Hasco announces that new screw plugs Z9410 with collar are available in a brass version with an FKM O-ring, and in a high-temperature version made of stainless steel. The O-ring, which in the HT version consists of a high-temperature-resistant FKM material, ensures reliable sealing of the temperature control bores, even without an additional thread seal.
Both screw plugs are suitable for process-reliable temperature control of injection molds with hot or cold water or heat transfer oil. The low compression set enables optimal use, with production downtimes thanks to minimized leaks. The screw plugs are easy to assemble and disassemble.
Screw plug Z9410 is made made of brass material 2.0401 and can be used for temperatures up to 120°C with water and oil. Alternately, the operating temperatures for the HT version made of stainless steel 1.4305 with high-temperature O-rings are included up to 180°C for water and 220°C for oil. Hasco says they ensure reliable tightness even with large temperature differences, and are ideal for applications in medical and cleanroom technology.
