Value Collection ZMSCH70130 O-ring Dash 130 Nbr 70

Product Description

The VALUE COLLECTION ZMSCH70130 is a Dash 130 O-ring made from Nitrile Butadiene Rubber (Buna-N), one of the most widely used elastomers in fluid-sealing applications. It measures 1.625 inches inside diameter, 1.813 inches outside diameter, and 0.0937 inches thick with a round cross section. Rated at 70 Shore A hardness, this O-ring delivers solid resistance to petroleum-based fluids, good compression set performance, and strong tear and abrasion resistance. Plumbers, hydraulic technicians, and mechanical service professionals install these in applications where reliable static or dynamic sealing is required.

This O-ring is suited for use in hydraulic systems, pneumatic assemblies, pumps, valves, fittings, and fluid-transfer components that contact petroleum-based products. The Buna-N compound performs across a wide temperature range of -40 degrees F to 250 degrees F, making it appropriate for both indoor mechanical systems and moderate-temperature industrial service. It should not be stored in direct sunlight or near motors and electrical equipment that generate ozone, as ozone exposure degrades the compound. It is not FDA approved and is not intended for food-contact applications.

Compatibility

Designed as an OEM-style replacement or service O-ring for Dash 130 groove applications in hydraulic, pneumatic, and petroleum-fluid systems requiring a Buna-N seal. Compatible with petroleum-based fluids. Not compatible with applications requiring FDA-approved or food-grade sealing materials.

Installation Notes

Depressurize and drain the system before replacing any O-ring seal. Inspect the groove and mating surfaces for wear, corrosion, or debris before installing the new O-ring. Apply a light coat of system-compatible fluid or O-ring lubricant to ease installation and reduce the risk of tearing the seal during assembly. Do not stretch the O-ring over sharp edges, and avoid twisting it in the groove.
