Hex Socket Blanking Plug (Sealing Cap)
GQNEFSP
Product Overview
Hex Socket Blanking Plug (Sealing Cap)
Every unused threaded port in an equipment housing is a direct pathway for dust and moisture — and leaves your IP rating exposed. GQNEFSP's hex socket drive lets you torque it down with a standard hex key for an immediate IP68-sealed closure, ensuring no gaps remain in your enclosure's protection.
Industrial-grade nylon body rated for -40°C to 100°C. Standard black and grey in stock; custom colors available on request. Suitable for electrical equipment, distribution panels, and industrial mechanical housings.
Key Features
- IP68 full enclosure protection: Torque-tighten to achieve complete dustproof and waterproof seal — no IP rating gap from any unused port
- Hex socket anti-loosening design: Hex key tightening delivers uniform clamping force that resists vibration-induced loosening
- Nylon weather and chemical resistance: No corrosion, rust-proof — suitable for humid or mild chemical contact environments

Application Scenarios
Electrical Equipment / Distribution Panels
Seals spare threaded ports to prevent dust and moisture ingress, maintaining the enclosure's full IP rating without compromise from any unsealed opening.
Industrial Mechanical Housings
Used alongside cable glands and corrugated tubing fittings to seal all unoccupied cable ports, ensuring complete enclosure protection integrity.
Outdoor / Wet Environment Equipment
IP68 rated for sustained submersion — suitable for outdoor power installations, marine instrument enclosures, and equipment in harsh, continuously wet environments.
Frequently Asked Questions
Q1｜Why must equipment threaded ports be sealed with a blanking plug? What happens if left open?
An enclosure's IP rating is measured with all ports fully sealed. Any open port immediately drops the device's actual protection to zero — regardless of how well every other port is sealed. In dusty or wet industrial or outdoor environments, an unsealed threaded port is the most direct ingress path for moisture and particulates.
Q2｜What does GQNEFSP's IP68 rating mean? How does it differ from IP67?
IP68 certifies complete dustproofing (level 6) and capability for sustained submersion (level 8 — typically 1 m+ for 30 min+), exceeding IP67 which only covers brief immersion. GQNEFSP achieves IP68 once properly torqued with a hex key.
Q3｜What is the advantage of hex socket design over flat-head (slotted) plugs?
A hex socket requires a hex key to tighten, delivering greater and more uniform clamping force than slotted designs. This resists vibration-induced loosening and prevents unauthorized hand-removal — making it appropriate for permanent, field-installed sealing applications.
Q4｜Which thread specifications does GQNEFSP support? How do I confirm the correct size?
Confirm the thread form (Metric / G-PF) and size (e.g., M16, M20, G1/2) of your enclosure port. Cross-reference the specification table or engineering drawing on this page to ensure a full match — any mismatch will prevent achieving IP68 sealing. Contact our sales team if you need sizing assistance.
Q5｜Can GQNEFSP be used alongside Good Gi cable glands in the same enclosure?
Yes. GQNEFSP blanking plugs and Good Gi cable glands share the same thread specifications, allowing a single enclosure to use cable glands (occupied ports) and blanking plugs (unoccupied ports) simultaneously — ensuring consistent IP protection across the entire enclosure with streamlined procurement.
