The 72KB and IB2500 series plug profiles conform to ISO Standard 7241-1 series B and are compatible with other makes of the same standard. In order to achieve the best possible corrosion protection, the steel plug is passivated and sealed after galvanisation.

The pressure eliminator allows for coupling under static and residual pressure, up to operating pressure. It is available in the IB series in couplings and plugs.

See chart.
