Value Collection ZMSCH70FDA330 O-ring Dash 330 Buna-n Fda

Product Description

The VALUE COLLECTION ZMSCH70FDA330 is a Dash 330 O-ring manufactured from Buna-N (nitrile butadiene rubber), the most widely used elastomer in fluid sealing applications. It measures 2.125 inches inside diameter, 2.5 inches outside diameter, and 0.1875 inches (3/16 inches) thick with a round cross section. Rated at 70 Shore A hardness, this O-ring is FDA approved and meets SAE and MIL-Spec standards. It is sold in packages of 10. Licensed plumbers, HVAC technicians, and industrial maintenance professionals install this part wherever a reliable petroleum-resistant seal is required.

This O-ring is suited for use in residential and commercial plumbing systems, HVAC refrigerant circuits, hydraulic assemblies, and other fluid-handling equipment that involves petroleum-based media. The Buna-N compound provides excellent resistance to petroleum products, oils, and fuels, making it appropriate for pump seals, valve stems, pipe fittings, and fluid connectors. The FDA-approved white compound also qualifies this ring for food-equipment and sanitary-process applications where material certification is required. Operating temperature range spans -40 degrees F to 250 degrees F.

Compatibility

Designed as a standard Dash 330 O-ring replacement compatible with petroleum-based fluids, oils, and hydraulic media. Compatible with petroleum products as stated by the manufacturer. 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 industrial maintenance personnel. Always shut off fluid supply and relieve system pressure before removing or replacing O-rings. Lightly lubricate the O-ring with a compatible fluid or lubricant before seating to prevent twisting or tearing during installation. Do not use petroleum-incompatible lubricants or solvents that may degrade the Buna-N compound.
