Value Collection ZMSCH70215 O-ring Dash 215 Nitrile Buna-n

Product Description

The VALUE COLLECTION ZMSCH70215 is a Dash 215 O-ring manufactured from Nitrile Butadiene Rubber, also known as Buna-N, the most widely used elastomer in sealing applications. It features a round cross-section measuring 1.0625 inches inside diameter, 1.313 inches outside diameter, and 0.125 inches thick. Rated at 70 Shore A hardness, this O-ring delivers reliable compression set resistance along with strong tear and abrasion resistance. It is suited for static and dynamic sealing in systems handling petroleum-based fluids. Licensed plumbers, hydraulic technicians, and industrial maintenance professionals commonly install this part.

This O-ring is designed for use in fluid power, plumbing, and hydraulic systems where petroleum product compatibility is required. Typical applications include pump seals, valve seats, cylinder end caps, and threaded port connections in both residential and light commercial equipment. Its operating temperature range of -40 degrees F to 250 degrees F makes it appropriate for a broad range of service environments. It complies with SAE and MIL-Spec standards, confirming dimensional and material conformance across those specification families.

Key Features

• 70 Shore A hardness rating provides firm sealing with good compression set recovery
• Operating temperature range: -40 degrees F to 250 degrees F
• Round cross-section for uniform sealing load in standard O-ring grooves
• Sold in a package quantity of 100 units with a minimum order quantity of 1

Compatibility

Designed as a standard Dash 215 replacement O-ring compatible with petroleum-based fluid systems meeting SAE and MIL-Spec dimensional requirements. Not recommended for use with ozone-generating equipment or in direct sunlight storage conditions. Not FDA approved.

Installation Notes

Installation is typically performed by licensed plumbers, hydraulic technicians, or qualified maintenance personnel. Depressurize and drain the system fully before removing the existing O-ring. Inspect the groove for nicks, burrs, or corrosion that could compromise the seal. Lubricate the O-ring lightly with a compatible petroleum-based lubricant before seating to reduce the risk of rolling or pinching during assembly.
