The new Twist-Lok dry disconnect coupler (photo) 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 several 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-in. sizes (with larger sizes available upon request) and are available with a range of seal materials. The Twist-Lok is pressure-rated up to 360 psi, making it appropriate for high-pressure applications. It is also suitable for vacuum service. — OPW Engineered Systems, Inc., Lebanon, Ohio
