The Figure 500 closure design combines simplicity and reliability through the use of a rugged, modified ACME thread to fasten the cap to the hub. The pressure seal is achieved by an O-ring set in the face of the hub. Figure 500 closures are manufactured in sizes 2"-14".

The Figure 500R™ was designed for larger diameter closure applications, 16" and above. Figure 500R closures are machined with a bevel seat. The bevel seat on the hub provides the operator an accurate stabbing section and reduces the risk for thread and seal damage. Closure horizontal hinges swing left or right for sizes 16" and above.

The Figure 515™ flanged closure offers a bolted flange-to-flange configuration. A rugged ACME thread fastens the cap to the hub, making the 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 diameter from 2"-72" and ANSI class 150 through 2500.
