Long-Thread Waterproof Cable Gland
GNWTF
Product Overview
Long-Thread Waterproof Cable Gland
Standard cable glands can work loose over time in high-dynamic environments due to insufficient thread engagement. GNWTF's extended thread design deepens the engagement and expands the sealing contact surface — maintaining a secure, airtight hold even under frequent cable movement or continuous equipment vibration.
Made from UL-certified halogen-free PA66 nylon (UL94V-2) with EPDM seal, IP68 rated. Static operating temperature -40°C to 100°C (peak 120°C); dynamic -20°C to 80°C (peak 100°C). UL94V-0 upgrade and custom EPDM formulas available for demanding applications.
Key Features
- Extended thread for deeper engagement: Greater engagement depth than standard type — secure hold under high-dynamic and vibration environments
- Expanded sealing contact area: Larger sealing surface maintains IP68 waterproofing performance more reliably over time
- Customizable EPDM seal: Cold-resistant, high-temp, acid/alkali-resistant, and anti-corrosion formulas available on request

Application Scenarios
Mobile Automation Equipment
Robotic arms, AGVs, and other mobile platforms subject cables to constant movement and tension. Extended thread engagement prevents loosening and maintains sealing integrity over the equipment's service life.
Machinery / High-Vibration Environments
Extended threads increase contact surface area with the equipment housing wall, maintaining reliable waterproof sealing even under sustained industrial vibration.
Outdoor / Demanding Chemical Environments
IP68 protection paired with custom EPDM seal formulas — suited for outdoor control systems, chemical plant environments, and applications requiring long-term waterproofing and chemical resistance.
Frequently Asked Questions
Q1｜What is the difference between a long-thread and a standard cable gland? When do I need the long-thread type?
Standard cable glands have a thread length suited for static wiring applications. GNWTF's extended thread provides deeper engagement and a larger sealing contact surface — ideal when cables are subject to frequent movement, equipment operates under sustained vibration, or housing walls are thick enough that a standard thread cannot engage fully.
Q2｜Is GNWTF's IP68 waterproofing guaranteed in high-dynamic applications?
IP68 testing is conducted under static conditions. In dynamic applications (cable movement, vibration), the extended thread's deeper engagement reduces the risk of seal displacement caused by vibration. Dynamic operating temperature is -20°C to 80°C. For extreme dynamic requirements, contact our sales team for an application assessment.
Q3｜What EPDM custom seal formulas are available? How do I choose the right one?
Standard EPDM provides good weathering and ozone resistance. Custom options include: cold-resistant (cold storage/low-temperature environments), high-temp (engine compartments or high-heat equipment), acid/alkali-resistant (chemical plants, semiconductor equipment), and anti-corrosion (marine salt-spray environments). Describe your operating conditions to our sales team for the best recommendation.
Q4｜Can GNWTF's material be upgraded to a higher flame retardancy grade?
Yes. Standard material is UL94V-2 (self-extinguishing flame retardant). A UL94V-0 upgrade is available for applications requiring faster self-extinguishing performance and no burning drip — suitable for power equipment or medical devices with strict fire safety requirements.
Q5｜How do I confirm the correct thread specification and cable clamping range?
Two parameters must be confirmed: ① the thread form and size of the equipment housing entry hole (e.g., M20, M25 metric); ② the cable outer diameter (OD) falls within the gland's clamping range. Cross-reference the cable entry diameter (d) column in the engineering drawing on this page. Contact sales with your equipment details if you need selection assistance.
