FAQ
How do I choose between standard and long-thread metric cable glands?
Use standard thread for typical sheet-metal or plastic walls. Choose long-thread (L) when the panel is thicker or when extra thread engagement is required with locknuts and washers.
What torque should I apply to ensure IP68 sealing?
Tighten by hand, then use a wrench until the EPDM seal is fully compressed. Do not overtighten; follow your enclosure supplier’s torque guideline to avoid cracking.
