Value Collection ZMSCH70MD210 O-ring Dash 210 Nbr 25-pack

Product Description

The VALUE COLLECTION ZMSCH70MD210 is a Dash 210 Buna-N (nitrile butadiene rubber) O-ring packaged in a quantity of 25. It measures 0.734 inches inside diameter, 1.000 inch outside diameter, and 0.125 inches thick with a round cross section. Rated at 70 Shore A hardness, this O-ring is the most widely used elastomer type in trade and industrial applications. It delivers reliable compression set resistance, tear resistance, and abrasion resistance. The working temperature range spans -40 degrees F to 250 degrees F. Licensed plumbers, HVAC technicians, and maintenance mechanics install this type of seal wherever petroleum-based fluid compatibility is required.

Dash 210 Buna-N O-rings are used across residential and commercial applications including hydraulic fittings, pneumatic assemblies, refrigerant line fittings, fuel system connections, and plumbing valve stems. The 0.734-inch ID and 1.000-inch OD dimensions make this a standard size suited for a wide range of threaded and face-seal gland configurations. This pack of 25 units suits both bench-stock replenishment and jobsite kits where multiple seals may be needed during a service call.

Key Features

• Buna-N elastomer offers excellent resistance to petroleum products including oils, fuels, and hydraulic fluids
• 70 Shore A hardness rating provides a balance of flexibility and compression set resistance
• Wide temperature range from -40 degrees F to 250 degrees F suits most HVAC, plumbing, and mechanical applications
• Round cross section with 0.125-inch thickness conforms to standard Dash 210 gland dimensions
• Pack of 25 supports multi-unit service work and shop stock replenishment
• Store away from direct sunlight, ozone sources, and electrical motors to preserve elastomer integrity

Compatibility

Designed for use in standard Dash 210 O-ring glands where Buna-N elastomer and petroleum-fluid compatibility are required. Suitable for hydraulic, pneumatic, fuel, and general-purpose fluid sealing applications. Not FDA approved for direct food contact. Metal detectable FDA information is noted in supplier documentation.

Installation Notes

Licensed plumbers, HVAC technicians, and hydraulic system mechanics typically install O-rings of this type. Depressurize and isolate the system before breaking any fitting or valve. Inspect the gland bore and mating surface for nicks or scoring before installing a new seal. Lightly lubricate the O-ring with a compatible fluid or O-ring lubricant to ease installation and prevent rolling or tearing. Do not store stock seals near motors, compressors, or other ozone-generating equipment.
