1/2-Inch Male-Thread Drip Line Flush Valve

This 1/2-inch male-thread drip line flush valve provides a flushing outlet at a matching female port. Its exposed male inlet thread distinguishes it from the female-thread and direct-tubing versions, helping you select the right connection for your line end.

Match the threaded port

• Listed inlet: 1/2-inch male thread.
• Mating connection: compatible female threaded port.
• Visible design: black threaded body and a ribbed blue outlet cap.

Confirm the female port size and thread standard before ordering. The nominal half-inch size alone does not prove that two threaded fittings will seal together. Check the complete connection rather than substituting a valve based only on the appearance of its cap.

Provide an accessible flush outlet

Leave enough clearance around the valve to inspect the outlet and attend to the cap. Plan where discharged water will go during maintenance. Support the surrounding line so bending loads do not bear on the threaded inlet.

Install with the line off

Depressurize the supply and remove dirt from the mating port. Check the threads for damage, then fit the valve using the sealing method required by the confirmed connection. Do not force crossed threads or overtighten the plastic body. Restore water gradually and inspect the joint.

Include the outlet in your routine flushing checks, particularly after repairs or new line installation. Use the operating instructions for your valve assembly. A pressure threshold or discharge volume specified for a different valve should not be assumed for this version.

Compare connection styles

For a male outlet, choose a female-thread flush valve with a matching thread. For a tubing end without a threaded adapter, compare the lock-connection drip line flush valve.
