Can the STORZ fireman's cap with drain valve without chain, aluminum be used with couplings of different spacing and still maintain a secure seal at 16 bar?

No . the STORZ fireman's cap with drain valve without chain, aluminum cannot reliably be used with couplings of different spacing and still guarantee a secure seal at 16 bar. Opis wskazuje, Å¼e element ma symetryczny ksztaÅt ÅÄcznika i Åatwo ÅÄczy siÄ âz kaÅ¼dym innymâ, jednak jednoczeÅnie stwierdza, Å¼e elementy z tym samym rozstawem sprzÄgÃ³w moÅ¼na ÅÄczyÄ. To oznacza, Å¼e poprawne i szczelne poÅÄczenie zaleÅ¼y od zgodnego rozstawu i wymiarÃ³w sprzÄgÃ³w. Przy pracy pod ciÅnieniem do 16 bar szczelnoÅÄ zapewnia prawidÅowe dopasowanie mechaniczne i uszczelka z biaÅej gumy NBR . uÅ¼ycie sprzÄgÃ³w o innym rozstawie zwiÄksza ryzyko nieszczelnoÅci, uszkodzenia uszczelki lub mechaniczne odksztaÅcenie elementu, co moÅ¼e doprowadziÄ do utraty ciÅnienia lub awarii. Aby utrzymaÄ pewne, szczelne poÅÄczenie przy 16 bar, stosuj tylko elementy o zgodnym rozstawie sprzÄgÃ³w lub zastosuj odpowiednie adaptery zatwierdzone przez producenta.

Is the STORZ fireman's cap with drain valve without chain, aluminum compatible with different coupling spacings?

Yes. The STORZ fireman's cap with drain valve without chain, aluminum is compatible only with couplings that have the same Storz coupling spacing (symmetrical design). It easily connects with matching Storz elements; different coupling spacings are not compatible. Material: aluminum, working pressure 16 bar, seal: white NBR rubber.

Does the STORZ fireman's cap with drain valve without chain, aluminum require adapter rings for non-standard coupling spacings?

No. The STORZ fireman's cap with drain valve without chain, aluminum does not require adapter rings for non-standard coupling spacings because Storz couplings use a symmetrical, non-gendered connection design: elements with the same coupling spacing mate directly. Therefore as long as the mating part has the same coupling spacing, the cap will connect without adapters. If the other component has a different (non-matching) coupling spacing, an adapter ring or a properly sized adapter coupling would be needed to bridge the difference.
