Custom Silicone Seals and Gaskets
Flexisil supports custom molded silicone seals and gaskets made around a drawing-defined joint or profile. Share the mating surfaces, free-state dimensions, installed conditions and quantity so the sealing requirements, material expectations and sample checks can be reviewed for the individual assembly.

Custom silicone seals and gaskets: clarify the joint
- Use a profile drawing to show the sealing face, locating features and mating components. Explain whether the part sits in a groove, between faces or around an opening.
- A gasket may sit between mating faces, while a profiled seal can locate around an opening. Show the actual joint and required profile rather than relying on the product name alone.
- Temperature, contact media, compression and movement must be considered for the actual design. Request the relevant material documentation and agreed assembly checks before approval.
Joint and profile
- Provide the profile drawing with units and distinguish free-state dimensions from installed conditions.
- Identify the mating surfaces, joint geometry, assembly method and critical fit dimensions.
- State whether the design is a ring, frame, strip or another molded profile.
Service requirements
- Describe the contact media, expected exposure and operating conditions.
- Provide any specified material grade, hardness scale, color and testing documentation requirements.
- Agree on application-specific sample checks; this page does not establish a pressure, temperature or chemical compatibility rating.
Production acceptance
- Define the visible surfaces, dimensional features and functional checks that will be reviewed.
- Record the approved drawing revision and batch identification requirements.
Buyer questions
Can the material name alone establish sealing performance?
No. Geometry, installation, material specification and service conditions need review together for the intended application.
What should I send with an existing sample?
Send dimensions, intended use, quantity, any known material specification and the aspects that must match. Agree on sample handling before dispatch.
Can you quote a custom silicone gasket from a sample?
A sample can help explain the geometry. Include known dimensions, mating conditions, quantity and required checks, and agree on the specification before tooling or production.
