How to Choose a Sealcon NPT Cable Gland

Start with the enclosure's NPT entry size, then match the gland's cable range to the cable's measured outside diameter. Select the body material for the surrounding environment and choose a specialty design only when the application requires shielding or hazardous-location compliance.

1. Match NPT thread 2. Verify cable OD 3. Check panel clearance 4. Select material and type

Material Selection Tips

Nylon supports lightweight general-purpose installations, with the black nylon also being UV rated for outdoor applications. Nickel-plated brass adds mechanical strength and is used for many EMI/RFI designs. PVDF suits applications where chemical resistance is important. Stainless steel is a strong choice for demanding washdown, outdoor and corrosive environments.

Important Sizing Note

The cable jacket diameter must fall within the listed clamping range. Do not select a gland from thread size alone. Also confirm through-hole diameter, thread length and body length against the enclosure wall thickness and internal clearance.

Common Applications for Sealcon NPT Dome Fittings

Sealcon NPT cord grips provide a secure transition where electrical cable enters an enclosure or piece of equipment. By gripping the cable and sealing around its outer jacket, the fitting helps prevent movement at the entry point, reduces strain on internal terminations and limits the intrusion of dust, moisture and other contaminants. This makes the fitting suitable for demanding industrial installations where cable protection and enclosure integrity must be maintained.
