Specifications and Benefits of the Flexitallic Spiral Wound Gaskets

Must read

The Flexitallic Spiral Wound Gaskets are designed for various industrial applications, including fluid sealing and vacuum sealing. They can be used in a number of different ways, from watertight to gas-tight. These reliable, flexible gaskets are made from advanced silicone rubber compounds with a sturdy aluminium coating that lasts 24x longer than the average spiral wound gasket.

Specifications of the Flexitallic Spiral Wound Gaskets

  • Range of sizes available: From 1” to 5” (25mm-127mm)    
  • Designs optimized for high vacuum or high-pressure applications
  • Excellent resistance against chemicals and oil 
  • Provides exceptional leak resistance without a vacuum test for up to 24x longer than the average spiral wound gasket

Applications of the Flexitallic Spiral Wound Gaskets

Vacuum and pressure seal: Vacuum tight, fluid-tight seal with a low-pressure differential between the seal and the sealing chamber. For example, in high vacuum applications where gas lifting is required but compressed air is restricted. Ideal for UPS applications where greater reliability and efficiency are required. 

Watertight: Watertight, forming a seal with a final inward force of 200 lbs/in.2 (17.74 kPa). A watertight seal is required for many applications where the primary concern is minimizing water leakage

Shear and compression resistance: Extremely high shear/compression resistance, tensile strength, and toughness; capable of withstanding extreme loads without distortion, or loss of vacuum or pressure. 

Temperature range: -40 to 250°F (-40 to 120°C) 

Operating speeds: From slow (0.15 in./min.) to high speed (0.5 in./min.); seal can be designed for high-temperature applications

Benefits of the Flexitallic Spiral Wound Gaskets

Reduced design time: fewer parts to calculate and procure.

Increased reliability: 24x longer than the industry average gasket.

Enhanced versatility: Available in sizes from 1” to 5” (25mm to 127mm) for a broad range of applications.

 Proven performance: Tensile strength and toughness, shear/compression resistance and chemical resistance enable the Flexitallic Spiral Wound Gasket to withstand extreme loads without distortion, or loss of vacuum or pressure.

How to choose the right Flexitallic spiral wound gasket?

When it comes to choosing the right Flexitallic Spiral Wound Gasket you need to be able to make a list of your specific needs and needs. Choosing one based on features means that you may have a lot of features, but ultimately are not as reliable or versatile as other models.

The following information should be taken into account when selecting the right spiral wound gasket. Most of this can be found on the website of the making, but also you will find out enough to make a decision.

Basic Dimensions: these are the first 3 measurements. The diameter of the product is measured in inches or millimetres. The length of a tube or a barrel can be measured in inches or millimetres, depending on the use and on the terms of reference used by the customer.

Welding Point: this is the point where 2 pieces would come together in a joint to make a single unit. Some gaskets have more than one welding point by joining several tubes together to get thicker walls.

Cutting Length: this indicates how much extra length you will need when cutting to fit your application. This is usually 1/2″ more than what you need for final assembly unless otherwise stated on a drawing from your supplier.
