Yale Figure 515 Flanged Closure

With over 65 years of manufacturing and reliable field service experience, our Yale closures have become the industry leader. With the original Figure 500 closure, Yale was first to develop the inherent safety and operating ease of a threaded closure.


Our Figure 515 flanged closure offers a bolted flange-to-flange configuration. A durable ACME thread fastens the cap to the hub, making our Figure 515 the safest in the industry. The pressure seal is achieved by an O-ring set in the face of the hub. Figure 515 closures are available in diameters from 2 to 42 in. and ANSI Class 150 through 1500.
