Rubber Seals

Lavelle offers standard types of Rubber Seals. Rubber Seals are manufactured in BUNA N rubber for superior resistance to water swell, steam and abrasion. The Rubber O-ring sizes that are included on this site are those of AS 568A, “Aerospace Size Standard for O-Rings”, which is generally considered to be the US size standard. However, many other sizes, both metric and nonstandard, are available. The O-Rings in the following charts are grouped by cross section (C/S) and by ascending inside diameter (I.D.). Tolerances are per industry standards.
