    Inadvertently unpressed connections are noticed immediately during a leakage test.
    Viega guarantees the detection of unpressed connections in the following pressure ranges:
    min. water pressure: 0.1 MPa / 1 bar / 14.5 PSI
    max. water pressure: 0.65 MPa / 6.5 bar / 94.3 PSI
    min. air pressure: 22 hPa / 22 mbar / 0.3 PSI
    max. air pressure: 0.3 MPa / 3 bar / 43.5 PSI

    Sealing elements
    EPDM (ethylene propylene diene rubber), black, pre-​assembled

    d12–108.0, size availability in accordance with the national regulations

    The functional safety of Viega press connector systems depends primarily on the faultless condition of the press tools used. For the manufacture of press connections, Viega recommends the use of Viega press tools. Viega press tools have to be regularly maintained by authorised service partners.

    Areas of application
    Closed cooling and heating systems
    Industrial and plant engineering
    Sprinkler systems (hot dip galvanised pipe)
    Compressed air systems (hot dip galvanised pipe)
    Solar installations with flat collectors
    Solar installations with vacuum collectors (only with FKM sealing element)

    Use of the system for areas of application and media other than those described must be agreed in consultation with Viega! Detailed information about applications, restrictions and national standards and directives can be found in the product information, either printed or on the Viega website.

    Note – Standards and approvals

    For use in heating systems, observe VDI Regulation 2035 and DIN EN 12828.

    Operating conditions with EPDM sealing element
    operating temperature max. 110 °C / 230 °F
    operating pressure max. 1.6 MPa (PN16) / 16 bar / 232 PSI

    Material press connector
    Steel 1.0308

    Note – Storage and transport
    To ensure the impeccable quality of Prestabo pipes, observe the following points during transport and storage:
    Packing and protective foil (on with PP coated pipes) should not be removed until immediately before use.
    The pipe ends must be closed with protective caps when delivered.
    Do not store the pipes directly on the bare floor.
    Do not stick any protective foils or plastics to the pipe surfaces.
    When loading and unloading, do not pull the pipes over the truck sill.

    Note – Protection against external corrosion
    Prestabo pipes and press connectors are protected by external galvanisation.
    In case of contact with dampness (condensation, precipitation during the construction phase, plaster and splash water etc.) or corrosive building materials (surfacer, levelling screed etc.), however this layer of zinc cannot provide permanent protection against external corrosion. the following protective measures are recommended:
    Use of closed-​cell insulating tubes with professional sealing of all abutting and cut edges using a suitable filler.
    Damp-​proofing of the laid pipe through separating foil in the floor construction.
    Installing pipes outside areas at risk of moisture.
    Visible radiator connections rising from the floors should be avoided if floors will be frequently cleaned with water and/or cleaning agents/disinfectants, for example in retirement homes and care facilities, as well as hospitals. Wall connections make cleaning easier and also exclude any additional risk of corrosion.
    If the radiator connections do come from the floor, professional corrosion protection and professional sealing of the joints are ensured. If not, there is a possibility that the cleaning water will penetrate, which will moisten the insulation and present the risk of corrosion.
    If the measures in the examples above fail to provide permanent protection against dampness or the areas of use have to meet special requirements, e.g. in cooling circuits, complete external corrosion protection, which reliably prevents influences that lead to corrosion, must be applied.
