Value Collection ZMSCH70FDA128 O-ring Dash 128 Nbr Fda 25pk

Product Description

The VALUE COLLECTION ZMSCH70FDA128 is a Dash 128 O-ring manufactured from white Nitrile Butadiene Rubber (NBR), commonly known as Buna-N. It measures 1.487 inches inside diameter, 1.688 inches outside diameter, and 0.0937 inches (3/32 inches) thick, with a round cross section and a Shore A hardness rating of 70. This O-ring carries FDA approval and meets SAE and MIL-Spec standards, making it suitable for use in fluid-handling systems where food-grade or compliance-grade sealing materials are required. Plumbers, pipefitters, and fluid-system technicians use this part to seal hydraulic, pneumatic, and fluid connections across a wide range of commercial and industrial applications.

This O-ring is used in plumbing, hydraulic, and pneumatic assemblies where petroleum-based fluid compatibility and reliable compression sealing are required. Its white FDA-approved NBR compound is commonly specified in food processing equipment, beverage dispensing systems, and sanitary fluid lines where incidental contact with regulated substances is a concern. Each purchase includes a pack of 25 O-rings, supporting maintenance kits, repair inventories, and production-line use. The temperature range of -40 degrees F to 250 degrees F makes it appropriate for both ambient and elevated-temperature service environments.

Key Features

• FDA-approved white NBR compound suitable for food-grade and sanitary fluid systems
• Meets SAE and MIL-Spec standards for dimensional and material compliance
• Excellent resistance to petroleum-based products, including oils and hydraulic fluids
• Good compression set, tear resistance, and abrasion resistance for long service life
• Operating range of -40 degrees F to 250 degrees F covers a broad range of service conditions
• Round cross section, Dash 128 designation — drops into standard Dash 128 groove dimensions

Compatibility

Compatible with petroleum-based products and designed to fit standard Dash 128 O-ring groove dimensions per SAE and MIL-Spec standards. Not recommended for exposure to direct sunlight, ozone, or electrical equipment that generates ozone during storage or service.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, hydraulic technician, or fluid-system mechanic. Depressurize and isolate the system before removing the existing seal. Lightly lubricate the O-ring with a compatible fluid or grease before seating it in the groove to prevent pinching or tearing during assembly. Do not install this NBR compound in systems containing ketones, esters, chlorinated solvents, or strong acids, as these media are outside its chemical compatibility range.
