Polyurethane Rubber Gaskets

Polyurethane (PU) is the elastomer of choice when abrasion resistance, tear strength, and load-bearing capacity matter more than chemical resistance or temperature range. Cannon Gasket die-cuts custom polyurethane gaskets for mining, automotive, hydraulic, and high-wear industrial sealing.

Properties of Polyurethane gaskets

Cannon Gasket cuts Polyurethane gaskets to your specifications in durometers ranging from 10A to 95A Shore hardness. Good resistance to oils, solvents, and many hydrocarbons; excellent tear and abrasion resistance.

Polyurethane tolerances and customization

Standard dimensional tolerances on Polyurethane 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 Polyurethane 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 Polyurethane Performs Under Mechanical Stress

- Exceptional abrasion and tear resistance — among the highest of any elastomer. - High load-bearing capacity at relatively thin cross-sections. - Good resistance to oils, fuels, and aliphatic hydrocarbons. - Available in durometers from 10A to 95A Shore hardness.

Where Polyurethane Gaskets Are Specified

Mining and aggregate equipment seals, hydraulic cylinder seals, vibration dampers, wear pads, automotive suspension components, and applications combining oil exposure with abrasion.

When to Choose Another Material

For high-temperature service, specify Viton or silicone. For steam or hot water, EPDM. Polyurethane should be the choice when wear and tear strength are the primary specification.

Manufacturing Methods

Die-cut

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