Rain Bird RD12SP45F 12-Inch SAM 45 PSI Spray Body

Rain Bird RD12SP45F 12-Inch SAM 45 PSI Spray Body

Brand: Rain Bird | SKU: RD12SP45F

Product Overview

Supply a suitable rotary nozzle from a tall 12-inch pop-up body with Rain Bird RD12SP45F. Its built-in 45 psi regulator, SAM check valve and Flow-Shield combine pressure control, drainage protection and missing-nozzle service indication. This is the standard-cover version, and the nozzle is selected separately.

Key Features

• Triple-Blade Wiper Seal helps manage flushing and grit intrusion.
• Debris pockets help keep grit from recirculating inside the body.
• Reinforced ratchet ring supports nozzle-pattern alignment.
• Top-access internals simplify service.
• Built-in 45 psi pressure regulator.
• SAM check valve helps prevent low-head drainage across elevation changes up to 14 feet.
• Flow-Shield produces a low-flow service-indication stream when a nozzle is missing or damaged.

Common Uses

• rotary-nozzle zones requiring a 12-inch pop-up stroke.
• Replacing a matching RD1800 body after checking depth, inlet fit, pressure target and features.

Compatibility & Installation Notes

Allow space for the 16-inch body and 12-inch pop-up stroke. Install at the appropriate finished grade and connect through the 1/2-inch female NPT bottom inlet.

Check pressure with the zone operating. The supply must support the 45 psi target and combined nozzle demand; a regulator cannot boost low supply pressure.

Select a compatible Rain Bird spray-head nozzle and its required filter screen. Flush before nozzling, align the stem with the ratchet and follow the nozzle’s own pattern and radius instructions.

The SAM check valve limits drainage after shutdown; it does not close a leaking upstream control valve.

For flushing, the Flow-Shield instructions call for removing internals at lateral or branch ends, flushing until clear and reinstalling them. Install the appropriate nozzle filter screen for proper Flow-Shield operation. Its indication stream signals a service need; it is not a complete shutoff.

Choose a separately identified non-potable model when purple marking is required. RD12SP45F has the standard cover.

Frequently Asked Questions

Does it include a nozzle?

No. Select a compatible nozzle and its required screen separately for the intended watering pattern and zone flow.

How much installation depth does it need?

The body is 16 inches tall and the pop-up stroke is 12 inches. Check both the below-grade space and the clearance needed above grade.

Does this model include Flow-Shield?

Yes. A missing or damaged nozzle produces a low-flow service-indication stream. Flow-Shield does not shut off all water.

Can I connect it through a side inlet?

No. This SAM model requires its 1/2-inch female NPT bottom inlet.

Why Buy from Big Frog Supply?

Choose RD12SP45F for a standard-cover rotary-nozzle layout needing a 45 psi target and 12-inch clearance above grade. The 16-inch body requires more burial depth than shorter RD1800 models; its bottom-only SAM connection protects against low-head drainage across up to 14 feet of elevation head. Flow-Shield adds a visible service indication, while a separate NP model supplies purple identification when needed.
