Product Specification

-
HSN90159 is an AS568-159 green HNBR (Hydrogenated Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 4.987 in (126.67 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 5.193 in (131.9 mm). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

It resists modern refrigerants, heat and oxidation, and petroleum oils and fuels. HNBR (Hydrogenated Nitrile) is specified for excellent abrasion and tear strength, the oil resistance of nitrile with substantially better heat capability. Rated temperature range runs from -40°F (-40°C) to 325°F (162.8°C) in continuous service.

Typical settings include engine timing systems, automotive air conditioning, and commercial refrigeration.

HSN90159 ships individually. Nominal inside diameter is listed as 5 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
