Abstract

A capillary tube can be provided with a uniform internal elastomeric lining as follows. An elastomeric tubing having a uniform wall thickness and an outside diameter of from 0 to 0.001 inch greater than the inside diameter of the capillary tube is selected. The tubing is stretched and pulled through the crystal. When the tension is released, the tubing expands to form a tight seal with the capillary wall. If desired, the open ends of the capillary elastomeric lining can be sealed with pins and the structure encapsulated with elastomeric material providing, on withdrawal of the pins, a completely elastomeric encapsulated and lined capillary tube. The tube could be a tubular transducer useful for ink jet ejection.
