Selection checklist
Confirm nominal size, flow demand, operating pressure, fluid medium, tube routing, available installation space, and expected mating cycles before final model selection.
Technical Resources
Practical notes for quick disconnect selection
Use these references to prepare a clearer inquiry. Final dimensions, drawings, and operating limits should be confirmed for each project.
Material options
Common body material options include 304 stainless steel, 316L stainless steel, and AL6061 aluminum alloy depending on series and application conditions.
Fluid compatibility
Typical compatible fluids include deionized water, purified water, ethylene glycol, and propylene glycol. Always confirm final compatibility by application.
Replacement caution
Interchange with other brands should be validated before use. A drawing, model number, and operating conditions are important for replacement checks.
Seal Material Guide
Start with seal compatibility, then confirm by application.
Seal choice depends on fluid, concentration, temperature, and service conditions. The table below is a reference, not a universal compatibility guarantee.
| Material | Temperature | Typical fit |
|---|---|---|
| EPDM | -40°C to 120°C | Standard choice for deionized water, purified water, and water-glycol systems. |
| FVMQ | -55°C to 155°C | Optional low-temperature seal for water-glycol systems and selected oils. |
| HNBR | -40°C to 150°C | Useful reference for oils, fluorinated fluids, and applications that need extra review. |
Usage precautions
Keep plug and socket mating surfaces clean before connection.
Use clean, filtered fluids within the confirmed compatibility range.
Do not exceed the specified working pressure or temperature range.
Align plug and socket during connection and disconnection.
Avoid impact damage, excessive hose bending, and incorrect installation torque.
Validate interchange with other brands before replacement use.
