Fluorosilicone Rubber Gaskets

Fluorosilicone (FVMQ) is the specification when an application needs the broad temperature range of silicone but cannot tolerate silicone's susceptibility to oils, fuels, and aromatic hydrocarbons. Cannon Gasket die-cuts custom fluorosilicone gaskets for aerospace fuel-system seals, military hardware, and chemical processing applications.

Properties of Fluorosilicone gaskets

Cannon Gasket cuts Fluorosilicone gaskets to your specifications in durometers ranging from 10A to 90A Shore hardness. Excellent resistance to fuels and oils, with moderate resistance to aromatic and chlorinated solvents. Retains flexibility across extreme temperature swings.

Fluorosilicone tolerances and customization

Standard dimensional tolerances on Fluorosilicone gaskets land around ±0.010" to ±0.015" on OD and ID, depending on material durometer and thickness. Tighter tolerances are available on selected grades. Cannon Gasket cuts Fluorosilicone to custom profiles in-house and matches lead times to your production volume. PSA backing, pad printing, custom packaging, and kitting are all on the menu when you need them.

How Fluorosilicone Performs in Fuel and Solvent Contact

- Resistant to fuels, oils, aromatic hydrocarbons, and oxidizing chemicals where silicone would swell or degrade. - Effective against ozone, aromatic chlorinated solvents, and bases. - Retains the flexibility and broad thermal range of silicone.

Where Fluorosilicone Gaskets Are Specified

Aerospace fuel and hydraulic systems, aviation seals, defense hardware, semiconductor processing, and applications where silicone's temperature range is needed alongside chemical resistance.

When to Choose Another Material

If chemical contact is not a factor, silicone is the more economical specification. If temperature is below 250°F and oils are present, Buna-N is more cost-effective.

Manufacturing Methods

Die-cut and lathe cut. Available in industrial, FDA and aerospace-qualified grades.

Standard sizes, tolerances & manufacturing

Precision & tooling: Capable of holding tolerances as tight as ±.001" on critical dimensions when required, beyond the ±0.010" to ±0.015" standard. Short- and long-run capabilities. All parts available with pressure-sensitive adhesive (PSA) on one or two sides.

Clean room: Cannon Gasket offers clean-environment stamping for medical, FDA, electronic, and scientific applications where a controlled level of particulate is required, with capabilities to meet ISO Class 10,000.

Stocking agreements: Blanket orders, VMI (vendor-managed inventory), JIT (just-in-time), and Kanban replenishment programs.

Pad printing: Pad print your part number, identification marking, or company name in a range of ink colors. Marking per customer specifications or MIL-STD-130.

Packaging: Parts are bagged and tagged in specified quantities and labeled with P/N or any required information. Capability to meet specific packaging and labeling requirements.

Frequently Asked Questions

Common Fluorosilicone questions.

Are you ISO 9001 certified?
Yes, ISO 9001:2015 certified. Documented quality management covers incoming material verification, in-process inspection, calibrated measurement, final inspection, non-conformance handling, corrective action, and full lot traceability. AS9100-ready for aerospace, with MIL-spec and FDA 21 CFR 177.2600 / USP Class VI grades available on request.
Can you cut custom gasket profiles?
Yes. Custom steel-rule and rotary tooling is built in-house from your drawing or DXF. Complex profiles, multiple through-cuts, tight bolt patterns, and irregular perimeters are all standard work.
Can you supply PSA-backed gaskets?
Yes. Pressure-sensitive adhesive backing is a standard option on most rubber and fiber gasketing, with either permanent or removable liners. Kiss-cut on liner and through-cut both supported on flatbed and rotary presses.
What tolerances can you hold on gasket dimensions?
Standard die-cut tolerance is ±0.010 to ±0.015 inch on OD and ID, depending on material durometer and thickness. Tighter tolerances are available on select grades and thicknesses. Ask if your drawing specifies something tighter and we will confirm feasibility during the quote.
Which gasket material is right for my application?
Start with temperature range, fluid contact, and regulatory requirements. Buna-N is the default for oil and fuel. EPDM for weather, water, and steam. Silicone for extreme temperature and FDA grades. Viton for aggressive chemicals. Our gasket material selection guide walks through the decision framework.
How fast do you return a quote?
Most RFQs come back within one business day. Simple profile updates to an existing tool quote same-day. Send a drawing, DXF, or competing part number and our engineering team reviews material, tolerance, and volume before pricing.
What is the minimum order quantity?
Minimums depend on the part and material. We cut prototype and first-article quantities for engineering evaluation, then scale up to production volumes from the same tooling. For high-volume programs we run JIT, VMI, and Kanban replenishment out of Fontana, California.
What should I send with an RFQ?
Ideal: a drawing or DXF, material spec (or compound family), estimated annual volume, and any regulatory callouts (FDA, USP Class VI, AS9100, MIL-spec). If you only have a sample or a part number from a competing supplier, send that and we will reverse-engineer the spec before quoting.
What are typical lead times?
Prototype and first-article parts usually ship in 5-10 business days. Production runs from existing tooling are 2-3 weeks depending on volume and material lead time. Rush and expedite options available on a case-by-case basis.
Need custom Fluorosilicone gaskets?
From prototype to production, any shape, any volume.
