◆ Nylon hose coupling:
DFBLAST nylon hose couplings are designed for coupling blast hoses together or attaching the hose to the blast pot. Manufactured from injection moulded fiber-reinforeced nylon. All couplings are identical, ensuring they accurately couple together every time. The special shape of the gasket extends the couplings durability. A built-in lock-spring on the coupling keeps the couplings securely connected.
Working temperature range: -40℃～+80℃

◆ Brass hose coupling:
DFBLAST brass hose couplings are designed for coupling blast hoses together, or to couple the blast hose the blast pot abrasive metering valve. Manufactured from tough corrosion resistant braze are preferred when longer lasting couplings. Will not rust when left outside for extended periods. Braze quick couplings with high impact on surfaces work and avoid changing out frequently in a harsh environment.

◆ Cast iron hose coupling
DFBLAST cast iron hose couplings are designed for coupling of blast hoses together, or to couple the blast hose to the blast pot abrasive metering valve.Manufactured from cast iron they are ideal for use in extremely harsh environments where there is the likehood of damage from other plant or machinery.The snap together design ensures quick, secure joining of mating couplings. Raised interal rings aid in preventing air leakage and increase hose to coupling gripping force.

◆ Aluminium hose coupling
DFBLAST aluminium hose couplings are designed for coupling blast hoses together or attaching the hose to the blast pot. Manufactured from tough, precision injection moulded aluminium are widely used for joining section of hose together. Aluminium quick couplings are lightweight and don’t bind to aluminium threaded nozzles and stand up to most weather conditions and daily use.
