When it comes to managing cables safely and neatly—whether in control panels, machines, or outdoor installations—PG glands play a key role. But with so many sizes and materials available, how do you choose the right one?
Let’s simplify it for you.
🔧 What is a PG Gland?
A PG gland, or Panzer-Gewinde gland, is a mechanical cable entry device. It’s used to:
Secure a cable into an enclosure or panel
Seal the entry point to protect against dust, water, and other contaminants
Provide strain relief to avoid cable damage
In short, it’s a small component that makes a big difference in electrical safety and installation quality.
📏 1. Choose the Right Size
PG glands come in different sizes (e.g., PG7, PG9, PG13.5, PG21, etc.). The right size depends on your cable’s outer diameter.
Here’s a quick reference:
| PG Size | Cable Range (mm) |
|---|---|
| PG7 | 3 – 6.5 mm |
| PG9 | 4 – 8 mm |
| PG13.5 | 6 – 12 mm |
| PG21 | 13 – 18 mm |
| PG29 | 18 – 25 mm |
| PG36 | 22 – 32 mm |
Always measure the cable jacket (outer layer) to pick the correct gland size.
🧱 2. Pick the Material: Plastic or Metal?
You’ll typically find PVC (plastic) and brass (metal) PG glands.
✅ Plastic PG Glands: Lightweight, corrosion-resistant, and suitable for indoor or light-duty use.
✅ Brass PG Glands: Stronger, offer better grounding, and ideal for industrial or outdoor environments.
For general electrical panels or indoor setups, PVC glands are a great choice. For heavy-duty or high-risk areas, go for metal glands.
💧 3. Check the IP Rating
PG glands often come with an IP rating (Ingress Protection). The higher the rating, the better the seal.
IP54 – Basic dust and splash protection (indoor use)
IP68 – Waterproof and dust-tight (outdoor or underground use)
Choose based on your environment. If the cable goes outside, exposed to rain or dust, go for IP68-rated glands.
🔗 4. Thread Type Matters
Most PG glands use PG thread, but some industrial applications may require metric or NPT threads.
Stick to PG-threaded glands if you’re using standard electrical enclosures or panels.
🛒 5. Buy From a Reliable Supplier
