Value Collection ZMSCH2.5X10 Nitrile O-ring 10in Id

Product Description

The VALUE COLLECTION ZMSCH2.5X10 is a round-cross-section Buna-N (Nitrile Butadiene Rubber) O-ring sized at 10 inches inside diameter, 15 inches outside diameter, and 2.5 inches thick. It carries a Shore A hardness rating of 70, placing it in the hard range, and is rated for service from -40 degrees F to 250 degrees F. This O-ring seals against petroleum-based fluids and is a standard choice for hydraulic systems, pneumatic assemblies, fluid transfer lines, and mechanical seals across HVAC, plumbing, and industrial applications. Licensed tradespeople and maintenance technicians install this type of sealing component during system assembly, overhaul, and preventive maintenance work.

This O-ring is suited for residential and commercial applications where petroleum-product resistance is required. Typical installations include pump flanges, valve bonnets, pipe unions, and hydraulic cylinder end caps. Its Buna-N elastomer construction makes it one of the most broadly applied O-ring materials in trade work, offering reliable performance in oil, fuel, and water-glycol environments. It conforms to SAE and MIL-Spec standards, making it appropriate for both commercial mechanical systems and specification-driven projects.

Key Features

• Buna-N (Nitrile Butadiene Rubber) construction — the most widely used O-ring elastomer in trade applications
• Rated -40 degrees F to 250 degrees F operating temperature range
• Shore A hardness of 70 for firm compression set and durable sealing
• Excellent resistance to petroleum products, oils, and fuels
• Round cross-section profile for consistent groove seating
• Meets SAE and MIL-Spec standards

Compatibility

Compatible with petroleum products and petroleum-based fluids. Designed as a standard round-cross-section O-ring for use in hydraulic, pneumatic, and fluid-transfer sealing applications where Buna-N elastomer is specified. Not FDA approved — not intended for food-contact or potable water service.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified maintenance mechanics. Always depressurize and isolate the system before removing or installing sealing components. Lubricate the O-ring with a compatible fluid or grease prior to installation to prevent tearing and ensure even seating. Do not store Buna-N O-rings in direct sunlight or near motors, generators, or other equipment that produces ozone, as ozone exposure degrades nitrile elastomers.
