Benefits & Applications
- Excellent Oil & Fuel Resistance
Buna-N is well-suited for environments exposed to petroleum products, lubricants, and many hydraulic fluids—making this sheet ideal for gaskets or seals in engines, pumps, or fluid systems. - Flexible & Resilient
At 50A hardness, it offers a balance between flexibility and firmness: soft enough to conform under light pressure, but firm enough to maintain its shape. - Thin & Compact for Precision Fitting
The 1/32″ thickness enables fine adjustment in clearance or matching tight tolerances without bulk. - Good for Seals, Gaskets & Liners
Use as custom gaskets, sealing pads, bearing isolators, vibration dampeners, or protective liners. - Cut-to-Size & Easy to Work
Can be cut, punched, laminated, or shaped using standard tools (e.g. utility knives, shears, die cutting).
Usage & Handling Tips
- Surface Prep
Clean both mating surfaces before placing the sheet to ensure proper sealing performance. - Cut Edges Cleanly
Use a sharp blade or die to avoid jagged edges which may compromise sealing or allow leaks. - Adhesive Bonding
Use compatible adhesives (rubber cement, contact adhesive, or vulcanizing cement recommended for nitrile) if bonding to surfaces or backing plates. - Compression Guidelines
Avoid over-compression, which can lead to permanent deformation or extrusion—maintain recommended gasket compression levels. - Storage
Store flat, in a cool, dry place, away from direct sunlight, ozone, and radical sources (e.g. strong oxidizers) to prevent aging. - Verify Supplier Data
Because “commercial-grade” specifications vary, always check the product sheet from your supplier for precise tensile strength, elongation, temperature limits, and chemical compatibility.
