The 900 series boss seals are designed to seal straight thread tube fittings when they are fastened into a boss. In this type of fitting the O-Ring is not located in a conventional rectangular groove. Rather, the seal is obtained when the gland components exert a diagonal squeeze through the O-Ring cross section.

IN SOME CIRCLES, WE'RE KNOWN AS THE RING LEADER.

An O-Ring is simply a circular sealing ring with a round cross section, usually made from an elastomeric material. The O-Ring's simple design lends itself to a multitude of sealing uses, including static and reciprocal dynamic applications, and at low speed and low pressure, rotary and oscillating applications. The O-Ring sizes listed in the chart are those of AS 568A, "Aerospace Size Standard for O-Rings," which is generally considered to be the U.S. size standard. However, many other sizes, both metric and non-standard are also available. The O-Rings in this chart are grouped by cross section (C/S) and by ascending inside diameter (I.D.). Tolerances are per industry standards.
