Storz couplings (fire hose couplings)

Storz couplings are also often designated as fire brigade couplings. These are symmetrical, non-shut-off couplings. The couplings are connected by plugging the lug parts into each other and then twisted against each other. These can easily be coupled due to the rotatable lug parts and the seals are protected, as the seals must not be turned against each other. The couplings are often also designated as D-couplings (lug distance 31 mm), C-couplings (lug distance 66 mm), B-couplings (lug distance 89 mm) or A-couplings (lug distance 133 mm). Our aluminium couplings are, in contrast to many Asian products, forged and not cast, for strength reasons.
