Nylon Cable Gland Manufacturer — PA66, IP68 Rated, UV-Stabilised
Nylon Cable Glands — Factory-Direct Supply, CE & RoHS Certified
When you need a cable gland that’s lightweight, chemically resistant, and built to hold its seal outdoors over the long term — nylon is the right choice. Our nylon cable glands are made from PA66 polyamide, UV-stabilised for outdoor use, flame-retardant to UL94 V-2, and rated IP68 — tested to IEC 60529 on every production batch. They’re available in black and grey, and they won’t corrode, rust, or conduct electricity.
We are a nylon cable gland manufacturer and global supplier based in Yueqing, Zhejiang, China — supplying distributors, wholesalers, and OEM partners across 50+ countries directly from our factory. Whether you need standard PG, metric, or NPT thread sizes, or a customised nylon cable gland to your specification — we’ll supply it with the certifications and documentation your procurement team needs.
What is a Nylon Cable Gland?
A nylon cable gland — also called a plastic cable gland or nylon PA66 cable gland — is a cable entry fitting made from polyamide 66 (PA66), a high-performance engineering plastic. Unlike brass glands, nylon glands are non-conductive, corrosion-proof, and significantly lighter — making them the preferred choice for solar PV installations, outdoor enclosures, plastic junction boxes, and anywhere you need a lightweight, weatherproof cable entry without the cost of metal. They incorporate the same internal EPDM or NBR compression seal as brass glands and achieve the same IP68 rating under IEC 60529.

How to Choose the Right Nylon Cable Gland
Five things to confirm before you order — getting these right means the right gland first time.
Confirm nylon is the right material
Nylon is ideal for plastic enclosures, solar installations, and applications where weight, cost, or non-conductivity matters. If you’re in salt spray, extreme heat, or a mechanically aggressive environment — brass or stainless steel may be the better choice.
Choose your IP rating
Our standard nylon cable glands are IP68 as a minimum — suitable for outdoor, wet, and submerged applications. If you only need IP65 for a dry indoor enclosure, our elbow and multi-hole variants cover that range.
Confirm your thread standard
PG for Europe and Asia, metric for global ISO installations, NPT for the US and Canada, MG for Asian industrial equipment. Match the thread to your enclosure — not the cable.
Match cable OD to the entry range
Your cable’s outer diameter must fall within the gland’s stated entry range. Use our size chart above — or send us your cable spec and we’ll confirm the correct size.
Choose the right variant
Standard for most outdoor and weatherproof applications. Strain relief for flexible cables under load. Elbow for tight cable routing. Multi-hole for high cable density. Ex e for hazardous area Zone 1/2.
Where Our Nylon Cable Glands Are Used
Here are the most common applications we supply into — and what we’d typically recommend for each.
01
Solar PV & Renewables
UV-stabilised nylon IP68 in M20 or PG16 — our most popular spec for solar installers and EPC contractors. Handles UV exposure, thermal cycling, and rain without degrading.
02
Outdoor Enclosures
IP68 nylon for junction boxes, distribution boards, and utility enclosures installed outdoors. Non-conductive body eliminates earthing concerns in plastic enclosure installations.
03
Telecoms & Data

04
Industrial Automation
Strain relief nylon glands for flexible cable entries on PLCs, sensor wiring, and control panels. Non-conductive body prevents interference with signal cables.
05
Building & Construction
IP65/IP66 nylon for external lighting, façade wiring, and plant room enclosures. Available in bulk with mixed sizes on a single order.
06
OEM Equipment
Custom nylon cable glands — specific colours, non-standard sizes, private label packaging — for OEM manufacturers who specify our glands into their equipment builds. Consistent quality batch to batch, factory-direct.

Questions We Get Asked About Nylon Cable Glands
Common questions from distributors, OEM buyers, and electrical engineers sourcing cable glands from Difvan.
What is the difference between nylon and brass cable glands?
Nylon PA66 glands are lighter, non-conductive, and corrosion-proof — making them better suited to plastic enclosures, solar PV, and outdoor applications where weight and cost matter. Brass glands offer greater mechanical strength, natural EMC conductivity, and better performance in extreme heat or aggressive mechanical environments. Both achieve IP68 — the choice comes down to your environment, not the protection level.
Are nylon cable glands suitable for outdoor use?
Yes — our nylon cable glands are made from UV-stabilised PA66 polyamide, which means they won’t degrade, discolour, or lose mechanical strength under prolonged UV exposure. They’re rated IP68 and flame-retardant to UL94 V-2. They’re used extensively in solar PV installations, outdoor street furniture, and external lighting enclosures across 50+ countries.
What PA66 material grade do you use for your nylon cable glands?
Yes — we regularly supply bulk nylon cable gland orders in standard black and grey, and can produce custom colours for OEM manufacturers who need colour-coded cable management systems or brand-matched components. Custom colour orders are subject to minimum quantities — contact us for MOQ and pricing.
What PA66 material grade do you use for your nylon cable glands?
We use polyamide 66 (PA66) — a higher-grade engineering plastic than PA6, with better heat resistance, dimensional stability, and chemical resistance. Our PA66 compound is UV-stabilised for outdoor use and flame-retardant to UL94 V-2. RoHS-compliant — free from restricted substances.
How do I make sure quality stays consistent across bulk orders and phased project deliveries?
This is the right question to ask any supplier before committing to volume. At Difvan, every production batch goes through in-process inspection and is tested to IEC 60529 before dispatch — and we maintain batch traceability records for every order. For large or phased bulk supply arrangements, we can provide random sampling reports and certificates of conformity per batch. If your project spans multiple deliveries over months, we’ll hold agreed stock at our factory and release to your schedule — so quality and specification stay consistent from first delivery to last.
Can I order nylon cable glands in different colours for a colour-coded installation system?
Yes — and it’s a more common request than you might think. Standard colours are black and grey, which we keep in stock across all sizes. For bulk OEM orders, we can produce nylon cable glands in custom colours — red, blue, yellow, and others — for colour-coded cable management systems that make maintenance and identification faster in the field. Custom colour orders require a minimum quantity, which we’ll confirm at the quotation stage. If you’re specifying a colour-coded system across a large installation, send us your colour requirements and quantities and we’ll advise on the most cost-effective approach.
Do nylon cable glands come with the locknut, washer, and sealing insert included, or do we need to order these separately?
All Difvan nylon cable glands are supplied as a complete assembly — lock nut, washer, gland body, claw, seal, and sealing nut all included in the pack. Nothing needs to be ordered separately for a standard installation. For bulk orders, pack quantities vary by size — for example, PG7 comes 20 pieces per pack, PG16 comes 4 pieces per pack. If you need loose components — additional sealing inserts or locknuts as spares — we can supply those separately. Just specify when you enquire.

Patch Panel vs Switch: What Is the Difference & Do You Need Both?
October 5, 2026 No Comments
If you’re comparing a patch panel vs switch, the main difference is straightforward. Your patch panel is a passive component that terminates and organizes network cabling. Your network switch is an active device that requires power and forwards data between connected devices. In a structured network, you commonly use both because they perform different functions.
