The seals and coated metal parts on this sprayer have been chosen for their compatibility with the harshest of chemicals. Comes complete with viton seals. Kwazar Venus Super Compression Sprayer Pro features a 360 degree adjustable spray nozzle, helping you get in those hard-to-reach areas. The plastic tip of the Kwazar Venus Super Compression Sprayer Pro prevents degradation caused by any build up in the tip. This Kwazar HD Sprayer also has a stabilizing “apron” around the bottom of the bottle to ensure it won’t be knocked over easily.
