threads; tapered threads are commonly used in medium and low-pressure systems, while standard fine threads are commonly used in high-pressure systems.

perma-tec hose fitting usage

When using different types of 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 up 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 a proper seal. Below, we introduce how to ensure sealing when connecting hose fittings and hoses. Let's take a look. First, what is a hose fitting? When using different types of hoses, a special fitting must be equipped for normal operation. A hose fitting is the component that connects hoses. There are generally many types, including those compatible with 24 ° flare-type ferrule fittings, spherical joint fittings or same-angle conical surface fittings, ferrule-type pipe connection fittings, fittings with 60 ° conical angle connections, hollow hose screw connection fittings, and threaded connection fittings with or without sealing grooves.

perma-tec hose fitting precautions

Do not use quick-release hose fittings for applications 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 easily lead to leaks. Do not subject the fittings to artificial impact, bending, or stretching to prevent damage. Do not use in environments contaminated with metal powder, sand, or dust. Using quick-release fittings in such conditions can ensure long service life under harsh operating conditions. Accumulation of debris can cause malfunction or leakage. Do not disassemble the quick-release fittings.

perma-tec hose fitting installation

Dual-line main and branch pipes: From the lubrication pump to the oil inlet of all distributors, these lines withstand relatively high pressure. Cold-drawn seamless steel pipes are usually used, made of 10 or 15 steel. Pipes with severe rust must never be used. Oil supply pipes: From the distributor to the oil inlet of all lubrication points (bearing housing oil holes), these lines withstand relatively low pressure. Drawn copper pipes are usually used, as they are easy to route when bending. Cold-drawn seamless steel pipes or stainless steel pipes are also used. Hose fittings are used for connections at moving parts. Piping should avoid areas with high-temperature radiation or cooling water spray, where temperatures are too high or too low, especially at hose fittings. Piping should not interfere with the operation of the host machine and other equipment; it must be safe, reliable, and convenient for work, observation, and maintenance. Piping should be horizontal and vertical, neat, and aesthetically pleasing. Minimize bends or small-angle bends; use large arcs to reduce oil flow resistance. If conflicts occur during installation, smaller pipes should yield to larger pipes, and low-pressure pipes should yield to high-pressure pipes. Pipes crossing each other must not touch and should be separated by a certain distance. Connectors on parallel pipes should be staggered to avoid affecting installation and removal. To facilitate disassembly and cleaning, union joints should be installed appropriately, but their use should be minimized to reduce the possibility of leakage. Determine the pipe length on-site based on the piping path determined by 8.2 items, paying attention to the influence of the bending radius. Consider the impact of inserting various different pipe fittings into the pipeline. Pipe lengths should be determined, cut, and pre-assembled segment by segment to facilitate on-site adjustments according to actual conditions. If all pipes are cut at once, accumulated errors will make piping difficult. Utilize cut short pipes wherever short sections are needed. If necessary, straight couplings can be used to extend length, but the number of joints on a pipe section should be minimized.
