How to choose Nylon Cable Glands, material advantages and misunderstandings

For industrial wiring or outdoor lighting, choosing the right cable gland model and material impacts equipment stability. Users often struggle with nylon-based glands—e.g., model matching, material doubts, or metal vs. nylon comparisons. This article answers these key questions to help you avoid pitfalls and understand nylon’s value.
 

How to Choose the Right Nylon Cable Gland Model?

Incorrect selection causes loose cables or protection failure. Focus on three core factors:
 

1.Match Inner Hole to Cable Diameter

Refer to product specs to avoid "too loose/too tight" issues:

2-5mm cables: Choose M8/PG7 (covers small diameters, seals dust/moisture).

10-18mm cables: Opt for M20/G1/2 (reasonable gap—no insulation damage or shaking).

≥20mm thick cables (e.g., industrial power lines): Use M30/PG29+ (some support up to 120mm diameter).

Note: Reserve 0.5-1mm error for cable insulation thickness.
 

2.Pick Protection Level & Thread Type

Harsh environments (outdoor, damp, dusty): Select IP68 (waterproof/dustproof for long-term immersion).

Thread matching: NPT (1/4"-2") for North America; G/PG threads for Europe/China. Wrong threads block installation or damage equipment.
 

Nylon vs. Brass/Stainless Steel: Core Advantages

Nylon outperforms metal in convenience, adaptability, and cost—ideal for small-batch, multi-scenario needs:
 

1.Lightweight & Easy to Install

Weight: 60% lighter than brass, 75% lighter than stainless steel (e.g., M20 nylon gland = 15g vs. 40g brass). Cuts shipping costs.

Installation: No heavy tools—use a regular wrench. Avoids scratching equipment/cables.
 

2.Corrosion-Resistant & Low-Maintenance

Metal flaws: Brass rusts in damp/acidic areas; stainless steel is costly/heavy.

Nylon benefits: PA66/PP nylon resists weak acids, salt spray, and -40℃~120℃ temps. 5+ year lifespan (30% longer than brass).
 

3.Cost-Effective & Flexible Inventory

Price: 1/3-1/2 of stainless steel, 20-30% cheaper than brass (saves initial investment for small batches).

MOQ: Low minimum orders + short production cycles. Reduces warehouse costs for SMEs.
 

Common Misunderstandings About Nylon Cable Glands

1.Poor Temperature Resistance?

Truth: Compliant nylon works for most industrial needs.

PA66 reinforced nylon: 150℃ short-term, -40℃~120℃ long-term (covers 80℃ max for most equipment).

Only extreme temps (>150℃, e.g., near furnaces) need special materials.
 

2.Weak Load-Bearing?

Truth: Meets conventional cable needs.

≤10mm cables: 5kg static load, 2kg dynamic load (fits equipment wiring/outdoor lights).
