|
|
SAS Industries, Inc.
carries an extensive range of standard tooling for Waveguide Gaskets.
These gaskets can be supplied either molded or die cut in a wide range
of compounds.
A few examples of various compounds used are Silicone, Neoprene,
EPDM, and EMI/RFI Shielding Materials for conductive applications.
Our standard Waveguide Gaskets are made to fit CPR, UG, and CMR flanges, and we can also produce any other form fo waveguide gasket to fit any other flange design. Our leading stance in this field enables us to stock a wide variety of Waveguide Gaskets giving us the ability to ship low or high quantities within days of receiving your order. We make our Waveguide Gaskets to nearly any compound, most commonly in a Grey Silicone to ZZ-R-765 CL2A/B GR70 or a Conductive Silicone variation (Typically SAS SEALTRON 1068, an 85 Durometer Silver Plated Copper filled Silicone that is tan in color. More information on the conductive silicone types of materials can be found by clicking here.
Below you will find some of our standard sized waveguides. Keep in mind we are capable of making many custom sizes along with having many more sizes that aren't listed. For example we have many hard to find PDR Style Waveguide Gaskets that are not yet listed here. |

| Waveguide Gasket Material Information |
|
|
While we have made waveguide gaskets in many different materials the following is a listing of the most common. If you would desire a different material please contact a sales representative and they will gladly assist you.
| Designation |
Description |
| SI70 |
SI70 is a 70A Durometer Silicone. This is a non conductive silicone. It is typically supplied in grey for "molded" parts and orange for "flat stamped" parts. It can however be supplied in either or. If color is important please specify. |
| 1056 |
1056 is SAS SEALTRON® 1056. This is a Silver Plated Aluminum filled Silicone, 65A Durometer. This is typically supplied in blue and is typically used for "flat stamped" parts, but can also be used for "molded parts" as well. This is a conductive silicone |
| 1068 |
1068 is SAS SEALTRON® 1068. This is a Silver Plated Copper filled Silicone, 85A Durometer. This is typically supplied in tan and is typically used for "molded" parts, but can also be used for "flat stamped" parts as well. |
| 1098 |
1098 is SAS SEALTRON® 1098. This is a Reinforced Silver Plated Copper filled Silicone. This is supplied tan in color with a Copper Reinforcement and is only used for "flat stamped" parts when a pressure seal of up to 20 psi is required. This is also only available in gaskets designed to .027" thick. |
