Car diffuser wooden caps are part of a hanging fragrance system that includes the glass bottle, sealing component and cord. The wooden cap may be used as the scent-release surface after controlled wetting, while a separate inner plug or seal may be required to reduce leakage during filling and shipping.Confirm cap-to-neck fit, cord assembly, hanging balance and fragrance absorption with the exact bottle and formula. Test the filled unit under movement, tilt and elevated temperatures relevant to vehicle use before approving bulk production.

Share your bottle or jar model, opening, neck finish and functional requirements. We can shortlist compatible lids, pumps, caps, plugs or accessories.
Decorative and functional cap matched to the neck of the selected car diffuser bottle.
Cord length and assembly selected for secure hanging and balanced presentation.
A separate sealing component may be used to control leakage before the wooden cap is wetted.
Confirm bottle opening, wooden-cap fit, cord hole or attachment structure and any separate inner plug on the exact bottle.
Test cap absorption, controlled inversion, cord retention, leakage, evaporation, movement and elevated-temperature behavior with the actual fragrance.

Still have a question? Ask our team →Check the glass bottle, sealing component, wooden cap and hanging cord as one system. Confirm usable fill, cap fit and absorption, cord strength and finished hanging length, then test the assembled product for leakage while tilted, moved and exposed to temperatures relevant to vehicle use.
If the wooden cap is wetted by briefly inverting the bottle, define a controlled procedure and verify that fragrance is absorbed without uncontrolled liquid release. Consumer instructions and protective retail packaging should support the same use method approved during testing.
Provide the exact container model whenever possible. If a model is not available, measure the finished opening or neck and include the dimensions that control component fit: outside and inside diameter, thread or crimp specification, rim or lid-seat geometry, relevant heights and any insertion depth.
For pumps, also provide the neck finish and required dip-tube length. For lids and stoppers, a technical drawing or physical sample is strongly preferred because nominal diameter alone does not describe threads, tapers, gaskets, inserts or fit tolerances.
Separate accessory orders may be possible, but compatibility must be confirmed before production. Provide the Bright Glassware model number or the exact bottle or jar opening/neck dimensions, required material and finish, quantity and, when possible, a drawing or physical sample.
Do not assume an accessory will fit only because the nominal diameter looks similar. Opening geometry, thread or insertion details, tolerances and component construction should be checked on representative samples.
In many projects, component colors and finishes can be coordinated with the bottle or jar design. The available route depends on the component material and may involve painted, plated, anodized, printed, molded-color or natural-material finishes.
Approve physical color and finish samples under consistent lighting. Metallic and natural materials can appear different from a Pantone chip or screen rendering, so the assembled bottle, jar or closure set should be the final visual reference.
