Our Story

Built on precision.
Sustained by quality.

Cannon Gasket, Inc. began in 1971 with a single press and a primary product of die-cut washers. With hard work and high expectations, Jim and Bill Cannon brought the company to a higher level by adding specialized machinery and hiring dedicated employees, working to increase their share of the gasket market while providing the highest level of customer service.

In 1981, Billy Cannon Jr. took over the business and pursued the goal of providing very competitive pricing while striving to exceed customer quality expectations. Customer service remains a priority, achieved through new technology, specialized equipment, improved quality, and employee training.

Today, Cannon Gasket is an ISO 9001 certified manufacturer serving OEMs domestically and globally, with capabilities spanning precision die cutting, rotary die cutting, lathe cutting, machining, in-house tooling, pad printing, kitting, and clean room manufacturing. With over 100 years of combined experience, the company has become an industry leader and primary vendor for hundreds of companies worldwide.

Frequently Asked Questions

Common questions about Cannon Gasket.

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.
What class clean room do you operate?
ISO 7 / Class 10,000 clean room. HEPA filtration, room pressure monitoring, airflow monitoring, and controlled temperature and humidity. Used for medical device, FDA, pharmaceutical, semiconductor, and aerospace critical-seal programs.
Do you provide lot traceability?
Yes. Every production run is tied to a work order, material lot, operator, and inspection record. Full genealogy from raw stock to finished part is retrievable on request, and is standard on aerospace and medical programs.
How big is Cannon Gasket?
Mid-sized independent manufacturer. Large enough to run high-volume OEM programs (JIT / VMI / Kanban), small enough that the engineer you talk to is the same one who reviews your drawing and approves your first article.
How do I reach an engineer?
Call 909.355.1547 during business hours (Mon-Fri 7am-4pm PT), email sales@cannongasket.com, or submit an RFQ at /request-more-information/. We respond within one business day.
How long has Cannon Gasket been in business?
Since 1971. Family-owned, in-house tooling department, production and engineering under one roof at our Fontana, California facility.
What inspection documentation do you provide?
First Article Inspection Reports (FAIR), Certificates of Conformance, Material Certifications, PPAP documentation on request, and RoHS / REACH compliance statements. Dimensional inspection uses calibrated instruments with NIST-traceable cal records.
Where are you located?
7784 Edison Ave, Fontana, CA 92336. Production, engineering, and tooling are all in the same building. Shipping nationwide and to OEM customers globally.
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.
