When David, a procurement manager from a major automotive manufacturer in Detroit, called me last month, he was frustrated. “Samuel, I’ve been sourcing PG16 cable glands for our new production line, but half the suppliers can’t even explain the basic sizing requirements properly. We need precision, not guesswork.”
PG16 metal cable glands are designed for cables with outer diameters ranging from 10-14mm, featuring M16×1.5 threading and providing IP681 waterproof protection. These standardized cable entry solutions ensure reliable sealing and strain relief in industrial applications where durability matters most.
As someone who’s spent over a decade in the cable gland industry, I’ve seen too many projects delayed because of improper sizing. That’s why I’m sharing this comprehensive technical guide – to help you make informed decisions and avoid costly mistakes. 😉

What Are PG16 Metal Cable Glands?
PG16 cable glands represent a standardized cable entry solution following German DIN standards, specifically designed for medium-duty industrial applications.
The “PG” designation stands for “Panzer-Gewinde2” (armored thread in German), while “16” indicates the nominal thread diameter of 16mm. These glands feature M16×1.5 metric threading and accommodate cable diameters from 10mm to 14mm, making them versatile for various industrial cables.

At Bepto, we manufacture PG16 glands in three primary materials: brass for standard applications, stainless steel 316L3 for corrosive environments, and nickel-plated brass for enhanced durability. Each material serves specific environmental requirements while maintaining the same dimensional standards.
The beauty of PG16 glands lies in their standardization. Unlike proprietary sizing systems, PG threading ensures compatibility across different manufacturers – though quality can vary significantly. That’s where our rigorous quality control and ISO9001 certification make the difference.
How Do You Determine the Right PG16 Size?
Proper PG16 sizing requires measuring your cable’s outer diameter and ensuring it falls within the 10-14mm range, while considering jacket material and environmental factors.
Here’s my proven three-step sizing process that I’ve refined over years of customer consultations:
Step 1: Measure Cable Outer Diameter
Use precision calipers to measure the cable at its widest point, including any outer sheathing or armor. For oval cables, measure both dimensions and use the larger measurement. Add 0.5mm tolerance for manufacturing variations.
Step 2: Verify Thread Compatibility
Confirm your equipment accepts M16×1.5 threading. Some older equipment might use imperial threads or different metric pitches. I once helped Hassan, an operations manager at a petrochemical facility in Dubai, avoid a costly mistake when he nearly ordered PG16 glands for equipment that required NPT threading4.
Step 3: Consider Environmental Factors
- Temperature extremes: Standard PG16 glands handle -40°C to +100°C
- Chemical exposure: Stainless steel 316L for acids, brass for general use
- Vibration levels: Consider strain relief requirements
- IP rating needs: PG16 achieves IP68 with proper installation
Common Sizing Mistakes to Avoid
- Ignoring cable tolerance: Cables can vary ±0.5mm from specifications
- Overlooking armor diameter: Armored cables require larger gland sizes
- Mixing thread standards: PG16 is metric M16×1.5, not 16mm NPT
- Underestimating environmental factors: Chemical compatibility matters
What Materials Work Best for PG16 Applications?
Material selection for PG16 cable glands depends on environmental conditions, with brass offering cost-effectiveness, stainless steel providing corrosion resistance, and nickel-plated brass delivering enhanced durability.
Brass PG16 Cable Glands
Our brass PG16 glands use CW617N brass5 (58% copper, 39% zinc, 3% lead), providing excellent machinability and corrosion resistance for standard industrial environments. The natural antimicrobial properties of brass make it ideal for food processing and pharmaceutical applications.
Best for: General industrial use, indoor installations, moderate temperature applications
Avoid when: High salt exposure, acidic environments, temperatures above 100°C
Stainless Steel 316L PG16 Glands
316L stainless steel offers superior corrosion resistance with low carbon content preventing carbide precipitation. The molybdenum content (2-3%) provides excellent resistance to chlorides and marine environments.
Best for: Chemical processing, marine applications, high-temperature environments
Consider cost: 3-4x more expensive than brass but justified for harsh conditions
Nickel-Plated Brass PG16 Options
Our nickel plating process applies 8-12 micron coating thickness, providing enhanced corrosion protection while maintaining brass’s excellent conductivity and machinability.
Best for: Moderate corrosive environments, cost-sensitive projects requiring better protection than standard brass
Limitations: Plating can wear in high-vibration applications
How Do You Install PG16 Cable Glands Properly?
Proper PG16 installation requires correct torque application (12-15 Nm), adequate thread engagement (minimum 5 threads), and proper sealing ring compression for IP68 protection.
Installation Process
- Prepare the cable: Strip outer jacket to expose conductors, leaving 15-20mm of jacket for gland grip
- Thread sequence: Install locknut, sealing washer, then gland body
- Panel mounting: Ensure 8-10mm thread engagement through panel
- Cable insertion: Push cable through until jacket seats properly in sealing area
- Tightening: Apply 12-15 Nm torque to compression nut using proper spanner
Critical Installation Points
The sealing ring must compress evenly around the cable jacket. Over-tightening can damage the cable jacket, while under-tightening compromises IP rating. I always recommend using a calibrated torque wrench rather than “feel” – it’s saved countless installations from premature failure.
Testing Your Installation
After installation, perform these verification steps:
- Visual inspection for even sealing ring compression
- Gentle cable pull test (50N force maximum)
- IP rating verification using appropriate test equipment
- Documentation of installation torque values
