The Applied Nylon Hose Couplings are designed for coupling blast hoses together or attaching the hose to the blast pot. The nylon couplings feature a lightweight and durable design and are ideal for any compressed air blasting application. Manufactured from injection moulded nylon, all couplings are identical, ensuring they accurately couple together every time. Pre installed, spring loaded safety lock pins automatically interlock with the mated couplings. Their internal raised thread design allows for quick installation and prevents the couplings from accidently slipping off.
