The Multi-Link integrated quick connect couplings come in units of 1 to 4 outlets. The units can also easily be connected to create more access points. Ideal for un-cluttering existing work areas or to create new flexible work stations. The integrated couplings provide flexibility and high performance, the design allows for a large number of outlets without restricting the flow with T-connections, bends or elbows. Combine with our high quality polyurethane hose to create a flexible high performance air distribution system.
