High temperature gaskets come in a wide range of materials. High temperature scenarios need to be carefully examined in order to choose the best gasket maker. Any gasket selected has to be durable and safe to use and must create an effective thermal barrier for the application for which it is being used.
There are several materials used to create a high temp gasket, including ceramic, Kevlar, fiberglass, silica and silicone. Select the material based on the application, with the more complex, dangerous and high temperature situations requiring the best materials. As you consider which high temperature gasket material to choose, consider these:
1. Select a product based on its maximum temperature. For example, compare the rubber gasket maximum temperature per manufacturer before choosing.
2. Look for the best material based on the application of it, such as choosing a high temp gasket sealant or rolls.
3. Determine what the cured stage of the product is. For example, does it create a high temperature seal that is tough and still rubbery solid at room temperature?
Action Steps
The best contacts and resources to help you get it done
Use high temperature tape for a hi temp gasket used in thermal or electrical insulation situations
Tapes work in a number of scenarios including industrial, marine, automotive, welding and aerospace applications. They work to seal off ovens and furnace doors.
I recommend: Choose high temp gaskets in the form of tape for easy application, such as those offered by
Flextech Engineering, where a full line of sizes and types of tape are available. Specific applications for high temperature tapes are available through
Insulfex. These are available as glass fiber and silicone rubber tapes in adhesive and non-adhesive form.
A high temp silicone gasket protects from temperature extremes
Choose the right gasket maker of high temperature gasket products that meet the highs and lows in temperature for your application, especially those offering silicone based gaskets.
I recommend: Buy extruded silicone seals for your high temperature gasket needs. The silicone protects your device from deterioration from the ozone, weathering and the corona.
Gaskets Inc. provides a full line of extruded silicone products. Some silicone products handle temperature extremes ranging from 178 degrees F to more than 550 degrees F.
Tricomp offers silicone high temperature gaskets in a variety of sizes to fit these needs.
Customize the high temp gasket you need for your application
Look into companies that offer customization for gaskets. Some will come to your location and customize the high temp gasket to fit your specific application.
I recommend: Call on companies to come to your location to custom design the right high temperature gasket sheets or other products for your coolers, ovens or other commercial devices.
Inspector Gasket provides this customization service.
Gardico offers an extensive inventory of products, but also offers custom gaskets including a metal gasket for high temperatures.
Tips & Tactics
Helpful advice for making the most of this Guide
- Consider all the applications you have in high temperature gaskets. Ropes, tadpole seals, flexspans, ducting and expansion joints are just a few of the types of hi temp gaskets available on the market. Still, it is essential to consider the gasket required by manufacturers, especially when warranties are in place.
