Locknut · 3/4 in NPT · Flanged black polyamide · ITC Electrical 184.175
3/4 in NPT flanged locknut in black polyamide for securing threaded cable gland and fitting connections in panels and enclosures. The flanged profile provides a larger bearing surface that can help improve grip and accommodate minor panel irregularities.
What this product is for
This 3/4 in NPT flanged locknut is used to secure compatible threaded cable glands and fittings to panels, boxes, and enclosures in commercial and industrial electrical installations.
Use for
Use for 3/4 in NPT threaded entries where a non-metallic locknut is required or preferred. Commonly used with plastic cable glands, control panels, junction boxes, and enclosure wall penetrations.
Avoid for
Avoid using this locknut with mismatched thread types such as metric or PG threads, or where a metallic bonding locknut is required by the installation design or code. Confirm thread compatibility before ordering.
Best for
Best for electricians and panel builders needing a black flanged locknut for 3/4 in NPT cable gland assemblies, especially where corrosion resistance and a wider contact surface are useful.
Installed in
Typically installed in control cabinets, machine panels, electrical enclosures, and equipment housings. For a 3/4 in trade size, the thread size is the key buying detail; metric conversion is generally not used for NPT selection.
Why this product exists
The flanged design increases contact area against the panel surface, which can help with retention and fit on cutouts with minor irregularities. ITC lists its plastic locknuts for corresponding gland thread sizes and notes that sealing can be improved with an additional sealing washer where required.
Compared with similar products
Compared with a non-flanged locknut, this style provides a larger bearing surface. Compared with metal locknuts, polyamide locknuts are commonly chosen where a non-metallic accessory is preferred for plastic cable gland assemblies. Actual suitability depends on the fitting, enclosure material, and installation requirements.
