R43 Series small pressure regulator

The R43 is a cost-effective option for both general industrial and civilian markets. It employs a proven single-stage pressure reduction structure and weighs only 0.9kg, greatly facilitating mobile operations. The main body is made of high-quality brass, while the top cover is constructed from high-strength hard aluminum alloy with a chrome-plated finish, reducing weight and enhancing weather resistance. It is widely applicable to low-flow gas supplies in shops, homes, and factories. This product strictly adheres to UL safety standards, and the inlet pipe is equipped with a sintered bronze filter that effectively intercepts impurities in the gas source, protecting the internal precision valve seat from wear. Whether for oxygen and acetylene cutting and welding, or nitrogen purging, the R43's simple and reliable performance makes it a trustworthy gas control tool for everyday work.
