Guardian AP470-120R Spray Head Assembly

The Guardian AP470-120R is a replacement spray head assembly designed for GS-Plus series emergency eyewash and shower equipment. It fits compatible units identified by manufacturer part numbers G1724 and G1724P. This transparent component restores proper water flow and spray pattern for safety stations. Facilities maintaining Guardian safety fixtures use this part to keep equipment compliant and operational.

Brass construction with GS-Plus compatibility

The spray head yoke is manufactured from brass for durability in plumbing environments. It connects to existing Guardian GS-Plus hardware using the standard interface defined by the series design. Compatible Grainger part references include 3RVR4 and 3RVR5 for cross-referencing. No alternative series or brand connections are supported by this specific assembly.

Direct replacement installation

Installation involves removing the old spray head and threading the AP470-120R onto the existing yoke connection. The transparent finish allows visual confirmation of flow and debris. A common issue is mineral buildup on the old threads, which can prevent a watertight seal if not cleaned thoroughly. Ensure the inlet supply is shut off before starting work.
