| Full Amazon title | Raincovo Chemical Injector Kit, 1/8 Inch 27 Male BSP Thread |
Straight from the Amazon listing's own attribute table. Fields the seller has clearly filled in wrong — a "hose length" of one inch on a brass fitting — are dropped rather than reprinted.
What ships in the box
Kit includes 2 pieces fittings, 2 pieces small balls, 2 pieces springs, 2 pieces o-rings outside and 2 pieces inside.
What Raincovo says it does
These are the manufacturer's own claims, quoted from the listing.
Chemical injector kit fits most pump which is an OEM brand. Replaces pump 203640GS 308452002, 190593GS and 190635GS.
Soap injector makes cleaning so much easier and faster. It’s a great replacement for the old rusted one.
The brass fitting is a 1/8 inch 27 male BSP thread. Install them and the soap dispenser works just like new.
How to install
Take the brass fitting, drop in the little ball, insert spring with small end against the ball, then attach it back on the pump. Do not over-tighten otherwise it will snap off.

How it connects
A downstream injector sits between the pump outlet and the high-pressure hose, so the chemical never passes through the pump. The matching 10-foot siphon hose is sold on its own: Siphon Hose for Downstream Injector, 10 ft.
Raincovo's listings do not name the pressure washer brands they fit — Ryobi, Sun Joe, Greenworks and the rest are not mentioned. What decides fit is the connector on your gun, wand or pump. The Raincovo Foam Cannon Parts, Bottles and Orifices guide goes through it.
