GBT Charging Port Cover — China Standard Dust Cap

A snap-fit dust cover for the GBT (GB/T 20234) charging interface used on China-market EVs — keeping the socket clean and dry between charges.

Built to the China-Market Interface

GBT is the charging interface standard for vehicles sold in China, with distinct AC and DC connector shapes. Our GBT cover is engineered to that interface geometry — a snug snap-fit that stays on at speed, with the same IP54/IP67 weather protection and OEM customization as the rest of the range.

GBT Cover Questions

Is the GBT cover the same as a Type 2 cover?+

No — GBT (GB/T 20234) is a different interface from Type 2 (IEC 62196-2), with its own AC and DC connector shapes. The cover must match the GBT geometry to seal properly.

Can you ship samples for fit testing?+

Yes — send us your port photo or reference part, we confirm the version and ship first-article samples for your fit test. Sample quantities for evaluation start from a small number of units.

Do you make GBT covers for export brands?+

Yes — GBT covers are commonly sourced by brands selling into China or exporting China-made EVs. OEM branding, packaging and bulk programs are standard.
