5. Selection & Installation Guidelines
- Match the cable diameter range according to the actual outer diameter of the cable, preferably within the middle interval to ensure sealing and clamping force.
- Select the thread according to the equipment interface; prefer the original thread of the equipment to avoid reducing the protection level with adapters.
- EPDM or silicone seals are recommended for outdoor, high-humidity, and salt-spray environments; NBR seals for oil-resistant applications.
- Tighten the compression nut evenly during installation; avoid over-tightening to prevent damage to nylon threads. Use O-rings and gaskets to ensure IP68 sealing.
