Compatibility & Installation Notes

Check the 3/4-inch NPT supply connection and use the model-specific 33DK key. A 3K key is not the listed key for this valve. Select any hose swivel or outlet adapter to suit the key and watering equipment.

Follow the installation layout for a supported, accessible valve with drainage beneath it. Shut off and depressurize the supply before installation or service. The 3RC is the one-piece model; the 33DRC is a different, two-piece valve.

Frequently Asked Questions

Which key fits the 3RC?

Rain Bird specifies the 33DK key for the 3RC valve. The key is sold separately; 3K is not the listed key for this model.

What pipe connection does it have?

The 3RC has a 3/4-inch female NPT inlet. Match the supply fitting to this thread type and nominal size.

Is the 3RC a two-piece valve?

No. The 3RC has a one-piece body. Rain Bird lists the 33DRC as a separate two-piece model.

Why Buy from Big Frog Supply?

Select the 3RC when your access point calls for a one-piece brass valve on a 3/4-inch NPT connection. Its 4-1/4-inch height helps you plan the enclosure, while the separate 33DK key requirement helps you order the operating hardware that actually fits this valve.
