IB5000 / 74KB: RECTUS GmbH: Quick Coupling Division Europe

ISO 7241-1 Series B

Nominal Diameter
12.5/11 = 122 mm² / 95 mm²

TEMA Series RECTUS Series
IB5000 / 74KB

Flow Capacity Viscosity for 32cSt at 40°C as per ISO 7241/2-2006

Technical Description

The 74KB and IB5000 series plug profiles conform to ISO Standard 7241-1 series B and are compatible with other makes of the same standard. In order to give the best possible corrosion protection, the steel plug is passivated and sealed after galvanisation.

Advantages

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. Both series are equipped with double O-ring plus backup ring as standard.
