Value Collection ZMSCH70035 O-ring Dash 035 Nbr 100-pack

Product Description

The VALUE COLLECTION ZMSCH70035 is a Dash 035 Nitrile Butadiene Rubber (NBR/Buna-N) O-ring with a round cross section, sized at 2.25 inches inside diameter, 2.375 inches outside diameter, and 0.0625 inches thick. It carries a 70 Shore A hardness rating, placing it in the hard range for general-purpose sealing. NBR is the most widely used O-ring elastomer in trade applications, offering reliable resistance to petroleum-based fluids, strong compression set performance, and solid tear and abrasion resistance. Sold in a package of 100 units. Installation is performed by licensed plumbers, HVAC technicians, and fluid system mechanics.

This O-ring is suited for use in hydraulic systems, pneumatic assemblies, fuel handling lines, and fluid transfer connections where petroleum product exposure is expected. Its temperature range of -40 degrees F to 250 degrees F makes it appropriate for a wide variety of residential and commercial service environments. It meets SAE and MIL-Spec standards. Store away from direct sunlight and sources of ozone such as motors or electrical equipment.

Installation Notes

O-rings are typically installed by licensed plumbers, HVAC technicians, or hydraulic system mechanics. Always depressurize and isolate the system before replacing any sealing component. Inspect the gland groove for wear or damage before seating the new O-ring. Avoid twisting or rolling the O-ring during installation, and do not store unsealed units near motors, ozone-generating equipment, or in direct sunlight.
