Drylok™ Dry Disconnect Couplers & Adaptors
OPW Autolok® quick disconnects are self-locking couplers that provide an added level of safety and convenience at the fluid connection. Autolok’s® patented locking mechanism, built into the coupling arm, means you simply snap the locking arms shut with one smooth motion and the coupler stays secure and shut until you unlock it. No clips, pins or buttons. Autolok® uses the patented Twin-Kam™ feature to hold the adaptor more securely to the coupler to provide added protection against accidental release.
Features & Benefits
- Available in 1”, 2” and 3” sizes
- Standard O-ring seals for longevity, low cost and ease of maintenance
- Super-Pak Adjustable packing with V-type material provides a continuous compression, emission-free seal on handle shaft (2”& 3” only).
- Available in 316 Stainless Steel, Alloy 20, Hastelloy C with NPT, BSP, ANSI Flanged, BW and SW end connections
- AAR Approved
- CRN Approved
- One of the driest disconnects in the industry – less than 1/2 ml of fluid loss from a 2” unit (less than .10 teaspoon).
- Unprecedented safety – meets or exceeds all of today’s stringent emission and worker safety requirements set by EPA, OSHA, and others. Drylok™ cannot be uncoupled while the valve is open.
- Optimum flow rate – less obstruction in easy-flow interior optimizes the flow rate in high-pressure or high-viscosity applications.
- Ease of use – simple handle action connects valve to coupler and opens and closes the flow.
- 360 degree orientation ensures proper seating and alignment.
