Our Solutions
Gaskets & Seals
Our top-quality gasket materials provide excellent resistance to compression set, high resiliency, and shock absorption. PNA’s gaskets prevent leakage, while maintaining their integrity regardless of the environment.PNA offers a wide variety of rubber grades to produce custom-fabricated gaskets. Most rubber grades are available as thin as .016″ thick up to .250″ thick. Additionally, rubber grades are produced as soft as 30 durometer and as hard as 90 durometer.

Custom gaskets that seal, and
hold their integrity.
Top-quality gasket materials with excellent resistance to compression set, high resiliency, and shock absorption. PNA gaskets prevent leakage while holding their integrity regardless of environment — converted from a wide range of rubber grades on our Zünd digital floor, prototype through production.

Seals that keep
their integrity.
PNA’s gasket materials pair excellent resistance to compression set with high resiliency and shock absorption. They prevent leakage and hold their shape regardless of the environment they operate in.
A gasket only works if it recovers — sealing pressure that fades over time is a leak waiting to happen.
PNA offers a wide variety of rubber grades for custom-fabricated gaskets. Most grades are available as thin as .016″ up to .250″ thick, and produced as soft as 30 durometer and as hard as 90 durometer — matched to the clamp load and interface your design specifies.
For demanding environments, gaskets fabricated with silicone foam rubber stay highly resilient with low compression set, span a wide operating range of −67 °F (−55 °C) to 392 °F (200 °C), and resist UV and ozone.
01
Low compression set
Gasket grades spring back after load, holding a leak-tight interface through repeated assembly, thermal cycling, and long service life.
02
High resiliency & shock absorption
Resilient compounds absorb vibration and shock, protecting mating surfaces and sensitive hardware in rugged and mobile installations.
03
Leak-tight in any environment
The seal blocks moisture, dust, air, and pressure differentials — maintaining integrity across temperature, weather, UV, and ozone exposure.
04
Converted to your dimensions
Die-free Zünd cutting converts sheet, foam, and sponge stock to exact print geometry — no tooling cost, rapid revisions, tight nesting for yield.
The right rubber
for the seal.
Selecting the correct grade is critical to sealing reliability. We convert gaskets across the full rubber range — the compound your application specifies is the compound we cut.
Silicone Rubber
Outstanding temperature range with excellent UV, ozone, and weather resistance — flexible from deep cold to high heat, with strong compression-set recovery.
Silicone Foam / Sponge
Highly resilient closed-cell foam with low compression set — a wide operating range and excellent UV / ozone resistance for cushioning environmental seals.
Ethylene Propylene Diene Monomer
Excellent resistance to weathering, ozone, UV, steam, and polar fluids with good flexibility and aging characteristics — the go-to outdoor sealing grade.
Chloroprene Rubber
Balanced general-purpose grade — good weather, ozone, and moderate oil resistance with strong mechanical properties and flame retardance.
Fluorocarbon
Excellent chemical, fuel, and oil resistance with strong high-temperature performance and good compression-set resistance for aggressive service.
Nitrile Butadiene Rubber
Cost-effective grade with excellent oil, fuel, and hydrocarbon resistance plus strong mechanical and abrasion properties for sealed mechanical joints.
Material comparison — at a glance
Values are representative and vary with compound, cure, and application. Foam and sponge grades add cushioning and NVH control to the seal; specialty grades extend temperature and chemical range further. Send your service conditions — we’ll confirm the grade against temperature, media, and pressure.
Every gasket form,
