Value Collection ZMSCH90033 O-ring 2in Id Nitrile Dash 033

Product Description

The VALUE COLLECTION ZMSCH90033 is a Buna-N (nitrile butadiene rubber) O-ring used to create reliable fluid and gas seals in hydraulic, pneumatic, and mechanical systems. It measures 2 inches inside diameter by 2.125 inches outside diameter with a 0.0625-inch (1/16-inch) cross-section thickness. Shore hardness is rated at 90 durometer, placing it in the extra-hard category for applications where higher pressure and compression resistance are required. The black, round cross-section ring operates across a temperature range of -40 to 250 degrees F and is compatible with petroleum-based fluids. Plumbers, HVAC technicians, hydraulic system technicians, and industrial maintenance professionals install this type of O-ring in sealing applications where fuel oils, lubricants, and hydraulic fluid contact is expected.

This O-ring is suited for use in residential and commercial fluid handling systems, hydraulic cylinders, pneumatic fittings, valve stems, and pump housings where petroleum-product compatibility is required. Its extra-hard 90 durometer rating makes it appropriate for higher-pressure sealing environments where softer elastomers would extrude or deform. It carries SAE and MIL-Spec standard references. This item is packaged in quantities of 100 per package with a minimum order quantity of 1.

Key Features

• Buna-N (nitrile butadiene rubber) material with excellent resistance to petroleum products including fuel oils and hydraulic fluids
• 90 durometer extra-hard rating provides strong compression set resistance and reduced extrusion under pressure
• Wide service temperature range: -40 to 250 degrees F
• Round cross-section, Dash 033 standard sizing: 2 inches ID x 2.125 inches OD x 0.0625 inches thick
• Good tear and abrasion resistance for demanding mechanical sealing environments
• Meets SAE and MIL-Spec standards

Compatibility

Compatible with petroleum-based products including hydraulic fluids, fuel oils, and lubricants. Designed as a standard Dash 033 Buna-N O-ring for use in hydraulic, pneumatic, and mechanical sealing applications. Not FDA approved; not recommended for food-contact applications. Store away from direct sunlight and ozone-generating equipment such as electric motors.

Installation Notes

Installation should be performed by qualified technicians following applicable industry codes and equipment manufacturer guidelines. Depressurize and de-energize any hydraulic, pneumatic, or fluid system before replacing O-ring seals. Lubricate the O-ring with a compatible fluid prior to installation to reduce the risk of tearing or rolling during assembly. Do not expose Buna-N O-rings to ozone sources or direct sunlight during storage, as this accelerates material degradation.
