Installing the right cable gland ensures safe, long-lasting electrical connections. At Volt Metal Industries, we help you select and fit single compression cable glands, double compression cable glands, PG cable glands, and more. Here’s an easy guide to get it right every time.

1. Choose the Right Type for Your Needs

First, identify the best cable gland style:

• Single compression gland: One seal – simple, quick to install.
• Double compression gland: Two seals – for extra protection against dust and moisture.
• PG cable gland: Popular, standardized sizes (PG7, PG9, PG11, etc.) – ideal when you need off-the-shelf sizing options.

Match the gland type to your cable’s environment and protection needs.

2. Match Gland Size to Cable Diameter Accurately

Measure your cable’s outer diameter precisely – using calipers if you can. Pick a gland that fits snugly. A misfit can lead to poor sealing, exposing your system to moisture or mechanical stress.

3. Always Check Manufacturer’s Instructions

Each cable gland type – whether you’re using Volt Metal or any other supplier—comes with fitting instructions. Reading them carefully prevents common mistakes, ensures safe installation, and preserves warranty coverage.

4. Ground Armored Cables Properly

When you’re working with armored or metallic-sheathed cables, ensure proper grounding through the gland. A grounded setup avoids unsafe electrical potentials and keeps your system stable.

5. Tighten Carefully – Don’t Over-Torque

Tighten by hand or with a torque wrench, following the torque guidelines. Over-tightening can crack the gland or damage the cable; under-tightening can result in poor sealing. Find that balance.

6. Handle Sealing Components with Care

For double compression glands, take care when fitting the inner and outer seals. Misaligned or mispressed seals may fail to keep out dust, water, or oil. Align seals properly, and compress gently but securely.

7. Inspect Thoroughly After Installation

Always give your work a final check. Make sure:

• The gland sits flush and firm.
• Seals look even and undamaged.
• There are no visible gaps or exposed cables.
• Grounding (for armored types) is correct.

This final review helps prevent future faults and ensures the installation remains reliable.

Why Proper Installation Matters

• Reliable protection: A well-fitted cable gland keeps out water, dust, chemicals, and strain.
• Longer equipment lifespan: Proper sealing prevents wear and corrosion.
• Safety first: Including grounding reduces electrical risks.
• Professional appearance: Clean, secure installs reflect high standards – perfect for industrial and commercial settings.
