Abstract:
A tube includes a casing made of a fluororesin. The casing surrounds a fluid tube and lid members, each made of a fluororesin and include a receiving portion for receiving one end portion of the tube. At least one sealing face is disposed in the receiving portion. Union nuts, made of a fluororesin, are fitted onto the end portion of the tube and screwed to one end portion of one of the lid members. A sealing portion is formed by fastening the union nuts to the end portions of the lid members to press the tube from the outside of the tube. A device element such as a filter member is placed in the casing.
