- Connector-matched plug
- Outdoor electrical protection
- Material for outdoor service

Product overview
Understand the Product Before Selecting a Specification
ouning supplies rubber sealing plugs for E-Bike connectors, wire harnesses, and electrical interfaces. The plug is used to protect a connector or unused interface from water and dust, subject to the housing design. Size and material should be confirmed against the connector drawing and exposure conditions.
Connector-matched plug
The plug follows the connector shell or interface rather than a generic cap size.
Outdoor electrical protection
Water, dust, and temperature around the bicycle should be stated. Protection still depends on the complete connector assembly.
Material for outdoor service
Silicone and EPDM are commonly reviewed. Hardness and geometry must also retain the plug in the housing.

Questions & answers
E-Bike Plug Questions
Common questions about selecting and requesting E-Bike Plug.
Can you match an existing E-Bike connector plug?
Yes. Send a sample or drawing of the connector interface together with quantity and color.
Does the plug guarantee a waterproof rating by itself?
No. Water protection depends on the connector, compression, and test method. Share any required assembly test with the inquiry.
Which material is typical?
Silicone and EPDM are commonly reviewed for outdoor electrical plugs. Share temperature and exposure for a practical choice.
