Value Collection ZMSCH70132 O-ring Dash 132 Nitrile 70A

Product Description

The VALUE COLLECTION ZMSCH70132 is a Dash 132 O-ring made from Nitrile Butadiene Rubber (Buna-N), one of the most widely used elastomers in fluid sealing applications. It measures 1.75 inches inside diameter with a 1.938 inches outside diameter and a 0.094 inch cross-section thickness. Rated at 70 Shore A durometer, this O-ring delivers firm compression set resistance along with strong tear and abrasion resistance. It is suited for static and dynamic sealing in plumbing, hydraulic, pneumatic, and HVAC service applications where exposure to petroleum-based fluids is expected.

This O-ring is commonly installed in hydraulic fittings, valve stems, pump housings, and fluid line connections found in residential and commercial mechanical systems. Its petroleum-product compatibility makes it a standard choice for HVAC refrigerant-adjacent assemblies, fuel systems, and general plumbing seal replacements. Installers working in pool equipment, irrigation, and industrial fluid handling also regularly use Dash 132 Buna-N O-rings in grooved and threaded port applications. The 100-piece package quantity supports field service kits and maintenance stock.

Key Features

• Buna-N (Nitrile Butadiene Rubber) construction offers excellent resistance to petroleum products and hydraulic fluids
• 70 Shore A durometer rating provides firm sealing with reliable compression set performance
• Round cross-section profile fits standard Dash 132 O-ring grooves per SAE and MIL-Spec standards
• Operating temperature range of -40 degrees F to 250 degrees F suits most HVAC, plumbing, and hydraulic service environments
• Tear and abrasion resistance extends service life in dynamic sealing applications
• Black color standard; store away from direct sunlight, ozone sources, and electrical equipment that may generate ozone

Compatibility

Designed as a standard Dash 132 O-ring replacement compatible with petroleum products and hydraulic fluids; meets SAE and MIL-Spec dimensional standards for Dash 132 groove configurations.

Installation Notes

O-rings in this size class are typically installed by licensed plumbers, HVAC technicians, and hydraulic service technicians. Always depressurize and de-energize the system before replacing any seal. Lightly lubricate the O-ring with a compatible fluid or grease before seating to prevent cutting or rolling during assembly. Do not expose Buna-N O-rings to ozone-generating equipment during storage or installation.
