Value Collection ZMSCH70FDA120 O-ring Dash 120 Nbr 25-pack

Product Description

The VALUE COLLECTION ZMSCH70FDA120 is a Dash 120 Buna-N (nitrile butadiene rubber) o-ring rated at 70 Shore A hardness and approved to FDA standards. It measures 0.987 inches inside diameter, 1.187 inches outside diameter, and 0.0937 inches (3/32 inches) thick with a round cross section. Buna-N is the most widely used o-ring elastomer in fluid-handling and mechanical sealing applications. This part carries SAE and MIL-Spec compliance and is sold in a package of 25. Plumbers, HVAC technicians, and industrial maintenance techs routinely stock this size for petroleum-fluid service.

This o-ring is suited for applications involving petroleum-based fluids, oils, and fuels in residential and commercial systems. The Dash 120 size fits a broad range of standard fittings, valves, pumps, and hydraulic components where a reliable compression seal is required. The -40 degrees F to 250 degrees F operating temperature range covers most HVAC, refrigeration-adjacent, and plumbing service environments. The white FDA-approved Buna-N compound also makes it appropriate for applications requiring food-grade compliance.

Key Features

• Buna-N (Nitrile Butadiene Rubber) compound — excellent resistance to petroleum products, oils, and fuels
• FDA approved white compound suitable for food-grade and sanitary applications
• SAE and MIL-Spec compliant construction
• 70 Shore A hardness with hard hardness rating — good tear and abrasion resistance
• Round cross section with excellent compression set characteristics
• Packed in quantities of 25 for bench-stock and service-truck replenishment

Compatibility

Compatible with petroleum products and petroleum-based fluids. Designed as a standard Dash 120 replacement o-ring for use in valves, fittings, pumps, and hydraulic components requiring a Buna-N seal. Store away from direct sunlight, ozone sources, and electrical equipment that may generate ozone.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or qualified maintenance personnel. Depressurize and isolate the system completely before removing or replacing any o-ring seal. Lightly lubricate the o-ring with a compatible fluid before seating to prevent tearing during assembly. Do not use petroleum-incompatible lubricants, and do not store unused o-rings near motors or other ozone-generating equipment.
