Sealing Concept

The sealing principle of the Helicoflex® family of seals is based upon the plastic deformation of a jacket of greater ductility than the flange materials. This occurs between the sealing face of a flange and an elastic core composed of a close-wound helical spring.

The Delta® seal is a member of the Helicoflex family of spring energized seals. The sealing principle of the Helicoflex family of seals is based upon the plastic deformation of a jacket that has greater ductility than the flange materials.

Sealing Concept

O-Flex™ Metal O-Rings are designed to provide a sealing option for high pressure/temperature applications that require minimal spring back. The O-Flex™ is made from high strength metal tubing that is coiled, cut and welded to size.

O-FLEX™ Seals for Military Standards

O-Flex™ Metal O-Rings are designed to provide a sealing option for high pressure/temperature applications that require minimal spring back. The O-Flex™ is made from high strength metal tubing that is coiled, cut and welded to size.

Sealing Concept

The sealing concept of C-Flex™ metal C-rings is based on the elastic deformation of a metal “C” substrate which, during the
compression cycle, gives a contact point on each sealing surface.

The substrate characteristics determine the compressive load of the seal.

Sealing Concept

E-Flex™ Metal E-rings are designed to have low load, high spring back performance for high pressure/temperature applications. In service, the E-Flex™ is pressure energized by the system which increases the contact stress and further minimizes leakage.

Sealing Concept

Garlock Helicoflex is the world’s leading manufacturer of Nuclear Reactor Pressure Vessel (RPV) Closure Head Seals. In addition, Garlock Helicoflex sealing technology is used extensively as primary seals on spent fuel storage and transportation casks.

Sealing Concept

The Quick Disconnect System (QDS®) is designed to be assembled and disassembled quickly while offering space saving features. A typical QDS® requires less space than a traditional bolted assembly and can be easier to install, especially in tight locations where access to bolts and screws may be difficult.

Sealing Concept

The Helicoflex Boss Seal provides high performance sealing for standard boss fittings. The all metal construction is ideal for extreme temperature and pressure conditions and is qualified for space flight applications.
