New OPW Twist-Lok dry disconnect couplings minimize fluid loss

July 19, 2017

OPW Engineered Systems, part of OPW's Fluid segment within Dover Corporation, now offers its new Twist-Lok dry disconnect coupler. With its user-friendly operation and simple handling, the new Twist-Lok provides a quick, easy connection with minimal product loss.

Representing the latest addition to OPW’s industry-leading range of dry disconnect couplings, the Twist-Lok has been specifically designed to be fully interchangeable with other dry disconnect couplers in the marketplace. 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 unique 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.
