• The following are the nominal dimensions for Dixon's elastomeric cam and groove gaskets.
• The ID's of the Teflon® envelope gaskets and the Teflon® accordion gaskets are 1/16" smaller than the ID's for the elastomeric
gaskets shown below.
• Thicknesses of Teflon® accordion gaskets may vary from chart below.
1 No interchange standard exists for the ½" and 8" fittings. Generally, these sizes do not interchange with other manufacturer's
products. As such, the gaskets in these sizes are not suitable for use in other manufacturers' couplings.
