ISO 9001 certified for consistent quality on every order.
Contact UsCustom Die-Cut Gaskets & Seals
U.S. Nameplate Co. has decades of experience fabricating custom gaskets for demanding industrial applications. Our state-of-the-art die-cutting and digital cutting equipment allows us to produce gaskets in virtually any shape, size, or material configuration. From simple flat gaskets to complex multi-layer assemblies, we deliver precision-cut parts that meet your sealing requirements and withstand the toughest operating environments.
Materials
We stock and convert a broad selection of gasket materials to meet the mechanical, thermal, and chemical resistance demands of your application:
Elastomers
- EPDM – Excellent weather, ozone, and UV resistance; temperature range -40°F to +250°F; durometer 40–80 Shore A
- Neoprene (CR) – Good oil and flame resistance; temperature range -40°F to +220°F; durometer 40–80 Shore A
- Silicone – Wide temperature range -65°F to +450°F; FDA-compliant grades available; durometer 20–80 Shore A
- Nitrile (Buna-N) – Superior oil and fuel resistance; temperature range -30°F to +250°F
- Viton® (FKM) – Outstanding chemical and high-temperature resistance up to +400°F
- Natural Rubber – High tensile strength and elasticity; good abrasion resistance
Foams & Non-Metallic Materials
- Poron® Foam – Microcellular urethane for cushioning, sealing, and vibration dampening; recovers >90% after compression
- Neoprene Sponge – Closed-cell foam for weather sealing and insulation
- Cork – Natural compressibility; oil-resistant composite grades available
- Cork-Rubber Composites – Combines cork compressibility with rubber resilience
- Fiber (Compressed Non-Asbestos) – CNA gasket sheets for flange sealing
- Felt – Wool and synthetic felt for wicking, filtering, and cushioning
- PTFE (Teflon®) – Chemically inert; excellent for corrosive media
Cutting Processes
U.S. Nameplate Co. uses precision cutting methods to produce gaskets with tight tolerances and clean edges:
- Die Cutting – Steel rule dies and clicker presses for high-volume production runs. Ideal for repeatable parts requiring consistent dimensions across thousands of pieces.
- Digital Cutting / CNC Routing – Knife and router cutting on flatbed plotters for prototypes, short runs, and complex geometries. No tooling charges; fast turnaround for design iterations.
- Kiss Cutting – Cuts through the gasket material only, leaving the adhesive liner intact for easy peel-and-stick installation.
- Waterjet Cutting – For thicker materials and applications requiring no heat-affected zone.
Applications
Our custom gaskets serve a wide range of industries and applications:
- HVAC – Duct sealing, compressor gaskets, and vibration isolation pads
- Electronics Enclosures – EMI/RFI shielding gaskets, dust seals, and environmental protection for NEMA-rated enclosures
- Industrial Equipment – Flange gaskets, pump seals, and access panel gaskets for heavy machinery
- Automotive – Under-hood seals, battery compartment gaskets, and vibration dampeners
- Medical Devices – FDA-compliant silicone gaskets for diagnostic equipment and fluid handling systems
- Aerospace & Defense – MIL-SPEC gaskets for avionics bays, hatches, and environmental sealing
- Food & Beverage – FDA and USDA-approved materials for processing equipment
