Darco Southern, Inc. manufactures PTFE envelope gaskets in three standard envelope
styles and with almost any combination of filler materials. Fillers and envelopes are
also available individually for customer assembly.
Style 110 designates a slit or V-type envelope. Style 115 is a machined or milled center
envelope. Style 100 is a form shield envelope for use where large ID, OD, or oval shape
openings cannot be satisfied by a slit or milled type envelope.
When ordering PTFE envelope gaskets, the numeric designation for the envelope, fol-
lowed by the alpha material designation and filler thickness will assure our supplying
the proper item.
Example: Style 110-BSB-3/16: a slit envelope with Tetrablue 1/16 thick on each side
of a corrugated steel.
Illustrations and descriptions shown below cover the standard line of envelope gaskets
available. In addition, full-face fillers and/or envelopes are also available, factors for
pricing are shown on individual price pages. • Unless otherwise indicated on customer
order, Old Standard sizes will be furnished.
*UNLESS OTHERWISE SPECIFIED ON ORDER, OLD STANDARD SIZES WILL BE SUPPLIED
