All "Twist-Outs" are furnished in cast stainless steel CF-3M 316L ACI. 4" and 6" diameter openings available - coped to fit all size piping, tubes or tanks. Recommended for Maximum Working Pressure of 150# p.s.i. Available for vacuum service.

The Orbit "Twist-Out" is designed to make inspection and clean out of piping or tanks simple and quick. The Orbit "Twist-Out" eliminates the need for a pipe fitter to open a piping line or take off a flange for cleaning. The machine operator can simply open the piping line or tank without tools by twisting the "Twist-Out" handle and pulling out the inspection plug. The plug is fitted with an o-ring to allow for repeated access without replacing gaskets or seals.

Furnished from stock in 4" & 6" diameter sizes. "Twist-Outs" are supplied in standard pipe sizes or custom machined to meet your specific applications. The "Twist-Out" plug is designed to provide a smooth flow when installed in pipe lines.
