Custom Die-Cut Gaskets for Equipment
Sealed joints, die-cut to your print
Custom die-cut gaskets converted from elastomers, foams, and adhesive-backed constructions to match the joint, both mating surfaces, and the service conditions. First-article inspection, PPAP documentation, material traceability, and certificates of conformance are available.
About custom gaskets
We have decades of experience fabricating custom gaskets for demanding industrial applications. Our die-cutting and digital cutting equipment produces gaskets in virtually any shape, size, or material configuration — from simple flat gaskets to complex multi-layer assemblies.
Most customers come to us for gaskets because we are already making their nameplates and overlays. The same converting equipment that cuts a graphic overlay cuts a gasket, and putting both on one purchase order removes a supplier rather than adding one.

Elastomers
We stock and convert a broad selection of gasket materials to meet the mechanical, thermal, and chemical resistance demands of your application.
EPDM
Excellent weather, ozone, and UV resistance. −40°F to +250°F, durometer 40–80 Shore A. The default for outdoor and weather sealing.
Neoprene (CR)
Good oil and flame resistance. −40°F to +220°F, durometer 40–80 Shore A.
Silicone
Wide temperature range from −65°F to +450°F, durometer 20–80 Shore A. FDA-compliant grades available.
Nitrile (Buna-N)
Superior oil and fuel resistance. −30°F to +250°F. The usual choice around fuel systems and hydraulics.
Viton® (FKM)
Outstanding chemical and high-temperature resistance up to +400°F.
Natural rubber
High tensile strength and elasticity, with good abrasion resistance.
Foams and non-metallic materials
Poron® foam
Microcellular urethane for cushioning, sealing, and vibration dampening. Recovers more than 90% after compression, which is what keeps a seal working through repeated access.
Neoprene sponge
Closed-cell foam for weather sealing and insulation.
Cork
Natural compressibility, with oil-resistant composite grades available.
Cork-rubber composites
Combines cork compressibility with rubber resilience.
Compressed non-asbestos fiber
CNA gasket sheets for flange sealing.
Felt
Wool and synthetic felt for wicking, filtering, and cushioning.
PTFE (Teflon®)
Chemically inert, and the answer for corrosive media.
Cutting processes
We use 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 and CNC routing
Knife and router cutting on flatbed plotters for prototypes, short runs, and complex geometries. No tooling charges, and fast turnaround for design iterations.
Kiss cutting
Cuts through the gasket material only, leaving the adhesive liner intact for easy peel-and-stick installation on your line.
Because digital cutting carries no tooling charge, a first article can be in your hands without waiting on a die. See die and digital cutting.
Tolerances and specifications
Standard tolerances
±0.010″ for die-cut parts, ±0.005″ for digitally cut parts.
Material thickness
0.005″ to 1.000″.
Maximum sheet size
60″ x 40″ die cutting, 72″ x 48″ digital cutting.
Adhesive-backed options
3M™ pressure-sensitive adhesives including VHB™, 467MP, 468MP, and 9472LE.
Documentation
First-article inspection and PPAP documentation available, with full material traceability and certificates of conformance.
Packaging
Custom packaging and kitting for line-side delivery.
Applications
Our custom gaskets serve a wide range of industries.
-
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
-
Aerospace and defense — MIL-SPEC gaskets for avionics bays, hatches, and environmental sealing
-
Food and beverage — FDA and USDA-approved materials for processing equipment
How a gasket order runs
- 1
Send the drawing and describe the joint. The real joint matters more than the outline — openings, exclusions, compression, and assembly conditions. Quotes are free on every order.
- 2
We recommend the material. Chosen against temperature range, media, compression set, and whether the joint is opened for service.
- 3
Prototype or first article. Digital cutting produces samples with no tooling charge, so the fit is proven before a die is made.
- 4
Production. Die cut for volume or digitally cut for shorter runs, in an ISO 9001:2015 certified facility. Rush work runs 3–5 business days for an additional fee.
- 5
Delivery. Orders ship within a 10% over/under quantity standard, with custom packaging and line-side kitting available.
Gasket RFQ checklist
-
A drawing with the outline, all openings, and any exclusion areas
-
Material, or the temperature range, media, and chemicals it must resist
-
Thickness, and the compression the joint applies
-
Whether the gasket needs an adhesive backing, and which face
-
Tolerance requirements, and whether PPAP or first-article documentation is needed
-
Quantity, and whether this is a prototype, a first run, or a repeat program

Why U.S. Nameplate Co.
Why OEMs source gaskets from U.S. Nameplate Co.
One partner, one roof
Metal identification and flexible labels are produced under one roof in Mount Vernon, Iowa, so a single supplier covers plates, tags, overlays, decals, and safety labels instead of three.
No tooling fee on in-house equipment
U.S. Nameplate Co. does not charge a tooling fee for any in-house equipment. A one-time charge applies only when a tool has to be created for your order.
You reach a person
Customer service representatives are available 8:00 AM–4:30 PM CST Monday through Thursday and 7:00 AM–3:30 PM CST Friday. You will always reach someone in person.
Built to outlast the equipment
Metal nameplates are built to withstand up to 25 years of outdoor exposure, with some products guaranteed for 25 years or more. Safety labels are UL authorized and OSHA compliant, produced in an ISO 9001:2015 certified facility.
