These were designed for washing cars.\u003c\/p\u003e\u003cp\u003eThe body is precision-machined from a single piece of \u003cstrong\u003emarine-grade T304 stainless steel\u003c\/strong\u003e, with the orifice size and spray angle marked large enough to read at arm's length. T304 is the austenitic grade specified where salt and constant wetting are a given — the chromium content forms a self-repairing passive oxide layer, which is why it holds up in a wash bay far better than the plated brass most tips use.\u003c\/p\u003e\u003cp\u003eAround it sits a textured rubber shroud: it gives you grip with wet, soapy hands, and if a nozzle ever comes loose mid-wash it puts rubber rather than bare metal near your paint.\u003c\/p\u003e\u003ch3\u003eWhy 40°\u003c\/h3\u003e\u003cp\u003eA 40° fan is the wide, gentle pattern used for rinsing panels and paintwork. It spreads the same flow across a larger area, so the force landing on any one point is lower than a narrow 15° or 25° tip — the right trade-off when what you're rinsing is clear coat rather than a driveway.\u003c\/p\u003e\u003ch3\u003eWhich size do I need?\u003c\/h3\u003e\u003cp\u003eMatch the nozzle to \u003cem\u003eyour machine's flow rate\u003c\/em\u003e, not its pressure rating. Too small and you push the pump above what it's rated for; too large and you lose pressure at the tip.
