Value Collection ZMSCH70FDA028 O-ring Dash 028 Nbr Fda

Product Description

The VALUE COLLECTION ZMSCH70FDA028 is a Dash 028 O-ring manufactured from Buna-N (Nitrile Butadiene Rubber), one of the most widely used elastomers in fluid sealing applications. It features a 1.364-inch inside diameter, a 1.5-inch outside diameter, and a 0.0625-inch (1/16 inch) round cross section. Hardness is rated at 70 Shore A, placing it in the hard range for reliable compression set and resistance to extrusion under pressure. This O-ring carries FDA approval and meets SAE and MIL-Spec standards, making it suitable for use in food-grade, hydraulic, and pneumatic sealing applications. Licensed plumbers, HVAC technicians, and maintenance professionals install this type of seal throughout commercial and industrial service work.

This O-ring is suited for use with petroleum-based fluids, hydraulic oils, fuels, and lubricants. Its Buna-N compound provides excellent resistance to petroleum products, strong tear and abrasion resistance, and reliable performance across a working temperature range of -40 degrees F to 250 degrees F. Typical applications include pump seals, valve stems, fittings, and fluid connectors in plumbing, HVAC, and light industrial systems. The FDA-approved white Buna-N compound also fits applications where incidental food or beverage contact compliance is required. Sold in a package quantity of 10.

Compatibility

Compatible with petroleum products, hydraulic oils, fuels, and lubricants. Designed as a standard Dash 028 O-ring replacement for hydraulic, pneumatic, plumbing, and HVAC sealing applications requiring an FDA-approved Buna-N elastomer.

Installation Notes

Plumbers, HVAC technicians, and maintenance mechanics typically install O-rings of this type during valve, pump, and fitting service. De-energize and depressurize the system and relieve any residual fluid pressure before removing the old seal. Inspect the gland groove for wear, scoring, or debris before seating the new ring. Do not store unused O-rings in direct sunlight or near motors and other electrical equipment that may generate ozone, as ozone exposure degrades NBR compounds.
