The Interface Performance Materials product line
Interface compressed-fiber gaskets are a long-running standard in industries that need a non-asbestos cellulose or aramid-based gasket with a specific binder chemistry. Interface publishes an ASTM F-104 designation on every datasheet so the buyer can cross-reference density, compressibility, recovery, tensile, and fluid-resistance numbers against competing materials.
We cut all 36 grades below. Pick the family by application, then the specific code by service media. If you are cross-referencing a gasket already specified by an OEM or prior supplier, the PDF link on each row pulls the supplier datasheet.
Interface is part of our non-asbestos gasket program. If you are not sure which Interface compound fits your flange or service, start with the gasket material selection guide or send us the drawing and media list.

Not sure which grade fits?
Interface’s 36-grade catalog is deep because the binder chemistry, fiber content, and cure state all drive performance. The short version of how to narrow down:
- Oil, fuel, or coolant contact? Start in the nitrile-bound family (CN-705, N-8090, NI-2085, NV-565) or step up to the TN series if the flange is also hot.
- Cylinder head or manifold? NI-2095A, NI-2096, NI-2097A, NI-2098, NI-2900, and NI-4002 are purpose-built for cylinder-head facing, often bonded to a steel core.
- Water or dilute chemistry? Use the controlled-swell TS series or the standard SBR-bound grades (2331, CS-301, S-207, SV-360) for lower-duty water service.
- Light-duty or prototype? 2331 or N-8051 cover general-purpose, low-pressure use without the cost of the aramid-reinforced grades.
If you already know the competing supplier part you’re cross-referencing (for example a Garlock, Thermoseal, or Armstrong code), send us the number and we’ll quote the Interface equivalent. Engineering help is on the phone at 909.355.1547.

Common questions about Interface gasket grades.
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 Interface Performance Materials grades do you stock?
All 36 published grades. Standard cellulose with SBR binder (2331, CS-301, S-207, S-8091, SV-360), nitrile-bound cellulose (CN-705, N-8090, NI-2085, NV-565, PF-4N, RN-8011), cylinder-head facings (NI-2095A, NI-2096, NI-2097A, NI-2098, NI-2900, NI-4002), TN series aramid+nitrile, TS series aramid+SBR, and Pro-Formance.
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 Interface family is right for my application?
Oil/fuel/coolant at moderate temperature: nitrile-bound cellulose (CN-705, N-8090, NI-2085). Cylinder head or manifold: NI-2095A, NI-2096, NI-2097A series. Water or dilute chemistry: TS series or standard SBR-bound (2331, CS-301). Heavy-duty aramid reinforcement: TN series.
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 Interface gaskets?
Send a drawing, a part number, or a competing supplier code. We quote pricing, tooling, and lead time inside one business day.
