Properties of Klingersil® gaskets

Cannon Gasket cuts Klingersil® gaskets to your drawing in durometer and thickness specifications of 0.016" to 0.125" thickness. Excellent resistance to oils, fuels, steam, water, and most industrial chemicals. Broad media compatibility across oil & gas, chemical processing, and industrial piping.

Klingersil® tolerances and customization

Standard dimensional tolerances on Klingersil® 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 Klingersil® 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 Klingersil Performs

- High-pressure and high-temperature flange sealing — continuous service to - Resistance to steam, hydrocarbons, hot water, gases, and many chemicals depending on grade. - Reinforced grades available for the most demanding bolt loads. - Grade selection — C-4400 (general purpose), C-4401 (steam), C-4500 (acid), and specialty grades for specific service.

Where Klingersil Gaskets Are Specified

Refinery, petrochemical, power plant, marine, and process industry pipe flanges where the specification calls out Klinger or a compressed-fiber sheet of equivalent performance.

Cutting Methods

Die-cut and steel-rule-cut to flange drawings — ring gaskets, full-face gaskets, and custom shapes. Klinger material specification preserved through the cutting process.

Frequently Asked Questions

Common Klingersil® 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 Klingersil® gaskets?
From prototype to production, any shape, any volume.
