This gasket uses our high shielding tin plated beryllium copper Spira-Shield as its base. We inject a liquid silicone adhesive into the center of the spiral, which hardens and bonds completely to the metal, making this gasket extremely durable when properly used.

Because of its durability, Enduro-Shield is ideal for groove-mounted sliding applications, such as in connectors. This gasket material is used in our Enduro-Shield O-rings.

Materials

Spiral: Tin/lead plated beryllium copper. (See Options for RoHS compliance). Electroplated, 90% tin, 10% lead (edges unplated).

Cord: Cured silicone adhesive.

Shielding Quality

This gasket offers shielding quality from 117 dB to 152 dB. The shielding quality may vary depending on your specific application.

Compression Force

Enduro-Shield gaskets come in three different resiliencies (as shown below). Optimal compression of the gasket is 25% of the diameter of the spiral. Since the force to compress the gasket is a function of the cube of the thickness of the beryllium copper ribbon, the compression forces shown are approximate. Some sizes are also available in low force. Please contact us for information.
Standard Force: ~30 pounds per linear inch compression.
Moderate Force: ~10 pounds per linear inch compression.
Low Force: ~1.5 pounds per linear inch compression.

Mounting

This gasket is groove mounted.

Custom Sizes

We can manufacture Enduro-Shield gaskets in any size diameter, from .034” up to .141”. There may be a nominal tooling charge for special sizes. Please contact us with your requirements.

Plating

Plating options can be specified by adding a prefix before the part number. (Not all plating options are in stock):
E: Edge tin/lead plating (includes edges) for high humidity or salt-fog environments
IW: RoHS compliant tin plating (Example: IWMS-08)
EIW: RoHS compliant edge tin plating for high humidity or salt-fog

Material

Stainless steel material may also be substituted if desired. Please contact us to specify this custom option.

Special Core

A special core can be specified by using the following option (may not be available in all sizes and may include extra charges):
-F: Solid Fluorosilicone Cord (Example: SIMS-08-F)
-O: Silicone that meets outgassing requirements
-Z: Silicone which is a non-acetic acid adhesive (per MIL-A-46146)

Note: EMI/Environmental version in development. Contact us for more information.

Ordering Information

Enduro-Shield is sold by the piece in four foot lengths. It can be spliced together to make longer lengths upon request. Enduro-Shield can also be ordered cut-to-length in specific sizes or you can cut it yourself using a sharp pair of scissors. Not all configurations are stock items. Contact us for availability. To order o-rings please refer to Enduro-Shield O-Rings, or Custom Gaskets.
