Neoprene Rubber Gaskets

Neoprene (chloroprene, CR) is the original synthetic rubber and remains a versatile mid-range elastomer for applications that need moderate resistance to a range of conditions without specifying a premium compound. Cannon Gasket die-cuts custom neoprene gaskets for HVAC, refrigeration, weatherstripping, and general industrial sealing. Available in commercial, high-grade, military-spec, FDA, and cloth-inserted grades.

Properties of Neoprene gaskets

Cannon Gasket cuts Neoprene gaskets to your specifications in durometers ranging from 10A to 90A Shore hardness. Moderate resistance to oils, greases, solvents, and some chemicals. Good weather and ozone resistance.

Neoprene tolerances and customization

Standard dimensional tolerances on Neoprene 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 Neoprene 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 Neoprene Performs Across Mixed Environments

- Moderate resistance to ozone, UV, weather, oils, greases, and refrigerants. - Good flame resistance compared to other general-purpose elastomers. - Available in durometers from 10 to 90 Shore A and in sponge / foam grades.

Where Neoprene Gaskets Are Specified

HVAC and refrigeration systems, outdoor industrial enclosures, weatherstripping, automotive aftermarket sealing, marine assemblies, and applications that need a mid-range elastomer at moderate cost.

When to Choose Another Material

For aggressive oil exposure, Buna-N. For sustained outdoor or steam service, EPDM. For aggressive chemical or high-temperature work, Viton. Neoprene is the right choice when the application mixes several mild exposures and a premium compound is not justified.

Manufacturing Methods

Die-cut, rotary-cut, and steel-rule-cut. Available in solid rubber and sponge / foam grades. PSA backing common for HVAC gasket applications.

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 Neoprene 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 Neoprene gaskets?
From prototype to production, any shape, any volume.
