Hollow orings are used as sealing elements, as energizing elements
for hydraulic slipper seals and wipers and thus cover a large number
of fields of application. Hollow orings offer a low closure force
alternative to solid orings. As required for many lids and doors,
hollow orings are used in applications that require the seal to stay
in the groove while not overfilling the gland or warping the
enclosure lid or door. Hollow orings consist of an elastomer inner
ring and a seamless sheath which surrounds the elastomer ring.
Similar to PTFE orings hollow orings are used wherever the chemical
resistance of normal elastomer orings are not sufficient. The
required elasticity is provided by the elastomer ring, the chemical
resistance by the seamless sheath.
Hollow orings are chemical resistant, a wide range of thermal stability, low permeability and low friction. Hollow orings are especially useful for these applications. Enclosures that use flat-panel sealing are not typically fabricated with tight tolerances and are often made from thin metal or plastic. And large enclosures are more susceptible to leakage due to tolerance-gap runout along the sealing perimeter. Low closure force may also be desirable to decrease the loading on hinges and fasteners.
Encapsulated hollow seals consist of an elastomer inner ring and a seamless sheath which surrounds the elastomer ring. Similar to PTFE Orings encapsulated and hollow seals are used wherever the chemical resistance of normal elastomer Orings are not sufficient. The required elasticity is provided by the elastomer ring, the chemical resistance by the seamless sheath.
There are no fields of industry where hollow seals are not used. From an individual seal for repairs or maintenance to a quality assured application in aerospace, automotive, pharmaceuticals or general engineering. Darcoid Nor-Cal Seal is a world class supplier of hollow seals and other rubber, sealing elements.
