Value Collection ZMSCH70FDA213 Buna-n O-ring Dash 213 10pk

Product Description

The VALUE COLLECTION ZMSCH70FDA213 is a Dash 213 Buna-N (nitrile butadiene rubber) O-ring with an inside diameter of 0.921 inches, an outside diameter of 1.187 inches, and a thickness of 0.125 inches. It features a round cross section and a Shore A hardness of 70, placing it in the hard hardness range. This FDA-approved white O-ring is rated for continuous service from -40 degrees F to 250 degrees F and carries SAE and MIL-Spec compliance. It is sold in a package of 10 and is suited for use by plumbers, HVAC technicians, hydraulic system mechanics, and industrial maintenance professionals working on fluid-sealing applications involving petroleum-based media.

This O-ring is well-suited for use in hydraulic systems, pneumatic fittings, fuel handling assemblies, and plumbing connections where petroleum product exposure is expected. Its FDA-approved white Buna-N compound makes it appropriate for food-processing equipment, commercial kitchen plumbing, and potable water system components where material compliance is required. Typical install scenarios include sealing pump housings, valve stems, pipe unions, and fitting connections in both residential and light commercial settings.

Key Features

• FDA-approved white Buna-N compound suitable for food-contact and potable water applications
• Excellent resistance to petroleum products, oils, and fuels
• Round cross section with consistent 0.125-inch thickness for reliable sealing compression
• Wide temperature range: -40 degrees F to 250 degrees F
• Shore A 70 hardness provides strong compression set resistance and tear and abrasion resistance
• Meets SAE and MIL-Spec standards

Compatibility

Designed as an OEM-style replacement or service O-ring for Dash 213 groove specifications in hydraulic, pneumatic, plumbing, and fuel-handling assemblies where Buna-N (nitrile) elastomer and petroleum-product compatibility are required. Compatible material: petroleum products.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or hydraulic system mechanics. Before servicing, depressurize the system fully and shut off all fluid supply valves. Lightly lubricate the O-ring with a compatible fluid or grease before seating it in the groove to prevent rolling or tearing during assembly. Avoid storing unused O-rings in direct sunlight or near motors and other electrical equipment that may generate ozone, as ozone exposure degrades nitrile rubber over time.
