Silicone stopper manufacturer
Defining a custom silicone stopper
A silicone stopper manufacturer needs a clear description of the finished component before a custom profile can be evaluated. Begin with a section drawing that shows the body, seating face and any gripping feature. Identify which surfaces contact the vessel and which remain exposed after installation. This separates dimensions that control the closure fit from features chosen mainly for handling or appearance.
Specify the details that distinguish the part
Include the overall height, taper or straight-wall dimensions, and the position of any through-holes. For more than one passage, show their spacing as well as their individual diameters. Mark the dimensions that require controlled tolerances in the assembly. If color is used to identify a size or application, include the chosen Pantone reference and explain how different versions will be distinguished during use.
Connect material choice to the application
Describe the medium at the closure, the operating temperature and the cleaning or reuse cycle. These conditions guide the silicone compound selection and the evaluation of a proposed sample. For a stopper that will be inserted repeatedly, assess the handling sequence and the condition of the contact edge after use. Avoid replacing application requirements with broad promises about durability; the finished part must be judged in the assembly it was designed for.
Agree on a production reference
Before repeat manufacture, establish the accepted drawing revision and the features to check on the finished stopper. Keep the approved color, material designation and fit observations together with that revision. If a passage, grip or body dimension changes later, treat it as an explicit part change. A clear reference helps the manufacturer and buyer discuss the same component from sampling through subsequent orders.
Stopper & Plug Size Catalog
Compare four stopper profiles and check the selected part dimensions against your opening and available depth. Each profile has its own drawing and dimension meanings.
Custom colors are available to your Pantone color code. Include the code in your inquiry.
RST T-Shaped Plugs
Match stem diameter A, flange diameter B, stem length C and flange thickness D. E refers to the underside recess; use the selected row and approved drawing to confirm the actual profile.
RSA Tapered Corks
Compare large-end diameter A, small-end diameter B and Height, in mm. The mating bore and required seating depth determine where the taper contacts the opening.
RSB Undercut Plugs
Compare neck diameter A, flange diameter B, flange-to-lip distance C and flange thickness D. Check panel thickness and rear clearance. E refers to the underside recess.
RSD T-Shaped Stoppers
Compare stem diameter A, flange diameter B, stem length C and head thickness D, in mm. Check the seating surface and available depth as well as the hole diameter.

Discuss Your RequirementsProduct specifications
- Product form
- Custom silicone stopper made to an approved section drawing.
- Functional section
- Identify body height, taper or straight wall, seating face and the exposed gripping feature.
- Passage detail
- Dimension every through-hole, its location and spacing from other passages; mark the assembly-critical tolerances.
- Material and reuse
- Specify the medium, operating temperature and cleaning cycle; evaluate the contact edge after the intended repeated insertion.
- Version identification
- Define the chosen color reference and how similar versions will be identified during use.
- Production control
- Keep the accepted drawing revision, compound and sample-fit observations together; treat later passage, grip or body changes as explicit part revisions.
