Straight Through Quick Connect Air Couplings
Chasing max flow with less pressure drop? Straight-through quick connect couplers and nipples keep an open bore for pressure washers, steam cleaners and coolant or washdown lines. Choose brass for everyday corrosion resistance or 303 stainless for tougher environments. No auto shutoff, so stop flow and depressurize before you disconnect.
