Value Collection ZMSCH70FDA013 O-ring Dash 013 Buna-n Fda 25pk

Product Description

The VALUE COLLECTION ZMSCH70FDA013 is a Dash 013 O-ring manufactured from Buna-N (Nitrile Butadiene Rubber), one of the most widely used elastomers in fluid-sealing applications. It measures 0.438 inches inside diameter, 0.563 inches outside diameter, and 0.0625 inches thick with a round cross section. Hardness is rated at 70 Shore A. This O-ring carries FDA approval and meets SAE and MIL-Spec standards, making it suitable for both general-purpose and food-contact-adjacent sealing applications. Licensed plumbers, HVAC technicians, and equipment service pros install this type of seal in valves, fittings, pumps, and fluid-handling assemblies where petroleum-based fluid resistance is required. Sold in a pack of 25.

Buna-N O-rings in the Dash 013 size are commonly used in residential and commercial plumbing, HVAC refrigerant-adjacent assemblies, hydraulic fittings, and pneumatic connections. The material provides excellent resistance to petroleum products, oils, fuels, and hydraulic fluids. The FDA-approved white compound also makes this ring appropriate for equipment used in food-processing and potable-water-adjacent environments where material compliance is a requirement. Typical applications include valve stem seals, union connections, pump housings, and threaded port plugs across a wide range of trade and industrial equipment.

Compatibility

Designed as a standard Dash 013 O-ring replacement compatible with petroleum-based fluid systems. Suitable for use with petroleum products and compatible fluids. Store away from direct sunlight, ozone sources, and electrical equipment that may generate ozone to preserve elastomer integrity.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified equipment service professionals. Always depressurize and drain the system before replacing any O-ring seal. Lightly lubricate the O-ring with a compatible fluid or O-ring lubricant prior to seating to prevent tearing during assembly. Do not over-stretch the ring during installation, and inspect the seating groove for nicks or corrosion before fitting.
