BRAUNWARTH hose fittings Germany BRAUNWARTH model BRAUNWARTH price

BRAUNWARTH hose fittings consist of hollow screws, combination washers, and oil pipe connectors. They seal by using hollow screws to press two combination sealing gaskets against the connector body. 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 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.

BRAUNWARTH hose fitting usage

How to ensure sealing in the connection between hose fittings and hoses? The connection between hose fittings and hoses is simple, but ensuring the seal is critical. So, how is the seal achieved in the connection between hose fittings and hoses? Generally, regardless of the variety of hose fittings, one must select the appropriate transition joint based on the type of hose fitting. If the hose is a standard water hose, use a transition joint with an internal thread on one end and a hose insert on the other, secured with a hose clamp. If both ends of the hose have internal threads, use a transition joint with an internal thread on one end and an external thread on the other. If both ends of the hose have external threads, use a straight-through internal thread connector. Hydraulic quick-change couplings generally need to withstand high pressure, so in most cases, high-pressure oil hoses are used. Both ends of the oil hose usually have internal threads, allowing for direct connection. As for hydraulic fittings, no other rubber rings are needed for sealing; the product itself has one concave end and one convex end, achieving a complete seal upon connection.

BRAUNWARTH hose fitting installation precautions

Pipe threads must meet requirements. Threading should be completed in two passes, using coolant during machining. Process threads to the dimensions specified by standards. Clean away chips remaining on the threads or pipe ends, and apply rust preventive agent to the thread surface for corrosion protection and sealing. The engagement length of threaded connections should be tightened with a pipe wrench to adjust the torque. After connecting pipes and fittings, apply rust-preventive sealant or zinc-rich paint to exposed threads, all tool marks, and surface damage. Do not install backwards when thread heights differ. 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.

BRAUNWARTH hose fitting selection criteria

1, fluid type, and temperature (please select quick couplings with body and sealing materials suitable for the fluid type and temperature). Depending on the fluid, suitable body and sealing materials vary. For example, for air, steel quick couplings are recommended; for water, choose brass or stainless steel. 2, liquid pressure (please select quick couplings with pressure resistance suitable for the fluid pressure). Fluid pressure is also key to selecting quick couplings. Hydraulic quick couplings are standardized in the range of 5.0Mpa (51kgf/cm&²) to 68.6Mpa (700kgf/cm&²). Corresponding to pressure resistance characteristics, the structure of quick couplings also varies. 3, automatic shut-off valve structure (please select quick couplings with valve structures suitable for piping applications). Valve structures include two-way shut-off, single-way shut-off, and two-way open types. Note that except for two-way shut-off types, fluid will flow out from the piping upon disconnection. 4, usage environment of the quick coupling (please select quick couplings with structures and materials suitable for the usage environment). Consider the humidity, dust conditions, and corrosiveness of the environment when selecting the type, body material, and sealing material of the quick coupling. 5, confirm that the connection threads of the selected quick coupling are consistent. When using products from different brands, it is best to use male and female ends from the same brand. If cross-brand use is necessary, consult the supplier's technical staff before use to confirm compatibility. 6, installation shape and dimensions. Determine the model and material of the quick coupling, and specify the assembly shape and dimensions corresponding to the piping characteristics. Note that dimensions are related to fluid flow rate.
