Can you make custom gaskets to my exact dimensions?

Yes. We cut custom gaskets to the dimensions you specify. Enter your measurements in the online configurator, choose your material (Neoprene, Silicone, EPDM, Buna-N, Cork, or Fiber), and get an instant price. Custom gaskets ship within one business day after the order is placed. Larger orders may require additional time. No minimum order.

Do you cut custom flange gaskets with bolt holes?

Yes. Our Flange Gasket template lets you specify the outer diameter, inner diameter (bore), bolt circle diameter, number of bolt holes, and bolt hole size. We cut custom flange gaskets in Neoprene, Silicone, EPDM, Buna-N (NBR), Cork, and Fiber/Compressed Gasket Paper with instant online pricing.

Can you cut circular disk gaskets and ring gaskets?

Yes. We cut circular disk gaskets (solid discs) and ring gaskets (annular rings with a center bore) up to 32.5 inches in diameter. Neoprene, Silicone, EPDM, Buna-N, and Cork all available.

Do you cut rectangular gaskets and square gaskets?

Yes. We cut flat rectangular gaskets, square gaskets, and rounded-corner rectangular gaskets to your exact dimensions. Available in Neoprene, Silicone, EPDM, Buna-N (NBR), Cork, and Fiber/Compressed Gasket Paper. Maximum part size 32.5 x 32.5 inches.

What elastomer gasket materials do you cut?

We cut custom elastomer flat gaskets in Neoprene (CR), Silicone, Buna-N (NBR), EPDM, Cork, and Fiber/Compressed Gasket Paper. Each material is available in multiple thicknesses.

How do I get an instant price for a custom cut gasket?

Use the configurator on this page. Select your gasket shape, pick a material and thickness, enter your dimensions, and the price updates live - no quote request, no email, no back-and-forth. Add directly to cart.

What gasket shapes can you cut?

We cut over 30 shapes: disk gaskets, ring gaskets, flange gaskets (with bolt holes), exhaust gaskets, rectangular gaskets, rounded-corner rectangles, square gaskets, capsule/slot gaskets, ovals, pentagons, hexagons, octagons, and trapezoids.

Is there a minimum order quantity for custom cut gaskets?

No minimum order. We cut single custom gaskets as readily as bulk orders. Price per piece decreases automatically with quantity in the configurator.

How long does production take?

Most orders are cut and shipped within one business day. Larger orders may take longer.

What is the maximum size gasket you can cut?

The largest part is 32.5″ × 32.5″ in Neoprene, Silicone, EPDM, Buna-N, Cork, and Fiber/Compressed Gasket Paper. The configurator tells you if your part is too large for the selected material. Contact us for larger parts.

What file format do I need to submit for a custom gasket order?

No file is needed for the standard gasket shapes. Our online configurator generates the cut geometry from the dimensions you enter. A DXF file is only needed if you want a custom outline that is not one of the standard shapes: choose the Custom DXF Upload option and upload a .dxf file.

Excellent resistance to	Fuels, oils, acids, and a very broad range of aggressive chemicals
Poor resistance to	Ketones, low-temperature flexibility, and steam/hot water
Thicknesses available	1/16", 1/8", 3/16", 1/4"

Additional specifications and specific durometers are available on request — contact us with your requirements.

Common Viton Gasket Applications

Aggressive chemical process seals
Fuel-system and aerospace gaskets
High-temperature oil and solvent service
Pump, valve, and manifold seals
Semiconductor and industrial equipment
Automotive fuel and emissions systems

Viton vs Buna-N vs PTFE vs Silicone

Viton — broader chemical and heat range than Buna-N; a premium material that costs more
Buna-N — economical oil and fuel sealing at lower temperatures
PTFE — near-universal chemical resistance, but rigid rather than elastic
Silicone — high heat, but not for oils or fuels

See the materials guide for the full comparison.

When to Choose Viton

Choose Viton when you need both chemical resistance and high-temperature performance in one gasket — it outperforms Buna-N on heat and chemical breadth. It costs more than standard elastomers, so reserve it for demanding chemical or high-heat service.

Limits to know

Viton is weak against ketones, steam and hot water, and low-temperature flexibility. For oil sealing at lower temperatures, Buna-N is the more economical choice.

Viton Gasket FAQs

What is Viton gasket material?

Viton is a fluoroelastomer (FKM) with outstanding resistance to fuels, oils, acids, and aggressive chemicals at high temperatures — a premium material for demanding sealing.

How does Viton compare to Buna-N?

Viton handles higher temperatures and a much broader range of chemicals than Buna-N, but costs more. Choose Viton for heat and chemical breadth, Buna-N for economical oil sealing.

What chemicals does Viton resist?

Viton resists most fuels, oils, acids, and solvents. Its main weaknesses are ketones, hot water/steam, and low-temperature flexibility.

What temperature range does Viton handle?

−15°F to 400°F, with short excursions to 600°F.

Is Viton the same as FKM?

Viton is a brand name for FKM fluoroelastomer, so you may also see this material called FKM.

How accurate are your Viton gaskets?

CNC cut (laser, waterjet, and more) to ±0.015″. Viton parts go up to 18″ × 12″ in every thickness.

How fast do they ship?

Ships in one business day. Large orders may take longer.

Which material should I pick?

Full comparison on our Materials Guide.

Hot parts with oil or fuel (engines, exhaust) → Viton (FKM)
Hot parts, no oil (ovens, HVAC) → Silicone
Oil or fuel (pumps, hydraulics, petroleum) → Buna-N (Nitrile) — or Viton for higher heat
Water / outdoor / sun → EPDM
General automotive or light oil → Neoprene
Chemicals / aggressive fluids → PTFE (Teflon) — or Viton for high heat plus chemicals
Soft seal / uneven surfaces / low pressure → Cork blends

Not sure which material fits? Email us at fastestgaskets@gmail.com.

We CNC cut (laser, waterjet, and more) to ±0.015″. Up to 32.5″ × 32.5″ for most materials; the quote tool shows the exact limit for the one you pick. Ships in one business day. Large orders may take longer.

How to measure

Measure the outside size — diameter for rounds, or length × width for rectangles and squares.
Measure the inside opening and any holes (ID, bolt holes, bolt circle if it is a flange).
Note the thickness you need — pick it in the quoter.
Enter sizes in inches.
