Metal Gaskets

Home  /  Our Products  /  Machined Components
Metal Gaskets are used for sealing higher temperature and pressure applications, where non-asbestos materials will fail. Typical applications are for heat exchangers, compressors, condensers, pumps, and valves.
Metal gaskets is a term often used to describe any size of gasket, shim or washer that is manufactured from elemental metals or alloys such as steel, brass or titanium. Specialist metal alloys such as Inconel, which is composed of nickel, chromium and iron, have properties suited to processes that undergo extreme pressures or temperatures.

Features
  •  Precision manufactured gasket to ensure best performance
  •  Silver-plated female threads
  •  Sizes range from 1/16" to 1" and 6 mm to 18 mm
  •  Test port at nut for easy leak testing
  •  All seal faces and male threads protected with plastic caps
  •  Every gland and body marked with size, material and heat number
Advantages
  •  Excellent resilience and recovery under fluctuating loads.
  •  Good for a wide range of temperatures and pressures.
  •  Compensates for minor flange irregularities.
  •  Available in various material combinations for chemical compatibility.
  •  Extremely robust and reliable for high-pressure and high-temperature applications.
  •  Self-energizing under internal pressure (BX/RX types).
  •  Offers good resilience due to the soft core.
  •  Protects the filler from corrosive media.
Why Metal Gaskets ?
High-Temperature Resistance
Unlike elastomers or fiber-based gaskets that degrade under extreme heat,

High-Pressure Capability
Metal gaskets can withstand immense pressures, making them ideal for high-pressure pipelines, valves, and vessels where leak prevention is paramount.

Chemical Compatibility
Specific metal alloys offer excellent resistance to a wide range of corrosive chemicals, acids, and alkalis, preventing degradation and maintaining seal integrity in aggressive media.

Durability and Longevity
Their inherent strength and resistance to creep and relaxation ensure a long service life, reducing maintenance downtime and associated costs.
Types of Metal Gaskets
Spiral Wound Gaskets (SWG)
Spiral Wound Gaskets are arguably the most common type of metal gasket for general industrial use.

Ring Type Joint (RTJ) Gaskets
Ring gaskets are solid metal rings with a specific cross-sectional shape (oval or octagonal) designed to fit into corresponding grooves in RTJ flanges.

Metal Jacketed Gaskets
Metal Jacketed gaskets consist of a soft filler material (e.g., mica, PTFE, asbestos-free fibers) completely enclosed or “jacketed” by a thin metallic outer layer.

Solid Metal Gaskets (Flat Metal Gaskets)
As the name suggests, these are solid pieces of metal, precisely machined to the desired shape and thickness. They rely on the uniform compression of the metal against the flange faces to create a seal.
