Our PRTU locknut is a hexagonal locknut with integrated flange for securing cable glands and accessories in electrical installations with metric connection threads according to EN 60423. The integrated flange increases the bearing surface and improves assembly stability, reducing stress on the mounting panel.

Manufactured in polyamide 6 reinforced with 30% glass fiber or in high-impact resistant polyamide 6, it is suitable for mechanically demanding applications and environments subject to vibration. The high-impact version is exclusively available for references 015008 in metric sizes M16, M20 and M25.

· Colours: light grey RAL 7035, dark grey RAL 7001, black RAL 9005; white RAL 9010 and red RAL 3000 for references 015008
· Metric threads: M12–M63 (EN 60423)
· PG threads: PG7–PG48

Other colours available on request.

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). Todos ellos son <b>resistentes a los rayos UV (F1 según UL 746C)</b>. <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='
