Stainless steel cable gland play a key role in cable entry protection for industrial equipment. They ensure a secure connection, seal out dust and moisture, and provide excellent strain relief. When selecting a cable gland, the thread type is one of the most important considerations — especially for markets that follow American standards. That’s where the NPT Thread Stainless Steel Cable Gland becomes the ideal solution.

In this guide, we will explain what NPT threads are, why they are widely used in stainless steel cable glands, and how to choose the right gland for demanding industrial environments.

✅ What Is NPT Thread?

NPT stands for National Pipe Thread, which is a standard widely used in the United States, Canada, and other regions following ANSI/ASME pipeline specifications.

Key features:

• Tapered thread structure for stronger sealing performance
• Excellent mechanical holding force
• Designed for secure fitting with PTFE/Teflon tape

✅ Why Use NPT Thread in Stainless Steel Cable Glands?

Stainless steel, especially SS304 and SS316, offers excellent corrosion resistance and durability. Combined with NPT tapered threading, it enhances performance in extreme working conditions.

Main benefits:

• Highly reliable waterproof sealing (IP67/IP68)
• Strong resistance to chemicals, saltwater, and oil
• Excellent performance in vibration and heavy-duty environments
• Compliant with UL / NEC industrial requirements

✅ Where Are NPT Stainless Steel Cable Glands Used?

They are suitable for multiple industries requiring high safety standards:

✅ How to Choose the Right NPT Stainless Steel Cable Gland

When selecting an NPT cable gland, you must match both thread size and cable diameter:

Common NPT sizes:

• 1/4″, 3/8″, 1/2″, 3/4″, 1″, 1-1/4″, 1-1/2″, 2″

Other key selection factors:

• Cable outer diameter range (OD)
• Sealing inserts: EPDM / Silicone / Viton
• Armored vs. non-armored cable options

✅ Installation Tips for Better Performance

To ensure maximum sealing efficiency:

✔ Apply PTFE sealing tape
✔ Tighten using proper torque values
✔ Ensure correct alignment to avoid thread damage
✔ Inspect sealing surface before installation

✅ Quality Standards & Compliance

Look for certified stainless steel cable glands for industrial projects:

• UL Listed
• CE & RoHS
• Ingress Rating: IP67 / IP68
• Resistant to fire, dust, and chemical exposure
