GEAR GUIDE

O-RINGS 

Materials 

Nitrile (Acrylonitrile-Butadine Copolymers) (usually black) – Good physical properties for diving applications, is not considered oxygen compatible.
 
Viton (Fluorocarbon Elastomers) (usually brown) – Required for oxygen clean applications. There is some controversy because it degrades quickly (including flaking) and is toxic when burned.
 
Polyurethane (white) – Sometimes used for the face of K-valves, very tough but sensitive to UV light so damaged by exposure to sunlight. 
WARNING: material cannot be identified by colour.
 
Common sizes used in scuba diving 

Two dimensions describe the size of an O-ring: its inside diameter and its cross-sectional diameter (CS). 
O-rings are described according to AS568B Aerospace Size Standard for O-rings, published by the Society of Automotive Engineers. AS568B lists the sizes of o-rings in six series or groups. The first five series are based on cross-sectional diameter.  
 
O-rings are identified by a 3 digit number: the first digit identifies the series (i.e. the cross-sectional diameter/CS), the second 2 digits are an identifier of the o-ring from the list and not a measurement.  O-rings are listed in order of size, so a smaller 2 digit identifier will refer to an o-ring with a smaller inside diameter. 
For scuba diving, we use o-rings from the 0XX series (CS 1.78mm | 0.07in), 1XX series (CS 2.62mm | 0.103in), and 2XX series (CS 3.53mm | 0.139in).
