Resilient metal seal Parker Sealing and Shielding

Metal Seals/Resilient Metal Seals are designed for applications that require temperature and chemical resistance beyond that of even Parofluor Series elastomers. These seals are offered in many cross-sections, including "C," "U," "E," and "V," with spring-energized variations.

Parker S-Shape and Omega Metal Seals are high performance, resilient metal seals intended for separable joint type applications requiring
resistance to temperature and pressure extremes, resistance to corrosive fluids, zero leakage and exceptionally long life.
The Parker S-Shape Metal Seal features low seating load, high resilience. They are self energizing and pressure assisted. Parker S-Shape Metal Seals are reusable and require a very simple cavity design.

The high strength base metal "spring" is coated with a softer sealing material. When compressed between flat surfaces, the spring seal forces the soft coating material into the mating surface roughness, blocking all potential leak paths. Once initiated, the intimate contact is maintained by the seal's resilience, overcoming the effects of temperature, pressure, flange separation and reduction of bolt torque.

The Parker O-Seal Division also produces two additional types of resilient metal seals for use in super-critical sealing of nuclear, aerospace and aircraft engine applications. Both the Parker Mark I and Mark II Metal Seals are available in a wide range of base metals and surface coatings from PTFE to gold plating. For "zero leakage" applications, the Parker Mark I is
recommended and is available in either internal or external pressure versions, depending upon customer requirements.

The cavity for a Parker SShape Metal Seal must provide controlled squeeze, seal location, adequate sealing surface and structural support.

Parker S-Shape Metal Seals are recommended for use in applications beyond the limits of elastomeric O-ring seals. Typical applications for the Parker S-Seal include jet engine fuel and exhaust seals, nuclear couplings, cryogenics, bakeable vacuu hardware, steam systems, turbine engines, cylinder heads and plastics processing equipment.
