Los innovadores prensaestopas PRPRC, fabricados conforme a la normativa <b>DIN EN 62444 / 50262</b>, incorporan un sistema de <b>apriete laminar</b> y micro orificios laterales que <b>permiten la ventilación, la disipación del calor y el equilibrio de presión</b> en el interior del equipo. <br> Están equipados con una membrana interna oleofóbica e hidrofóbica fabricada en <b>PTFE</b>, que garantiza una <b>ventilación continua y un equilibrio de presión eficaz</b>. Esta tecnología ayuda a <b>evitar la acumulación de humedad y condensación</b>, limitando los incrementos no deseados de temperatura. Esto conlleva también una <b>mejor protección contra la corrosión</b> lo cual alarga la vida útil del equipo. <i>Las propiedades de la membrana no se ven afectadas por el <b>diámetro del cable</b> ni por su <b>torsión</b></i>. <br><br> Están fabricados en <b>Nylon 6 (PA6)</b>, e incluyen: <li>Una junta tórica plana de <b>NBR</b>.</li> <li>Una junta cilíndrica interior de Cloropreno <b>(CR)</b>, para el sistema de apriete laminar.</li> <br> Están disponibles con <b>rosca métrica</b> según <b>EN 60423</b> en los tamaños <b>M12 / M16 / M20</b>, y en colores: <b>RAL 9005</b> (Negro) / <b>RAL 7001</b> (Gris Oscuro) / <b>RAL 7035</b> (Gris Claro).

Por favor, consulte con nuestra oficina comercial.</i> <br><br> <b>Con un solo elemento obtienes dos ventajas: función prensaestopas + elemento intercambiador de aire.</b>   PRPRF flexible cable glands, manufactured according to <b>DIN EN 62444/50262</b>, allow the cable to move freely even continuously and offer excellent protection even when vibrations are present. The body is made of <b>PA6</b> (nylon6) and the internal seal of <b>CR</b> (Rubber - Chloroprene). It complies with IP66 and IP698 (up to 5 bar) type 4X (UL 50E) protection. For optimal sealing, we recommend using the lock nut (families <a href=' https://www.iscsl.co.uk/hexagonal-lock-nut-with-flange/prtu/ ' target='_blank'><b>PRTU</b></a>, <a href=' https://www.iscsl.co.uk/hexagonal-lock-nut/prtum/ ' target='_blank'><b>PRTUM</b></a>, <a href=' https://www.iscsl.co.uk/hexagonal-lock-nut/prtue/ ' target='_blank'><b>PRTUE</b></a>) and the flat section O-ring (<a href=' https://www.iscsl.co.uk/o-ring-for-metric-and-pg-threads/prp/ ' target='_blank'><b>PRP</b></a>), which are sold separately.<br>All three colours are UV resistant (F1 according to UL 746C).
