Nylon Nut Advantages
- 75% lighter than metal nuts
- Does not cold-weld in saltwater
- Insulating properties prevent galvanic corrosion
- Maintains torque at -40°C to +120°C
Installation Guidelines
- Hand-tighten plus 1/4 turn with wrench (3-5 Nm torque)
- Use dielectric grease on threads in marine environments
- Armor must be properly grounded at termination point
Technical FAQs
Q: Why choose nylon over metal coupling nuts?
A: Prevents galvanic corrosion when connecting to stainless steel sensors.
Q: Maximum pull tension during installation?
A: 250N (56 lbf) with armor engaged.
Q: Does nylon degrade in UV exposure?
A: UV-stabilized material maintains strength for 10+ years outdoors.
Q: Can I replace just the coupling nuts?
A: No, nuts are molded to cable during manufacturing.
Q: Difference between -00 and -02 suffix?
A: -00 = Metal nuts, -02 = Nylon nuts.
