O-Rings

O-Rings available in five different compositions

O-Rings are available in five different materials from Scientific Instrument Services. Each type has its advantages and disadvantages as listed in the chart below, and the type required depends on the O-Ring application. Of the various types of O-Rings available from SIS, Viton is the most popular for mass spectrometers and other laboratory instruments. This is due to Viton's high temperature stability and good resistance to chemicals and ozone.

On the following pages, O-Rings are listed by both nominal and actual size. The nominal size is the closest fractional dimension to which the O-Ring is tooled and manufactured. During manufacture the O-Rings shrink in size during the curing process. This accounts for the slight differences between the nominal and actual sizes. The I.D. is the inside diameter and the width (W) is the thickness of the O-Ring material. Order O-Rings by using the part number prefix listed in the table below followed by the standard size number listed first in the O-Ring tables, i.e. V-110 for 3/8" Viton O-Ring.

O-Ring Properties-* use this prefix in front of the size number when ordering O-Rings, i.e. V-110 for Viton size 3/8" ORing.
