Nitrile Rubber Sheet, Buna-N 12″ × 8″ × 1/8″
Premium Nitrile Rubber (NBR) with Shore A65 hardness delivers strong resistance to fuel, oil, and petroleum-based substances. It withstands alkalis, acids, and hydrocarbon solvents, making it suitable for automotive gaskets and machinery seals. The material offers 6 MPa tensile strength and 250% elongation, maintaining flexibility from -68 °F to +176 °F. Best for: small gasket projects, static seals, and DIY repairs where fuel resistance is required. Caution: avoid extremely high-temperature environments outside the stated range.
WochiTV Nitrile Rubber Sheet, 1/8″ Thick, 12″ × 12″
This Buna-N sheet features premium NBR with Shore A65 hardness, 6 MPa tensile strength, and 250% elongation. It offers fuel, oil, gas, and hydrocarbon solvent resistance with good cushioning to absorb shocks. Best for: DIY gaskets, pads, and vibration reduction in appliances or furniture. Choose this if you need a general, versatile sheet for moderate-thickness gaskets. Limitation: larger or more complex gasket shapes may require cutting and fitting precision.
WochiTV Nitrile Rubber Sheet, 1/4″ Thick, 12″ × 12″
This heavier Buna-N sheet provides increased thickness for robust gasket applications and automotive repairs. It continues to deliver fuel and oil resistance with a -68 °F to +176 °F operating range, plus 6 MPa tensile strength and 250% elongation. Best for: thicker gaskets and payload-bearing seals where durability matters. Better for tasks requiring more structural support. Caution: the increased thickness may be less flexible for very fine-detail seals.
WochiTV Nitrile Rubber Sheet, 1/16″ Thick, 12″ × 12″
Thin Buna-N sheet that maintains Buna-N properties with good oil and fuel resistance, suitable for lightweight gaskets and seals. This option emphasizes flexibility in tight spaces. Best for: thin-gap seals, small weatherstrips, and hobbyist projects. Limitation: reduced thickness can limit sealing capability for high-pressure applications.
Nitrile Rubber Sheet, Buna-N 12″ × 12″ × 1/8″
Another 12″ × 12″ Buna-N option with identical Shore A65 hardness and same strength specs. It expands the choice for larger gaskets or evenly distributed seal areas. Best for: general gasket material and plumbing or machinery seals where a square sheet is convenient. Caution: verify exact thickness and size before cutting to ensure proper fit.
E. JAMES Buna-N Rubber Sheet, 12″ × 12″, 1/16″
E. JAMES Buna-N Sheet offers oil resistance, abrasion resistance, and good adhesion to metals in a durable, solid rubber form. The 1/16″ thickness supports lightweight gasket tasks, weatherstripping, and pads with consistent performance. Best for: small DIY seals and compatible metal-to-rubber applications. Limitation: check the product’s actual thickness tolerance for precision sealing projects.
Buying Guide: Buna-N Rubber Sheets For Sealing And Gasket Work
What matters when choosing Buna-N sheets?
- Thickness needs: Thicker sheets provide more rigidity and support; thinner sheets offer flexibility for tight gaps and delicate seals.
- Size and cutouts: Match sheet dimensions to your gasket pattern; consider extra material for precision shaping.
- Fuel and oil resistance: Buna-N performs well against petrol, oils, and many solvents; ensure the chemical exposure matches the spec.
- Temperature range: Typical Buna-N sheets operate well from sub-zero to moderate high temperatures; confirm your environment.
- Hardness and flexibility: Shore A65 offers a balance of strength and pliability for general gaskets and seals.
How to choose between thicknesses?
- 1/16″ and 1/8″ are good for thin gaskets, weatherstripping, and padding where space is limited.
- 1/4″ is better for structural seals and automotive gaskets requiring more resilience.
- 12″ × 8″ or 12″ × 12″ sheets suit pattern-based gaskets or multiple parts from a single sheet.
Practical considerations
- Cutting and finishing: Use sharp utility knives or a rotary cutter for clean edges; deburr with sandpaper if needed.
- Sealing compatibility: Some applications may require adhesives compatible with Buna-N; test compatibility first.
- Storage: Keep sheets flat and away from direct sunlight or solvents to prevent hardening or degradation.
Frequently Asked Questions
Q: Is Buna-N the same as nitrile rubber? A: Yes. Buna-N is a common designation for nitrile rubber used in seals and gaskets.
Q: What temperature range can Buna-N sheets handle? A: Typical operating range is roughly -68 °F to +176 °F, depending on formulation and exposure.
Q: Can I use Buna-N sheets for weatherstripping? A: Yes, especially the 1/16″ to 1/8″ thicknesses for door and window weatherstripping in many environments.
Q: Are there adhesives that work well with Buna-N? A: Some solvent-based or contact adhesives are compatible; always test a small area first to avoid sheet damage.
Q: Do Buna-N sheets resist gasoline exposure? A: Buna-N exhibits good resistance to fuel and oils, making it suitable for fuel-system gaskets in many cases.
Q: How should I measure and cut for a precise gasket? A: Trace the exact gasket pattern onto the sheet, use a sharp knife, and smooth edges with fine sandpaper for an exact fit.
