Compatibility & Installation Notes

Match the inlet, operating-key series and required hose adapter. The domestic 5RC has NPT threads; 5RC-BSP is a distinct thread option. A garden hose does not screw directly into the valve opening.

Use the manufacturer’s 5-series pressure-loss curve to size the connection for actual demand. The wider family’s 10–125 GPM listing does not mean that every valve size delivers every flow with an acceptable pressure loss.

Isolate and depressurize the supply before installation or service. Provide stable support, accessible cover clearance and the backflow protection required by the system. Keys and hose accessories are separate selections.

Frequently Asked Questions

Which operating key fits the 5RC?

Use the matching Rain Bird 55K1 / 55K-1 operating key with the appropriate outlet threads and hose accessory.

Does the 5RC have a locking cover?

No. Its yellow cover is non-locking. Choose the 5LRC when the installation needs the corresponding yellow locking cover.

Is the 5RC inlet a hose thread?

No. The domestic model has a nominal 1-inch female NPT pipe inlet. The removable operating key provides the outlet connection.

Can I size it using the family’s 125 GPM maximum?

Use the model-specific 5-series pressure-loss table instead. Rain Bird lists 4.1 psi loss at 30 GPM and 11.0 psi at 50 GPM for that series, so available supply pressure matters.

Why Buy from Big Frog Supply?

The 5RC is a practical choice when you need the 55K1-series key connection, a one-piece body and a non-locking yellow cover on a 1-inch NPT supply. Its 5-1/2-inch height is shorter than the 6-inch 44-series body, and the published 5-series pressure-loss points let you compare hydraulic performance before choosing a valve.
