The Applied metal hose couplings come are manufactured from robust, sand cast construction and can withstand the harsh working environments where there is the possibility of damage from other plant and machinery. Our couplings feature a simple locking mechanism that provides a secure join between the couplings. Raised internal rings prevent any air leakage and also increase the couplings gripping force on the blast hose. Our strict quality controls ensure that all couplings are of excellent quality with no flaws. Replacement gaskets are also available if required.
