HNBR Rubber O Ring Size Power Steering Engine Pump Seals The
Perfect Combination for Customers
Type: O Ring
Size: ID X CS, OD=ID + 2XCS
An o-ring is a simple and versatile ring-shaped packing or sealing
device with a circular cross section (from
which the "O" in its name is derived). The purpose of using O-ring seals is to
prevent leakage and loss of liquids
or gases. They simplicity,convenience, and small installation space. As long as the groove
design and material
selection are correct, and the operating conditions are within the temperature range of the rubber material,
the
seal can have a long-term sealing effect in the static or dynamic seal.
The size of o-ring is determined by the inner diameter ID and the
wire diameter CS. O-ring size calculation:
outer diameter = inner diameter + 2 x wire diameter (OD = ID + 2x
CS).

Hydrogenated Nitrile Butadiene Rubber (HNBR), also known as Highly
SaturatedNitrile (HSN), is
special class of nitrile rubber (NBR) that has been hydrogenated to increase saturation of
the
butadiene segment of the carbon polymer backbone. Subsequent improvements to the material
properties, over that of a nitrile rubber (NBR), include greater thermal stability, broader chemical
resistance, and greater tensile strength.
HNBR is classified by ASTM as a DH-type polymer. This
classification indicates 150ºC service
temperature as well as less than 30% swell in IRM 903 oil. HNBR can be formulated to meet
application temperatures ranging between -50°C and 165ºC.
We have certificates :ISO 9001:2015 , ISO 14001:2015 ,ISO
45001:2018 , IATF , FDA, REACH,ROHS, SGS etc.
