Pressure Cap for Tank unit / adapter - Working pressure PN 10 bar / PN 25 barCan be used as a second orthird closing device accordingto ADR/ RID par 6.8.2.2.2The Mann Tek Pressure Cap for Tankunits / Adapters is designed to maximizeoperator safety and containment safety.Should the possibility of an upstream closureleakage occur, the Pressure Cap providesidentification of a system pressure andwill hold this pressure until the problem canbe safely resolved. Should the operator stillchoose to remove the cap it will reduce thestatic pressure to zero thus preventing theforceful expulsion of the transfer media.Working pressurePN 10 bar / PN 25 barFeaturesPressure indicatorDepressurizationCustoms / tamper seal featureAutomatic locking•Manually lockable (with padlock)Pressure Cap for Tank unit / adapter - How It WorksPressure Indicator(Warns for leakage inthe tank unit)Press (down)the handlePossibly pressure evacuated through avalve and the cap can be opened

Dust CapDust protection in rubberA Dust Cap gives very good protection againstcorrosion, and withstands both hot and coldenvironments.Dust Cap for increased safetyIt´s only possible to remove the cap from the Tankunit /Adapter after pulling the securing stift and atthe same time twisting the cap. The Dust Cap ismanually lockable with padlock.Standard Caps in Composite(Polyeten PE-HD 300).It covers the widest range of chemical and petroleumproducts.• Elastic v-ring seal in standard NBR thatmakes disassembly easier and seals ofa larger surface than conventional O-rings• Lockable and sealed• Patented designCaps are also available in Stainless Steeland Aluminium.
