This range of dry disconnect couplings, named Twist-Lok, has been specifically designed to be fully interchangeable with other dry disconnect couplers. The Twist-Lok has also been manufactured in accordance with the Nato Stanag 3756 standard, and features 316 stainless-steel construction and an integral heavy-duty swivel to aid connection and minimize hose wear. In addition, this new coupler is designed with safety features for the operator, such as the ability to be fully interlocked when connected, while it includes a locking mechanism in the open position. Product selectivity is also available via mechanical keying to minimize risk of cross contamination.
Twist-Lok couplers are offered in 1-, 2-, 3- and 4-inch sizes (with larger sizes available upon request) and are available with a range of seal materials, including fluorocarbon, EPDM and FFKM with FNPT and ANSI flanged connections. The Twist-Lok is available with pressure ratings up to 360 psi, making it ideal for LPG and other high-pressure applications. It is also suitable for vacuum service, and meets or exceeds all European and American railcar approvals.
