The In-line Filter Trap removes moisture, oil, and dust from the gases before they flow into your instrument. It consists of a transparent acrylic tube containing a molecular sieve and a desiccant, Drierite. An indicator changes color to let you know when the packing must be changed, while the cartridge design makes replacement of the filter material easy. The 1/8 inch fitting on the trap allow you to insert the filter easily by attaching it to the 1/8 inch copper line. The filter can also be attached directly to the regulator, using a 1/4 inch to 1/8 inch Swagelok reducing fitting (P/N 09903471), which must be ordered separay. A refill kis also available.
