Overview

TUBE TURNS® manufactures Threaded closures in popular sizes ranging from 2" through 24" in ASME Pressure Class 150 through 900. Threaded closures in 26" through 42" are available in ASME Pressure Class 600.

Threaded closures are available in horizontal and vertical orientations. Threaded closures offer safety with a simple design that consists of only a head, welding hub, pressure warning device, integrated tool to assist in opening and closing the larger size closures and heavy-duty hinging hardware with adjustable davit mechanisms on larger sizes.

TUBE TURNS® Threaded Closures are manufactured utilizing the precision of CNC machining to provide accurate and consistent dimensions.

Threaded Closure Safety Features

Operational Assurance

To assure that the Threaded Closure will consistently open and close easily, TUBE TURNS® applies a Fluoropolymer coating on the ACME head and hub threads that provides corrosion resistance and solid film lubrication.

This coating, used in combination with appropriate lubricant on the threads, assures reliable closure operation. The Pressure Warning Device is manufactured from Stainless Steel to provide corrosion protection for this safety item.
