The ST-2300 is a professional high pressure cleaning gun (hot/cold water). The grip housing is from an impact-resistant plastic. The valve body and connectors are both corrosion-resistant. The trigger is equipped with a safety lock and rotating swivel joint that the high pressure hose cannot be turned so as to unscrew the connection between high pressure hose and spray gun a swivel joint may be used. By means of this swivel joint the gun may be turned slightly when in an unpressured state in relation to the hose. With increasing pressure the swivel joint becomes increasingly difficult to turn.

PMEG nozzles is high impact washJet flat spray nozzles are ideal for pressure washing, cleaning and car wash applications. Advantages of Power-MEG nozzles is: 3 time faster, saves up to 60% water, 3 times higher impact. Hardened stainless steel construction provides long wear life and flow control accuracy. Recommended for surface cleaner use. The WashJet product line, however, was designed specifically to operate in high-pressure applications and will provide improved cleaning effectiveness and a better distribution of impact across the entire spray pattern.
