Usa Industrials BULK-RS-H40-278 Buna-n Rubber Strip

Product Description

The USA INDUSTRIALS BULK-RS-H40-278 is a stock-length Buna-N rubber strip used for sealing, gasketing, cushioning, and vibration isolation in industrial and mechanical applications. At 40 Shore A durometer, it offers a soft, flexible feel suited for low-compression sealing tasks. The strip measures 4 inches wide by 60 inches long and is rated for continuous service between -20 degrees F and 170 degrees F. Tensile strength is rated at 800 to 1000 psi. Tradespeople and maintenance professionals cut this material to length on-site using standard utility knives or die-cutting equipment.

This Buna-N rubber strip is appropriate for use in HVAC systems, plumbing mechanical rooms, pump housings, equipment pads, and general industrial environments where oil resistance and moderate temperature range are required. It is commonly used as a base isolation material, door and panel sealing strip, or custom gasket stock. The 60-inch stock length allows for multiple cuts from a single piece, reducing waste in service applications.

Key Features

• Buna-N (nitrile) rubber construction provides good oil, fuel, and grease resistance
• 40 Shore A durometer for soft, flexible sealing and cushioning performance
• Tensile strength of 800 to 1000 psi for reliable mechanical integrity under compression
• Operating temperature range of -20 degrees F to 170 degrees F suits most HVAC and plumbing environments
• Stock length of 60 inches allows field trimming without additional fabrication lead time
• Black color provides standard UV-stable finish for indoor and sheltered outdoor use

Compatibility

Designed as a general-purpose rubber strip for use as sealing, gasketing, or isolation material in HVAC, plumbing, and industrial mechanical applications where Buna-N nitrile rubber is the specified material.

Installation Notes

Cut to length using a sharp utility knife, straight edge, or die-cutting press. Ensure mating surfaces are clean and free of oil or debris before applying as a gasket or seal. When used as equipment isolation padding, verify that the durometer rating meets the load requirements for the specific application. No special certifications or licensed trade are required for general installation, though compliance with applicable mechanical codes should be confirmed for pressurized or code-governed systems.
