A thermostatic fluid valve of the type having a temperature responsive power element mounted between upper and lower housing members. A tubular extension member is attached to the lower end of the power element and permits a spring biased valve member to be mounted thereon. The tubular extension member has an inwardly extending flange formed on the upper end and is received over a cylindrically shaped, cold formed boss projecting from the lower end of the power element. The extension member is retained on the lower end of the power element by orbitally staking the boss radially outward to form a cold worked, high strength retaining flange. |
