Silicone gaskets for glass jars should fit the particular lid interface without being pinched against an exposed glass edge. The gasket seat and closure movement determine whether the flexible ring remains correctly positioned as the lid is applied.
ETOL supports custom dimensions, colors and material selections. Choose the formulation for the contents and intended cleaning process. Compare the actual contact path and available compression space rather than assuming similar glass lids use the same ring.
Inspect the glass and rubber for damage before fitting. Place the gasket without tension and apply the lid by its intended method, checking that no section has shifted toward the opening. Evaluate the completed closure for the required function. During cleaning, include the hidden gasket face and its seat. Keep sharp tools away from both the seal and glass. Replace a torn or permanently distorted component after checking the mating surfaces, instead of using an extra gasket layer to cover a damaged edge or uncertain fit.

Identify key dimensions, mating surfaces and quantity
Agree the compound and manufacturing approach
Review the fit and agreed requirements in the assembly
Manufacture and check against the approved requirements
Identify temperature, contact fluids and repeated movement.
Consider hardness together with wall thickness and support.
Check access, mating dimensions and the fitting sequence.
Yes. Show the receiving opening, contact surfaces and clearance limits. We can review the dimensions and retaining features around the intended fit.
Agree the critical dimensions, material, hardness, visible surfaces and sample requirements. Explain how the part is installed and which interfaces control its function.
A sample can help explain the structure. Compare it with the assembly because wear, swelling or compression may have changed its original dimensions.
The material, part geometry, tooling, quantity and finishing affect the quotation. Include the intended batch size and delivery destination when describing your requirements.
