Specification :

DFBLAST hose couplings are designed for coupling blast hoses together or attaching the hose to the blast pot. 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.
