The Suttner ST-2000 Big Hand Gun is the strongest gun in its class, designed to take abuse and heat, making it perfect for rental machines or employees who are careless. This heavy duty gun has a unitized valve that is easy to access for repair. The stainless steel internal tubing, brass inlets, and outlets mean there is less corrosion and therefore, greater reliability. The forged brass housing provides maximum strength while the stainless steel spring, needle, ball, and seat are great for chemical resistance. Special heat and chemical resistant seals provide optimum performance even in harshest of environments. Great for up to 10 GPM, 5000 PSI, 300°F. It has a 3/8 FPT inlet and 1/4 FPT outlet.
