Drylok™ Dry Disconnect Coupler & Adaptor
Drylok® dry disconnect couplers and adaptors are designed to safely transfer hazardous, corrosive volatile liquids such as acids, solvents and petrochemicals. Rugged design, excellent flow with little product loss makes the Drylok ideal for the most challenging loading-rack environments. The Drylok has become the coupler of choice in many of the most critical loading applications.
Features & Benefits
- Very low product loss. Flat Poppet Face design ensures minimal loss at disconnect.
- Fully interlocked. Double Safety System. Cannot be opened unless connected to mating fitting.
- Optimal flow. Less obstructions provide better flow characteristics in high-pressure or viscosity applications.
- Rugged. Designed to withstand everyday use/abuse at the loading rack.
- Ease of maintenance. Standard o-ring seals make maintenance simple, easy, and cost-effective.
- 150 psi (10 bar) pressure rating
- 1", 2" and 3" sizes
- Stainless-Steel, Alloy 20 OR Hastelloy C construction
- AAR approved
- CRN approved
- Can be coupled in any orientation - 360°

How to Rebuild a 2" or 3" Drylok™ Dry Disconnect
Success Story: SI Group
This success story demonstrates how the SI Group Manufacturing prefers OPW Engineered System's Drylock Disconnect Couplers and Adaptors for their outstanding safety features, with virtually no fluid loss and no exposure.
Drylok™ is designed to safely transfer hazardous corrosive, volatile liquids such as acids, solvents and petrochemicals. An interlocking handle averts accidental spills by preventing uncoupling while the valve is open. And, the unit's flat face minimizes fluid loss, further reducing exposure to risk during operation. Drylok™ is ideal for all kinds of hazardous fluids where product loss is a problem, such as high-pressure lines, high flow rates, slurries, and gases.
