NPT Nylon Cord Grip
An NPT Nylon Cord Grip is a threaded cable entry device designed to secure, protect, and seal electrical cords as they pass into enclosures or equipment. Featuring NPT (National Pipe Thread) threading, it is widely used in North American electrical systems and industrial installations.
Design & Structure
NPT Nylon Cord Grips are typically composed of:
Locknut or threaded body for secure mounting
Compression nut for easy tightening
Elastic sealing insert that adapts to different cable diameters
This structure allows the cord grip to maintain consistent holding force while accommodating minor cable size variations.
Why Choose NPT Nylon Cord Grips?
Compatible with standard NPT threaded openings
Protects cables from mechanical stress and abrasion
Lightweight yet mechanically strong
Resistant to corrosion and harsh industrial conditions
Cost-effective solution for professional wiring systems
| Feature | Nylon (PA66) | Metal (Brass/Stainless Steel) | Generic Plastics (PVC/PE) |

FAQ:
1: What is the difference between an NPT nylon cord grip and a standard cable gland?
An NPT nylon cord grip is primarily designed for strain relief and basic sealing, while some cable glands focus more on liquid-tight or EMC performance. Cord grips are commonly used to prevent cable pull-out and reduce mechanical stress on internal terminals, especially in flexible cable applications.
2: Are NPT nylon cord grips compliant with North American standards?
Yes. NPT threads are widely used in the United States and Canada. NPT nylon cord grips are designed to fit standard NPT threaded openings commonly found on electrical enclosures and junction boxes in North American installations.
3: What cable types can be used with NPT nylon cord grips?
They are suitable for round flexible cables, including power cords, control cables, and signal cables. The exact clamping range depends on the cord grip size and insert design.
