Atlantic Gasket Adds Additional AMS & MIL Spec Silicones & Fluorosilicones

Atlantic Gasket is adding additional silicone and fluorosilicone rubber products to its material portfolio! The silicone rubbers added to our website will meet requirements specified by the Society of Automotive Engineers (SAE) and meet various AMS (Aerospace Material Specification) specs. These include AMS 3301, AMS 3302, AMS 3303, AMS 3304, AMS 3304, AMS 3305, AMS 3195, AMS 3196, AMS 3315, AMS 3320, AMS 3345, AMS 3347, AMS 3348, and AMS 3349. The silicone rubbers have the ability to resist a range of ambient conditions such as weathering, petroleum-based lubricating oils, extreme temperatures, and more.

Additionally, Atlantic Gasket is also adding multiple fluorosilicone rubber products as well, and these rubbers meet the MIL-DTL-25988C specification for various types and grades. These include Type 1 and 2 along with Grade 40, 50, 60, 70, and 80. The MIL-DTL-25988C specification refers to a range of fluorosilicone products like o-rings, compression seals, molded parts, extruded shapes, sheets, and strips.

Furthermore, Atlantic Gasket has also added a few other products such as AG-3686 low outgas/low temperature silicone specializing in spacecraft applications, AG-613-55LT conductive silicone that meets ASTM E595 low outgassing requirements and withstands extremely low temperatures, and AG21431 premium grade Viton™ that meets the Viton™ GF specification. Just like all of our sponges, rubbers, plastics, and other materials, these added rubbers will be available in custom-cut parts, sheets, rolls, and a variety of thicknesses.

Atlantic Gasket has the ability to die-cut, waterjet-cut, and knife-cut any of these new products to your custom-cut need for parts. We also provide laminating and slitting services to apply adhesive to materials and parts along with cutting them to custom stripping sizes. We look forward to helping you out with your next project!

You Need Holes? We’ve Got ‘Em!

Circle with Many Holes 8

We’ve cut several of these gaskets out of 1/8” thick 55 durometer Viton on our water jet machine.  What was the catch?  We had to put 242 holes and ovals into this 14 ¼” diameter piece.

However, it was no issue for our water jet machine and production line!  Our water jet machine can hold tight tolerances and cut a nearly infinite amount of different cutout dimensions and shapes.

If you have any project, regardless of how complicated you think it may be, give Atlantic Gasket a call at 800-229-8881 or 215-533-6400 and ask to speak to a member of our sales team or email us at sales@atlanticgasket.com.

Laboratory Gaskets

We recently received a request from a customer who required a chemically resistant gasket for a laboratory ventilation system and they presented us with a list of thirteen chemicals that this gasket would need to seal at temperatures up to 250 F.  Upon first review we thought that Viton (Fluoroelastomer) would be the ideal material.  However, in analyzing the list of chemicals we realized that Viton was not compatible with oxygenated ketones, one of Viton’s few weaknesses.  We then started to investigate using PTFE (Teflon) but quickly realized that the PTFE would not hold up against acetates at 250 F.

The next material that we investigated was flexible graphite.   We determined that graphite was the best material for this application and would perform well as a gasket in sealing our customer’s list of chemicals.  This material was readily available and we were able to ship parts the next day allowing our customer to meet his tight schedule.

We love being challenged, so please contact us with your design specifications and we will work to find a timely and economical solution.
