Selecting the right nylon cable gland might sound like a small detail, but for engineers and procurement specialists, it’s often the difference between a safe, efficient installation and costly downtime. Whether you’re designing electrical panels for automation equipment, marine enclosures, or solar junction boxes, knowing the correct nylon cable gland size chart is essential.
Let’s explore everything B2B buyers and technical teams need to know — from sizing and materials to compatibility and certification — so you can make the right call for your next project.
A nylon cable gland (also known as a plastic cable gland or PA6 gland) is a mechanical device that secures cables through enclosure walls or electrical equipment. It seals the entry point, protecting against dust, moisture, and tension that can damage the cable connection.
Engineers prefer nylon for several reasons:
That’s why nylon cable glands are common in control cabinets, solar systems, robotics, and LED lighting — essentially anywhere durability and safety meet cost-efficiency.
Choosing the wrong size isn’t just an inconvenience — it risks cable slippage, poor sealing, and failed IP ratings. The nylon cable gland size chart helps you identify which gland corresponds to your cable’s outer diameter (OD), ensuring a tight fit that maintains IP68 (or higher) protection.
If you’re buying for industrial or OEM use, size consistency also means streamlined installation, less rework, and lower supplier variability.
Below is a general size reference for common metric-thread nylon glands. Actual dimensions may vary slightly by manufacturer, but this table provides a reliable guideline for engineers and procurement teams comparing specs.
| Gland Type | Thread Size (Metric) | Cable Diameter Range (mm) | Dome Nut Outer Diameter (mm) | Mounting Hole (mm) | Length (mm) |
|---|---|---|---|---|---|
| M12 | M12×1.5 | 3–6.5 | 17.6 | 12.2 | 22 |
| M16 | M16×1.5 | 4–8 | 22.3 | 16.2 | 24 |
| M20 | M20×1.5 | 6–12 | 26.8 | 20.2 | 27 |
| M25 | M25×1.5 | 11–16 | 32.9 | 25.2 | 28.5 |
| M32 | M32×1.5 | 15–20 | 40.4 | 32.2 | 30 |
| M40 | M40×1.5 | 19–28 | 50.1 | 40.3 | 31 |
| M50 | M50×1.5 | 27–35 | 59.3 | 50.3 | 35 |
| M63 | M63×1.5 | 34–44 | 72.4 | 63.3 | 38 |
Pro tip: always measure your cable’s outer diameter with precision before selecting the gland — not its nominal size.
Choosing a gland isn’t just about picking a number from a chart. For engineers and supply-chain specialists, several technical parameters must align:
For B2B buyers comparing material types, it’s helpful to see how nylon stacks up against brass or stainless steel glands.
| Feature | Nylon Cable Gland | Brass Cable Gland |
|---|---|---|
| Material | Polyamide (PA6) | Nickel-plated brass |
| Weight | Very light | Heavier |
| Corrosion Resistance | Excellent | Good (may require coating) |
| Cost | Low | Moderate to high |
| Application | Indoor, light-duty, plastic enclosures | Outdoor, industrial, metal housings |
| Installation | Tool-free | Requires wrench |
Verdict: For panel builders, solar projects, and equipment exports, nylon cable glands often balance protection, durability, and value perfectly.
Engineers rely on nylon cable glands across many industries:
When sourcing, always confirm the operating environment and seal performance to ensure long-term reliability.
Technical datasheets often include values like “M20×1.5, Ø6–12mm, PA6, IP68, UL approval.” Here’s how to interpret that quickly:
If you’re specifying in bulk, keep a size chart PDF handy to cross-check stock availability and ordering codes from your supplier.
Even the best gland can fail if installed improperly. Keep these quick installation steps in mind:
Avoid over-torquing — it can deform the nylon threads and reduce sealing efficiency.
If you’re purchasing nylon cable glands in bulk for OEM production or resale, look for suppliers who offer:

A 10mm cable typically fits an M20 nylon cable gland, which covers a 6–12mm range.
Yes, most quality nylon glands are IP68-rated, offering dustproof and waterproof protection.
Absolutely. UV-stabilized nylon glands perform well in outdoor and solar applications.
They generally withstand –40°C to +100°C, and some reach +120°C depending on grade.
While PG threads are older German standards, you can compare similar sealing ranges using a nylon cable gland size conversion chart from your supplier’s resources.
When it comes to managing cables in industrial settings, cost is always a major concern. Choosing between nylon cable glands and plastic cable glands is often the first decision to make for procurement teams looking to balance quality and budget. Both materials offer distinct advantages, but which one is the smarter choice for price-sensitive projects? Let’s take a close look at […]
