Usa Industrials BULK-RS-H40-78 Buna-n Rubber Strip 40A

Product Description

The USA INDUSTRIALS BULK-RS-H40-78 is a Buna-N (nitrile) rubber strip rated at 40 Shore A durometer, finished in black. It measures 120 inches long, 0.5 inches wide, and approximately 0.03 inches thick. Buna-N compound provides strong resistance to oils, greases, fuels, and petroleum-based fluids, making it a go-to material for sealing, gasketing, and cushioning applications in industrial and mechanical environments. The strip ships as a single piece and is commonly cut to length on the job by technicians, mechanics, or maintenance professionals working with fluid-handling or equipment-sealing systems.

This rubber strip is suited for use in settings where contact with petroleum products, hydraulic fluids, or mild chemicals is expected. Typical applications include custom gaskets, edge guards, vibration dampening, sealing gaps around equipment enclosures, and lining surfaces exposed to fuel or oil splash. It performs reliably in both residential mechanical rooms and light commercial or industrial service environments. Its physical toughness holds up under repeated compression and moderate abrasion.

Key Features

• Buna-N (nitrile) compound rated for oil, grease, fuel, and petroleum fluid contact
• 40 Shore A durometer provides firm yet flexible cut-to-length performance
• 120-inch continuous length allows custom sizing without splicing
• Compatible with water and mild chemical exposure in addition to petroleum applications
• Black finish, single-piece unit ready for field fabrication

Compatibility

Designed as a general-purpose Buna-N rubber strip for sealing, gasketing, and cushioning applications wherever nitrile-compatible materials are specified. No specific OEM model compatibility was stated by the manufacturer for this SKU.

Installation Notes

Cut to required length using a sharp utility knife or die-cutting tool on a flat, clean surface. Ensure mating surfaces are free of oil, debris, and moisture before applying the strip as a gasket or seal. No specialized trade license is required for installation, though applications on pressurized fuel or refrigerant systems should follow applicable codes and be performed by qualified technicians. Avoid prolonged exposure to ozone, UV, or ketone-based solvents, which can degrade Buna-N compound over time.
