Pre-filter your wine and protect your equipment when using a pump, Xpress Bottle Filler, or Buon Vino filter. An in-line housing with a stainless steel mesh screen. This is not a polishing filter, merely a protection against picking up bits of wood, skins or remaining seeds that might potentially damage the diaphragms of the pump. Fits 1/2in I.D. tubing. Temperature rated to 160°F.
