Value Collection ZMSCH90038 O-ring Dash 038 Nbr 50-pack

Product Description

The VALUE COLLECTION ZMSCH90038 is a Buna-N (Nitrile Butadiene Rubber) O-ring sized to Dash 038 with a 2.625-inch inside diameter, 2.75-inch outside diameter, and a 0.0625-inch (1/16-inch) cross-section thickness. Rated at 90 durometer, this extra-hard O-ring delivers firm compression set resistance and strong sealing under pressure. The temperature range spans -40 degrees F to 250 degrees F, making it suitable for demanding hydraulic, pneumatic, and fluid-transfer applications. Each package contains 50 pieces. Installation is typically performed by licensed plumbers, hydraulic technicians, and HVAC mechanics working on fluid or refrigerant sealing points.

This O-ring is commonly used in hydraulic fittings, pneumatic cylinders, fuel systems, and plumbing assemblies where contact with petroleum-based fluids is expected. The Buna-N compound offers excellent resistance to petroleum products, oils, and fuels, making it a standard choice for industrial and trade applications. The extra-hard 90-durometer rating suits high-pressure sealing scenarios where softer compounds would extrude. Supplied in a 50-piece package to support service fleets and shop inventories.

Compatibility

Compatible with petroleum products, hydraulic oils, and fuel-system fluids. Designed as a standard Dash 038 O-ring replacement for hydraulic, pneumatic, and plumbing assemblies using Buna-N-compatible sealing materials. Not FDA approved; not recommended for food-processing or medical applications.

Installation Notes

Shut down and depressurize the system completely before removing or installing any O-ring. Lubricate the O-ring lightly with a compatible fluid or O-ring lubricant before seating to prevent tearing during assembly. Do not expose the O-ring to direct sunlight during storage, and keep away from motors or electrical equipment that may generate ozone, as ozone degrades Nitrile rubber. Follow applicable system pressure ratings and torque specifications provided by the equipment manufacturer.
