3/4-Inch Female-Thread Drip Flush Valve

A 3/4-inch female-thread drip flush valve provides a flushing outlet at a compatible threaded line end. The female inlet connects to a matching male fitting, while the blue cap makes the flushing end easy to identify during maintenance.

Match the female inlet

• Listed connection: 3/4-inch female thread.
• Location: compatible drip line flushing outlet.
• Visible design: black inlet body with a ribbed blue outlet cap.

Check both the size and thread standard of your male fitting. A nominal 3/4-inch dimension does not make pipe and hose threads interchangeable. Choose an adapter that matches the valve rather than forcing a connection that feels tight after only a partial turn.

Keep the flushing point accessible

Position the valve where its outlet can be inspected and discharge can be directed clear of equipment and walking routes. Leave room around the cap for maintenance. Support the mating pipe or adapter so its weight does not strain the threaded connection.

Fit and inspect the connection

Work with the supply off and the line depressurized. Clean the mating threads and check for cracks or damaged edges. Follow the sealing method appropriate to the confirmed thread type, and do not overtighten the plastic assembly. Restore the supply gradually and inspect the inlet joint and flushing outlet.

Check the flushing point during routine line maintenance and after work that could introduce dirt. Follow the operating instructions for your valve assembly rather than relying on a pressure setting from another flush valve.

Choose the correct connection version

Use this female-thread version for a matching male outlet. For a female port, compare the male-thread flush valve. For a direct tubing end, compare the drip line flush valve.
