Value Collection ZMSCH70214 O-ring Dash 214 Buna-n 100pk

Product Description

The VALUE COLLECTION ZMSCH70214 is a Dash 214 Nitrile Butadiene Rubber (Buna-N) O-ring sized at 1 inch inside diameter, 1.25 inches outside diameter, and 0.125 inches thick with a round cross section. Rated at 70 Shore A hardness, this O-ring handles temperatures from -40 degrees F to 250 degrees F and delivers strong resistance to petroleum-based fluids, hydraulic oils, and fuels. It is the most widely used elastomer in industrial and trade sealing applications, suited for plumbers, HVAC technicians, and mechanical contractors who need a dependable, readily available seal for fluid system components.

This O-ring is appropriate for use in residential and light commercial plumbing, HVAC refrigerant and oil circuits, and hydraulic or pneumatic assemblies where petroleum-product compatibility is required. The Dash 214 designation follows standard AS568 sizing, making it a direct fit wherever that dash number is called out on a parts list or equipment drawing. Sold in a package of 100 units, making it suitable for shop stock and field service kits.

Compatibility

Compatible with petroleum products and petroleum-based fluids. Designed as a standard Dash 214 O-ring for use in any system or fitting that specifies this AS568 dash number. Not recommended for use with ozone-generating equipment or direct sunlight storage environments.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or mechanical contractor. Shut off and depressurize the system before replacing any O-ring seal. Lightly lubricate the O-ring with a compatible fluid or grease prior to seating to avoid tearing during installation. Do not store unused rings near motors, electrical equipment, or in direct sunlight, as ozone and UV exposure degrade Buna-N material.
