• Finish Type: Look for a nickel-plated finish for enhanced corrosion resistance.

Size and Compatibility

Finding the Right Fit

Selecting the correct size for your brass cable gland is vital to avoid issues like cable strain or inadequate sealing. Here’s what to check:

• Cable Diameter: Measure the outer diameter of the cable accurately.
• Gland Size Options: Ensure the gland can accommodate various sizes; typically, sizes are available based on the cable's outer diameter.
• Thread Type: Make sure the thread type (metric or NPT) matches your equipment’s requirements.
