What are Die-Cut Gaskets and Seals?
Die-cut gaskets and seals are custom-converted components commonly made from thin, flexible materials, including cork, sponge rubber, EDPM foam, neoprene, aramid fibers (Nomex®), vulcanized fish paper, graphite, adhesive-backed foams, and more. Custom-cut gaskets and seals serve several functions within assemblies, like:
- Sealing out moisture, dust, chemicals, and other contaminants
- Filling gaps and unwanted spaces
- Preventing air. fluids, or gases from leaking or escaping
The benefit of die-cut gaskets and seals is that they can be custom-cut to fit irregular geometries and tight spaces or paired with a pressure-sensitive adhesive backing to ensure optimal fit and performance across different surfaces.
Turning raw material into functional gaskets and seals: The Role of a Skilled Converting Partner
A skilled converting partner essentially acts as the bridge between raw material and a functional assembly-ready component, enabling them to be easily integrated into complex assemblies.
A vertically integrated converting partner like JBC adds value through:

Yes, adhesive-backed gaskets are extremely common and allow you to securely fasten components to a wide range of surfaces.
As a vertically integrated converter, JBC Technologies is capable of laminating an adhesive to the back of gaskets & seals during the die-cutting process. We also leverage our extensive supplier network to source certain gasket materials that come with adhesive pre-applied.
Yes, besides sealing out contaminants and filling gaps, die-cut gaskets and seals can help prevent unwanted noise, vibration, and even manage extreme temperatures, depending on which specific material is selected.
Consult with your converter partner to determine whether the gasket material you've selected solves the challenges you're trying to address.
Yes, JBC provides gaskets & seals on rolls, sheets, or as individual components. For rolls and sheets, JBC can kiss-cut through just the gasket material, leaving the liner intact for optimized part presentation and delivery.
Yes, JBC transforms raw materials into custom-shaped gaskets based on customer-supplied designs. Do you need a custom-shaped gasket? Send us your design!
JBC Technologies prioritizes upfront engineering collaboration during the quoting and R&D process to ensure each gasket design features optimized nesting and minimal material scrap. We compare yield expectations with actual first-run production and negotiate material MOQs with suppliers to help align with your required volumes and reduce waste, scrap, and overall costs.
