FAQ
How do I choose between PG, G and NPT threads?
Match the gland thread to your enclosure or conduit system: PG is common on European equipment, G is BSPP straight thread, and NPT is tapered for North American systems. Do not mix thread types in the same opening.
How do I ensure IP68 sealing?
Strip only the outer jacket where the seal grips, insert the cable fully, then tighten the cap nut until the EPDM seal is uniformly compressed. Avoid overtightening to protect threads and enclosure walls.
