In the industrial sector, steel wire reinforced spray hoses made of synthetic rubber not only possess excellent oil resistance, heat resistance, and aging resistance, but are also suitable for use in various harsh environmental conditions. Therefore, their quality is particularly important. Below, let's take a look at the requirements for the tapered seal used in this type of hose. 1. The tapered angle for connecting steel wire reinforced spray hoses is 60 degrees, and the pipe end taper angle should generally be 1 degree smaller than the hole taper angle. 2. The pipe end must maintain a sharp edge and must not be inverted. 3. The thread direction between the pipe end and the lock nut should be opposite to that of the external threaded connector. 4. When machining connectors for high-pressure hoses, a small drainage hole should be retained at the sealing point. This prevents high-pressure water leakage in case of an imperfect tapered seal, serving both as a safety warning and facilitating observation and differentiation, thereby better protecting the sealing surface from damage. The above are the requirements for the tapered seal used in steel wire reinforced spray hoses. The quality of the joint seal greatly affects product leakage. Only by strictly following the specified sealing procedures can the sealing effectiveness of the hose be ensured. The tapered seal is one of the most frequently used joint sealing methods, so it is crucial to master it well.
