Folded Series
Leader Tech's Folded Gasket series are industry standard general-purpose gaskets that allow a large range of deflection and
compression forces. These gaskets are available with or without tape for alternate attachment methods. Also available in a snag-
free version where, under compression, the leading edge of the gasket slides into an extended and folded base which prevents
possible damage to the gasket.

The FSC was created to provide snag free gaskets with FS gasket features. The base of the gasket is
extended from the mounting area and then folded up, over, down, and then comes to rest over the
leading edge of the formed spring. Under compression, the leading edge of the gasket slides under
and is “captured.” This “no snag” feature is also used to prevent possible gasket damage.

When placing an order or requesting a quotation, please give part number,
your required finish I.D. from the chart below, and required length.
Leader Tech tape mounted CuBe gaskets offer pressure-sensitive, double-sided adhesive for strong bonding to
a wide variety of surface conditions. Ideal for all-purpose contact strips used in metal cabinets and electronic
enclosures and is unaffected by temperatures from -67 to +250°F (-55 to 121°C)
Simply follow these four easy steps:
1. Remove all grease and oily residue with a solvent such as isopropyl alcohol/water mixture (rubbing alcohol)
or heptane. Dry and smooth the mounting surface with emery cloth if necessary.
2. Peal off the protective paper backing from the pressure sensitive adhesive tape.
3. Place the gasket in correct position. Press firmly to ensure a good bond to surface. Avoid repositioning, which
might impair the effectiveness of the adhesive or may bend or kink the strip. NOTE: On strips where fingers
cover the solid portion of the gasket, pressure may be applied by inserting a mandrel in the strip and pressing
down.
4. At room temperature approximately 50% of the ultimate strength will be achieved after 20 minutes, 90% after 24
hours, and 100% after 72 hours. In some cases bond strength can be increased and ultimate bond strength can be
achieved more quickly by exposure of the bond to elevated temperature, e.g., 150°F (66°C) for 1 hour.
Adhesive Mounting of Fingerstock Gaskets
The above example is the “Slot Mount Series” gasket shown on page 3. The height is .11 inch and the width is .32
inch. The “-S-” indicates a soft gasket. The “SN” indicates a bright tin finish. See list below for available finishes. This
part is available in lengths of 16 inches. Consult factory for custom lengths or for availability in 25’ coils.
