Buna-N / Nitrile Gaskets
Key Properties
- Durometer: 10A – 90A
- Oil & fuel resistant
- Petroleum & grease resistant
- Good abrasion resistance
- Good compression set
- Cost-effective elastomer
Why specify Buna-N / Nitrile for gaskets?
Buna-N, also called Nitrile or NBR, is a common elastomer in the seal and gasket industry. Cannon Gasket die-cuts custom Buna-N gaskets for applications where petroleum products, oils, fuels, hydraulic fluids, or greases are in contact with the gasket. Available in commercial, high-grade, FDA, and cloth-inserted grades.
Properties of Buna-N / Nitrile gaskets
Cannon Gasket cuts Buna-N / Nitrile gaskets to your drawing in durometer and thickness specifications of 10A to 90A Shore hardness. Excellent resistance to petroleum oils, fuels, greases, and hydraulic fluids. Not recommended for ozone, sunlight, ketones, or chlorinated hydrocarbons.
Buna-N / Nitrile tolerances and customization
Standard dimensional tolerances on Buna-N / Nitrile gasketsland 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.
How Buna-N Performs in Oil, Fuel, and Hydraulic Service
- Excellent resistance to petroleum oils, gasoline, diesel, and hydraulic fluids. - Good compression set, tensile strength, and abrasion resistance. - Available in durometers from 10 to 90 Shore A. - Cost-effective compared to fluorocarbon elastomers.
Where Buna-N Gaskets Are Specified
Fuel-system gaskets, hydraulic and pneumatic flange gaskets, pump and compressor service, automotive engine and fuel-system sealing, plumbing, and general industrial applications where petroleum contact is part of the duty cycle.
When to Choose Buna-N vs. Another Elastomer
- vs. EPDM — Buna-N for oil and fuel contact; EPDM for steam, water, and outdoor weathering. - vs. Viton — Buna-N when budget matters and temperatures stay under 250°F; Viton when chemical exposure is aggressive or temperatures exceed 250°F. - vs. Silicone — Buna-N for oil contact; Silicone for extreme high or low temperature where chemical exposure is mild.
Manufacturing Methods
Die-cut on flat-bed presses for standard runs, rotary-cut for high-volume web-fed production, and steel-rule-cut for large parts. PSA backing, clean room production, pad printing, and stocking programs are available.
