When it comes to looking for best gasket selection for high temperatures, then things can get a bit heated. The main thing that matters is, each individual has its own conception of defining high-temperature gasket no matter for which terms and aspect they need it.

However, being an expert industrialist, it’s imperative to learn why you should use high-temperature gaskets, or how it could make your money worth investing in your new project. Let’s jump down!

What are high-temperature gaskets?

The high-temperature gaskets help prevent leakage of fluids and gas by providing an airtight seal between gaps in machine parts whose temperature may exceed 500-degree Fahrenheit.

The high-temperature gasket includes the following material;

  • Non-Asbestos Fiber Jointing
  • Ceramic Fiber (such as Firefly)
  • Nitrile Rubber
  • Silicone Rubber
  • Blended PTFE gaskets
  • Tang Graphite (with and without steel inserts)

Applications & uses

The high-temperature gaskets are used in;

  • Airframes
  • Appliances
  • Business machines
  • Compressors
  • Elevators
  • Plumbing system

And, it is used in a host of other varieties of equipment which require the use of gaskets in order to function safely and effectively.

The seals between joints are critical in many hydraulic, pneumatic, and aerospace applications responsible for maintaining air or fluid pressure in commercial aircraft for example gaskets throughout the aircraft keeps the cabin from deep pressurizing

Types of high-temperature gasket materials

There are many different types of high-temperature gasket materials available for various applications, the selected ones are mentioned below;

Style 9800 High Heat Gasket

This type of gasket material consists of carbon fibers with an SBR binder. This gasket is highly suitable to use with inert gases, water, mild acids, saturated steam, and mild alkalis.

The Style 9800 high-temperature gasket can persevere at temperatures of 73°c to +482°c (nonstop max 343°c) and up to 2000 PSI.


Style 9850 High-Temperature Gasket

This gasket contains carbon fibers with a nitrile binder. This one is best to use for ANSI-flanged connectors and turbine hybrid funneling connectors. It is also used in chemical processing, power generation, and hydrocarbon processing industries.

This specific style of warmth safe gasket is appropriate to be utilized with immersed steam, oils, gas, water, aliphatic hydrocarbons and generally refrigerants. Like the Style 9800, the Style 9850 high-temperature gasket can likewise withstand temperatures of 73°c to +482°c (persistent max 343°c) and up to 2000 PSI.


Style 9900 Heat Resistant Gasket

This style gasket is obtained by using graphite fibers with a nitrile binder. It is best to use for ANSI- flanged connectors and turbine hybrid channeling connectors.

This style of the gasket is frequently utilized as a part of energy age, synthetic preparing and hydrocarbon handling enterprises.

Reasons to use High-temperature Gaskets

Those applications which produce heat and temperature are considered high-temperature gasket applications. Though the techniques for manufacturing high-temperature gaskets have been changed from the past few years, yet in many businesses, Henning Gasket & seals stay on the top of cutting-edge technologies.

Common high-temperature applications include:

  • Heat exchangers
  • Steam lines
  • High-pressure pumps
  • Chemical reactors

The high-quality temperature gaskets are fabricated using precision cutting and stay same for tooling. You can conveniently get this material in a large variety, and can also get a quick turnaround on your order, usually within a day.

High-Temperature Gasket material is demanded those applications which require consistent exceeding of temperature around +750F.  The applications include; high pressure, intense heat, and saturated steam or hot oils which can immediately result in gasket failure – in case of taking wrong material for designing.

The highest limit of temperature for most commercially available “rubber” products is less than 500°F (204 – 260°C); silicone elastic naturally has the best temperature dependability of these. The average working temperature for silicone ranges from 400 – 500°F (204 – 260°C) with an erratic temperature up to 600°F (333°C).

Whereas, other materials including; EPDM, fluorosilicone, and fluorocarbon have an excellent heat resistance. It means the gasket material is able to retain its mechanical properties and will keep on performing a without reversion.
