Value Collection ZMSCH90132 O-ring Dash 132 Nitrile 50 Pack

Product Description

The VALUE COLLECTION ZMSCH90132 is a Dash 132 Nitrile Butadiene Rubber (Buna-N) O-ring used to create static and dynamic fluid seals in hydraulic, pneumatic, and mechanical assemblies. It measures 1.75 inches inside diameter, 1.938 inches outside diameter, and 0.094 inches thick with a round cross section. Rated at 90 durometer (extra hard), it handles an operating temperature range of -40 to 250 degrees F. Compatible with petroleum-based fluids, this O-ring delivers strong resistance to compression set, tearing, and abrasion. It is sold in a pack of 50 and is a widely specified size for industrial and fluid-system maintenance applications.

This O-ring is suited for use in hydraulic lines, fuel systems, pumps, valves, cylinders, and fittings where petroleum-product exposure is expected. The 90 durometer hardness makes it appropriate for higher-pressure applications requiring minimal deformation under load. Plumbers, HVAC technicians, millwrights, and industrial maintenance personnel commonly stock this size for repairs and preventive maintenance. The Dash 132 designation is a standard AS568 size reference, making sourcing and cross-referencing straightforward across suppliers and OEM documentation.

Key Features

• Buna-N (Nitrile Butadiene Rubber) material offers excellent resistance to petroleum products, oils, and fuels
• 90 durometer extra-hard rating resists deformation under pressure loads
• Operating range of -40 to 250 degrees F suits a broad range of service environments
• Round cross section provides reliable sealing in standard O-ring grooves
• Meets SAE and MIL-Spec standards for dimensional and material compliance
• Pack of 50 supports shop stock, bulk repair kits, and preventive maintenance inventory

Compatibility

Designed for use in systems and assemblies that contact petroleum products, oils, and fuels. Compatible with standard AS568 Dash 132 O-ring groove dimensions. Not recommended for use with ozone-generating equipment, direct sunlight exposure, or fluids outside the listed chemical compatibility range.

Installation Notes

Installation should be performed by a qualified technician following the equipment manufacturer's service procedures. Depressurize and isolate the system before removing old O-rings or installing new ones. Lubricate the O-ring with a compatible fluid or assembly lubricant before seating to prevent twisting or tearing during installation. Avoid storing unused O-rings near motors, electrical equipment, or direct sunlight, as ozone and UV exposure degrade Buna-N material over time.
