Spiral EMC gaskets

Spiral Shield Gaskets

In order to compress the „Spira Shield“ gaskets by 25% of their diameter the following forces are required:

  • Standard Force: 30 pounds per linear inch of the gasket
  • Moderate Force: 10 pounds per linear inch of the gasket
  • Low Force: 2 pounds per linear inch of the gasket.

Spira Strip (Military Grade)

Spiral gasket with tin-plated beryllium copper and elastomer seal
Spira Strip is a Spira shield gasket to which a strip of solid or foamed elastomer has been attached. The elastomer is provided with adhesive tape to keep the spiral in the required position. Solid elastomers also serve as a mechanical stop to protect the spiral gasket from excessive compression as well as acting as a seal.
Foamed elastomers are preferred as environmental seals against rain, wind and dust.
Solid silicones have a Shore hardness of approx. 40°. They can be supplied as fluorosilicone if the „S“ from the order number is replaced by an „F“ (e. g. SS-0622/F).
Moderate Force und Low Force spirals have a solid elastomer core of approx. 80 Shore and a diameter some 75% of that of the spiral.
The Moderate Force spiral can also be ordered without the elastomer core by adding „NC“ to the order number (e.g. MS-0834 NC/S).
Foamed silicones are supplied with Shore hardness of 15°-25°. They can also be replaced by a neoprene foam if the „C“ is replaced by „A/P“ (e.g. MS-0623-A/P).

Basic Spira Multi-Seal


Wersja podstawowa spira MULTI-SEAL

These spiral seals have a specially formed elastomer seal for use with very uneven sealing surfaces. Their design allows the elastomer seal to act both as pressure stop to
protect the spiral shield gasket and also as a seal against dust and moisture.
