Guardian AP470-001 GS-Plus ABS Replacement Eyewash Spray Head

✅ Precision-Engineered For GS-Plus™: Designed as a drop-in replacement for compatible Guardian GS-Plus series stations, helping maintain proper alignment and performance.

✅ Pressure-Activated Flip-Top Cover: High-visibility orange nylon cover helps protect the spray head from industrial dust and debris and opens automatically when water flow begins.

✅ Consistent 1.6 GPM Flow: Built-in flow control delivers a soft, steady spray pattern across fluctuating pressures from 30–100 PSI, suitable for emergency eye flushing.

✅ Integrated 60 PPI Filtration: Pre-installed polyurethane foam filter helps trap pipe scale, sediment, and airborne contaminants before water reaches the user.

✅ Chemical-Resistant Polypropylene: Engineered for harsh environments, the durable polypropylene body resists many chemicals, cleaning agents, and routine impact in industrial settings.

✅ Ready-To-Install Assembly: Comes pre-assembled with the filter, flow control, and dust cover already installed — simply thread it onto your 1/4" NPT male outlet and test.

An emergency eyewash station is only as reliable as its spray heads — and worn, cracked, or clogged heads are a common reason a station may fail a routine flow check under ANSI Z358.1. The Guardian AP470-001 is the GS-Plus replacement spray head used on compatible Guardian wall-mounted, pedestal-mounted, deck-mounted, and recessed eyewash stations, as well as Guardian dual-purpose eyewash/drench hose units. It ships as a complete assembled head with the integrated flip-top dust cover, 60 PPI polyurethane filter, and 1.6 GPM flow control already installed and ready to thread into a 1/4" NPT outlet.

GS-Plus eyewash spray head repair part, complete with flip-top cover, 1/4" NPT female inlet, sold as each.

Note: The GS-Plus head is the smaller-diameter eyewash style. Before ordering, verify that your existing head is the GS-Plus and not the larger FS-Plus style (Guardian AP470-021) used on some eye/face wash stations.

Key Features

Complete, Pre-Assembled Head
The AP470-001 ships as a single drop-in unit with the dust cover and cap (Guardian AP470-002ORG-R), 60 PPI polyurethane filter (470-004R), and 1.6 GPM flow control (470-005R) already installed at the factory. There are no sub-assembly steps — thread it onto the existing 1/4" NPT male outlet and the station is ready for testing.

1.6 GPM Flow Control
Guardian's built-in flow control delivers a consistent 1.6 GPM per head, holding flow steady across a working pressure range of 30 to 100 PSI. The result is a soft, full spray pattern designed for emergency eye flushing while delivering enough volume to help flush contaminants effectively.

60 PPI Polyurethane Filter
A dense 60-pore-per-inch polyurethane filter (Guardian 470-004R) sits inside the head to help trap sediment, scale, and pipe debris before water reaches the user. Filtration matters in an emergency — the spray should help flush contaminants without adding pipe scale or debris to the affected area. The filter is available as a stand-alone replacement part but ships pre-installed in the complete AP470-001 head.

Integrated Flip-Top Dust Cover
The high-visibility orange nylon dust cover (Guardian AP470-002ORG-R) stays attached to the head between activations, helping protect the spray outlet from airborne dust and lint common in industrial environments. The flip-top design means it cannot be lost or left off — it pops open automatically when water flow begins.

Tough Polypropylene Construction
Guardian molds the spray head body from polypropylene plastic for chemical resistance and impact tolerance in industrial and lab environments where splashed chemicals, cleaning agents, and physical bumps are routine. The polymer body also helps avoid the corrosion issues that can occur with chrome-plated metal heads in caustic or humid settings.

Installation Guidance

The AP470-001 features a 1/4" NPT female inlet that threads directly onto the 1/4" NPT male fitting at each spray outlet on the eyewash bowl, pedestal, or drench hose unit. Use a wrench to snug the head to the existing fitting for a secure seal. Most Guardian GS-Plus eyewash stations use two spray heads; many facilities replace heads in pairs to help maintain a balanced and consistent spray pattern.

Per Guardian's parts documentation, if you ever need to remove and reinstall the internal flow control (470-005R), it must be inserted into the body concave end first to operate correctly. With the complete AP470-001 shipped pre-assembled, this is only relevant when individual components are replaced later.

After installation, activate the station and confirm a soft, full spray pattern from each head. ANSI Z358.1 requires emergency eyewash stations to be activated weekly to verify proper operation; a newly installed spray head should be tested as part of that next weekly check.

Frequently Asked Questions

Which Guardian stations is this spray head compatible with?
The Guardian AP470-001 fits GS-Plus series eyewash stations, eye/face wash stations, and dual-purpose eyewash/drench hose units, including the G1805, G1806, G1814, G1825, G1849, G1891, G1902, G1991, G5022, G5026, G5046, GBF1724, GBF1909, and GBF1994 and their variants. If you do not see your specific Guardian model number listed, contact EyewashDirect with the model number and we will confirm compatibility before you order.

Does this come fully assembled with the filter, flow control, and dust cover?
Yes. The AP470-001 is the complete assembled spray head with Guardian's flip-top dust cover (AP470-002ORG-R), 60 PPI polyurethane filter (470-004R), and 1.6 GPM flow control (470-005R) already installed at the factory. Each of those components is also available individually if only one piece needs replacement.

What is the flow rate and pressure range?
Each AP470-001 delivers 1.6 GPM through its internal flow control, holding flow steady across a working pressure range of 30 to 100 PSI. Most GS-Plus eyewash configurations run two heads, so a complete station delivers approximately 3.2 GPM combined.

What thread size and connection type does it have?
The AP470-001 has a 1/4" NPT female inlet that threads onto the existing 1/4" NPT male outlet on compatible Guardian GS-Plus stations. No adapter is required when replacing an existing AP470-001 with a new one.

Is this a genuine Guardian Equipment part?
Yes. AP470-001 is Guardian Equipment's own model number for the complete GS-Plus replacement spray head — it is the OEM part listed on Guardian's published parts diagrams, not a third-party generic substitute.

How often should I replace the spray head or filter?
The right replacement cadence depends on water quality, station usage, and how the station performs at the weekly activation test required by ANSI Z358.1. As a general rule, the polyurethane filter (470-004R) should be inspected during the weekly flush, and the complete head should be replaced when the spray pattern weakens, the body is cracked, or the dust cover is damaged.

Will this work on a Guardian eyewash/drench hose unit?
Yes. Guardian's G5022, G5026, and G5046 drench hose units are dual-purpose eyewash/drench hose stations that use the same GS-Plus spray heads as Guardian's fixed eyewash bowls. The AP470-001 is the correct replacement spray head for the eyewash function on these units.

Should I replace one spray head or both at the same time?
Most Guardian GS-Plus eyewash stations use two spray heads. If one head is worn, cracked, clogged, or producing an uneven spray pattern, many facilities replace both heads at the same time to help maintain balanced flow.

What color is the dust cover?
Orange is the standard high-visibility color on the AP470-001 and is identified as Guardian sub-component AP470-002ORG-R on the manufacturer's parts list. The bright orange improves visibility of the spray head in a low-light or panic situation.
