Product variants

Spiraltherm Graphite 9584/GA
Spiral wound gasket with outer guide ring.
Standard type for raised face flange connections.

Spiraltherm Graphite 9584/GIA
Spiral wound gasket with inner and outer guide ring. This style offers the best performance for raised-face flange connections.
The inner ring is used to provide:
- Avoid over-compression at elevated seating loads in high pressure service
- Reduced turbulence within the flange area and protects against corrosion or erosion
- Improvement of the load distribution over the gasket

Spiraltherm Graphite S 9584/NF
Spiral wound gasket without guide or inner ring.
This style of gasket is used in load-bearing flange configurations, such as tongue and groove flanges.
Standard dimensions according to EN/ASME.
Spiraltherm Graphite 9584/VRI
Spiral wound gasket with inner ring.
Mainly used for male and female flanges or projection and recess flanges.
An inner ring is necessary as a compression stop.

Buralloy Heat exchanger seal 2500

The Buralloy heat exchanger seal 2500 is a semi-metal gasket with a soft core and metal jacketing. The Buralloy 2500 thus combines the benefits of a compressible soft seal with the mechanical strength of a metal seal. As a result, it can be produced in many different material combinations and in different styles to suit the application.

Buralloy Ring Type Joint 2961

Buralloy ring-type joint 2961 (RTJ) gaskets are manufactured from metallic materials in compliance with American standard ASME B 16.20 and the API specification. Detailed monitoring of every manufacturing step guarantees that the sealing rings offer the necessary surface hardness. This creates a functional seal without damage to the flanges. This gasket type is used successfully in downstream refinery applications, for example. RTJ gaskets are also commonly used in high-pressure valves and the associated pipe connections and in pressure vessel joints.
