Material selection
Select solid silicone for durable compression sealing and silicone sponge for low-clamp-force gap filling.
DRAWING-BASED CUSTOM PARTS
Custom Die-Cut Silicone Gaskets
Flexible silicone gasket profiles cut to your drawing for stable sealing across hot, cold and weather-exposed assemblies.
Custom solid-silicone gaskets with precise apertures, bolt patterns and thicknesses for resilient environmental sealing.
Engineered Custom Die-Cut Silicone Gaskets
Die-cut silicone gaskets provide a clean, repeatable seal around covers, flanges and access panels. The material remains flexible across a wide temperature range and can be supplied in food-contact, flame-retardant or electrically insulating grades where required.
Material approach
Silicone retains elasticity in temperature extremes and resists ozone and outdoor weathering better than many general-purpose rubbers.
Key features
- Broad temperature performance
- UV and ozone resistance
- precise die-cut geometry
- low odour
- optional food-grade and flame-retardant compounds.

Engineering Guide
Practical points to include when selecting foam and preparing a drawing for review.
Geometry and thickness
Provide sufficient sealing land and use compression stops when clamp load can vary widely.
Assembly performance
Target controlled gasket compression; exact percentage depends on compound hardness, joint tolerance and ingress target.
Production route
Specify compression, flange flatness and bolt spacing so the gasket is not over-compressed or extruded.
Applications / Where It Fits

Frequently Asked Questions
Can silicone gaskets be used outdoors?
Yes. Silicone has strong resistance to UV, ozone and weathering when the compound suits the application.
What hardness should I select?
Softer grades seal uneven flanges at lower clamp force; firmer grades better resist extrusion and permanent deformation.
Can a silicone gasket carry adhesive for assembly?
Yes. A pressure-sensitive adhesive can be applied for placement retention before the joint is clamped.
Are food-grade silicone options available?
Food-contact grades can be selected when the application and required compliance are identified.
What should a drawing include for custom die-cut silicone gaskets?
Include sealing land, bolt pattern, flange condition, target compression and material hardness.
Can custom die-cut silicone gaskets be supplied for production assembly?
Yes. Specify compression, flange flatness and bolt spacing so the gasket is not over-compressed or extruded. Delivery format, liner configuration and packaging are specified for the assembly workflow.
How is the right custom die-cut silicone gaskets construction selected?
Select solid silicone for durable compression sealing and silicone sponge for low-clamp-force gap filling. The drawing and operating conditions establish the final construction.
