ABSTRACT:
A connector for joining small diameter fused silica tubing or fibers to similar or dissimilar materials that use an included taper angle of from 20.degree. to 40.degree. on a conical tapered section of a fused silica body to provide a reliable high temperature connection. The taper angle provides a compressive loading on the fused silica. The connection avoids tensile loads on the small diameter section of the fused silica. The tensile loads can cause cracking of the silica. The connection is lightweight and provides a tight seal at temperatures of 600.degree. C. or more. This connector is particularly suited for connecting capillary tubing to metallic tubing at high temperatures.
