Quick Disconnects & Related Products

When ordering Parker quick couplers (QCs), please order coupler bodies and nipples separately. List the part number for coupler bodies and nipples as separate items rather than in combinations. Double check the thread and hose sizes of QCs prior to finalizing your order.

Many of Parker’s quick coupling products are available with unique non-standard options well suited to very specific applications. Examples of unusual applications include:
• High temperatures (above 250° F)
• Extremely caustic/corrosive solutions passing through the coupling
• External/environmental corrosive environment
• Other wear and tear situations such as dragging couplers along the ground
