Buna-N / Nitrile Lathe-Cut Washers

Precision die-cut buna-n / nitrile components. ISO 9001 certified. Fontana, CA since 1971.
Custom Buna-N (Nitrile) lathe cut washers for oil and fuel sealing. Square edges, tight ID/OD concentricity, no tooling charge.

Key Properties

  • Durometer: 40–90 Shore A
  • Oil & fuel resistant
  • Excellent compression set
  • Good abrasion resistance

Why specify Buna-N / Nitrile for lathe-cut washers?

Buna-N lathe cut washers are the right specification when the application calls for oil-resistant sealing in a thick rubber washer with a perfectly square edge. Cannon Gasket lathe cuts custom Buna-N washers from extruded NBR tube — eliminating compound die tooling cost and delivering edge squareness that die cutting cannot match.

Properties of Buna-N / Nitrile lathe-cut washers

Cannon Gasket cuts Buna-N / Nitrile lathe-cut washers to your drawing in durometer and thickness specifications of 40A to 90A Shore hardness. Excellent resistance to petroleum oils, fuels, greases, and hydraulic fluids. Not recommended for ozone, ketones, or chlorinated solvents.

Buna-N / Nitrile tolerances and customization

Standard dimensional tolerances on Buna-N / Nitrile lathe-cut washersland around ±0.010" to ±0.015" on OD and ID, depending on material durometer and thickness. Tighter tolerances are available on select grades. Cannon Gasket cuts Buna-N / Nitrile 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.

Why Lathe-Cut Buna-N Instead of Die-Cut

- Thickness — calendared sheet typically caps at 1/4 inch; lathe-cut handles thicker washers from tube stock. - Edge squareness — perpendicular faces seal flat against the mating surface. - ID-to-OD concentricity — tight without the cost of a compound die. - Tooling cost — adjustable mandrels handle a wide range of diameters without custom dies.

Buna-N Material Notes

- Excellent oil, fuel, and hydraulic fluid resistance. - Service temperature -40°F to +250°F. - Durometers 40 to 90 Shore A.

Common Applications

Fuel-system sealing washers, hydraulic flange isolators, pump body seals, automotive sealing where thickness exceeds sheet stock, and O-ring replacements where a square wall delivers a wider seal contact band.

When Another Material Is the Better Specification

Outdoor / water — EPDM. Aggressive chemicals or temperature above 250°F — Viton.
