Product Specification

-
H3.5X195 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 195 mm (7.677 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 202 mm (7.95 in). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

As a material, Buna-N (Nitrile) is valued for low compression set under sustained load and the most widely specified general-purpose sealing elastomer. This material stands up to hydraulic fluids, many alcohols, and petroleum-based oils. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Exposure to automotive brake fluid or ozone and direct sunlight will shorten service life.

It sees regular use in automotive, fluid power, and general industrial maintenance.

Order part number H3.5X195, sold individually. Unit weight is approximately 7.32 g. Review your operating media and conditions against this specification before installation.
