Neoprene Rubber Washers
Neoprene (chloroprene, CR) is the general-purpose elastomer for washers that need moderate resistance to oil, ozone, weather, and refrigerants without specifying a premium compound. Cannon Gasket die-cuts custom neoprene washers for HVAC, refrigeration, weatherstrip, marine, and outdoor industrial sealing. Available in commercial, high-grade, military-spec, FDA, and cloth-inserted grades.

Properties of Neoprene rubber washers
Cannon Gasket cuts Neoprene rubber washers to your drawing specifications in durometers ranging from 10A to 90A Shore hardness. Moderate resistance to oils, greases, solvents, ozone, UV, water, and refrigerants.
Neoprene tolerances and customization
Standard dimensional tolerances on Neoprene rubber washers 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 in Washer Applications
- Moderate resistance to oils, ozone, UV, and refrigerants. - Available in solid and sponge / foam grades.
Common Washer Applications
HVAC and refrigeration sealing washers, weatherstrip washers in outdoor enclosures, marine and pool equipment, automotive aftermarket sealing, and applications mixing several mild exposures.
When Another Material Is the Better Specification
Buna-N for sustained oil exposure. EPDM for sustained UV / ozone or steam. Viton for aggressive chemicals.
Manufacturing Methods
Die-cut and lathe cut. Available with PSA 1 or 2 sides. Clean room manufacturing
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.
