A compact sterilizable unit (10) has a control box (12) containing internal water and air supply networks (60, 40) and a sterilizable water supply bottle (58), dental handpiece (24), and dental syringe (100) removably connected to the control box (12) by means of specially adapted connector fittings (22, 62, 80). The unit (10) has a retrofit connection (20) to a conventional four hole connector which supplies operating air under pressure to the conventional dental operating foot control. Only sterile water is supplied to the patient from the sterile water bottle (58) through the handpiece (24) and syringe (100). The connection of the handpiece (24) to the control box (12) is through a high temperature resistant sterilizable tubing harness (202) having an expanded sheath construction that does not inhibit bending. Short, high temperature resistant tube sections (203) which are strengthened by an expanded shrink fit covering sheath (206) are disclosed. Special high temperature resistant tubing and seals are provided so that the entire unit (10) may be sterilized.
