3/8″ QC Plug x M22 15mm Male – Brass

The 24.5005 Brass Coupler allows quick connection between a 3/8″ quick connect (QC) plug and an M22 male fitting. It’s a go-to adapter for pressure washer setups where 15mm M22 fittings are common—especially on certain residential machines or European models.

Built from corrosion-resistant brass, it delivers leak-proof reliability under regular softwash or pressure washing use.
