The PA Foam Lance is manufactured in Italy and is built to last. The foam lance body is made of solid brass, which ensures that is extremely strong and durable. Most of the internal components are also made of solid brass, with the rest comprising stainless steel and heavy duty nylon. With the exception of the Karcher (K) option, all of the fittings are made of either solid brass or stainless steel, and connect to the injector head either directly or via a short stainless steel extension pipe. The adjustable foaming tip is made of heavy duty nylon (as is the Karcher (K) fitting), while the generously-sized bottle is made from chemically-resistant high-density polyethylene (HDPE). The solid brass piston assembly offers highly flexible dilution rate adjustability via a large top-mounted control dial, which allows you to fine tune the thickness of foam produced (clockwise for thicker foam, anti-clockwise for thinner foam). You'll be amazed by the performance of the PA Foam Lance, and once you have adopted it into your wash routine you won't look back. Note that as long as you flush it out properly after each use (see the How To Use section) and don't damage the piston assembly (by forcibly turning the control dial beyond its stops), the PA Foam Lance should give you years of trouble-free use. However, it is worth stripping it down carefully and cleaning it out thoroughly on an annual basis.
