Claim:
1. A method comprising: heating a thick band to an assembly temperature; disposing the thick band about a circumference of a monolithic flat SiC plug head; and bringing the thick band and flat SiC plug head to a room temperature, wherein the assembly temperature is greater than an operating temperature and the room temperature is less than the operating temperature, wherein the thick band exerts a radial stress upon the flat SiC plug head at a room temperature and at an operating temperature, wherein the radial stress is between 10% and 40% of a residual stress of the flat SiC plug head wherein the radial stress is from between 800 psi and 8000 psi at the operating temperature, wherein the operating temperature is between 120° F. to 1000° F.
