Elkhart Brass HF-500 Hydro-Foam Self-Educting Foam Nozzle
Description
Foam from a nozzle with no separate proportioner
The Elkhart Brass HF-500 Hydro-Foam is a self-educting foam nozzle: it draws foam concentrate in through a pick-up hose and a built-in metering device and discharges foam solution, so no separate foam mixing equipment is needed for a mobile or monitor-mounted foam attack. It is rated for 500 gpm (1900 LPM) at 100 psi (7 bar) with a 2.5 in NH female swivel inlet, and the stream pattern is adjusted under flow from 90 degree wide fog to straight jet.
Elkhart states it suits Class A and Class B foams including AR-AFFF, AFFF, FFF and fluoroprotein concentrates, and it is UL Listed. A clear vinyl pick-up hose 9 ft (2.7 m) long is included.
Technical specifications
| Parameter | Specification |
|---|---|
| Manufacturer / model | Elkhart Brass, HF-500 Hydro-Foam self-educting nozzle |
| Rated flow / pressure | 500 gpm (1896 LPM) at 100 psi (7 bar) |
| Inlet | 2.5 in NH female swivel, rocker lug style |
| Type | Constant flow, all stream patterns |
| Foam pick-up rates | 0.5 percent, 1 percent, 3 percent |
| Foam pick-up tube | Clear flexible PVC, 9.0 ft (2.7 m) by 1.25 in ID |
| Material | Corrosion resistant brass, satin finish UNS C84400; aluminium version available |
| Weight | 19.0 lb (8.6 kg) |
| Ambient temperature | -35 °F to 232 °F (-37 °C to 111 °C) |
| Certification | UL Listed |
| Reach at 100 psi (water only) | Straight stream 162 ft; 30 degree fog 80 ft; 90 degree fog 29 ft |
Reach figures in the data sheet are for water only; Elkhart notes foam streams reach about 10 percent less, and that add-on percentages of 1, 3 and 6 percent should be added to flow for the total foam solution flow.
Metering and accessories
The HF nozzles are factory set with a 3 percent metering washer, and 0.5 percent and 1 percent washers are supplied so the rate can be changed in the shop or station by removing the inlet nipple and swapping the washer. The nozzle will pick up foam with as little as 50 psi even though it is rated at 100 psi. Elkhart sells a quick-connect coupling for the pick-up hose, a quarter-turn shut-off valve and a metering valve, as well as drum pick-up kits that pre-connect the foam inlet to a drum or tote.
As with any foam appliance, flush the foam lines with clean water after each use, and lubricate the tip cam periodically with a light petroleum-based grease.

Confirm before ordering
The metering device sets the foam percentage, and the instruction sheet explains how to select 0.5, 1 or 3 percent for the concentrate in use. Always confirm that the selected percentage matches the concentrate manufacturer recommendation for the hazard, and flush the pick-up hose and nozzle with clean water after use so that dried concentrate does not block the metering passages.
Confirm the concentrate type and percentage, finish (brass or chrome plated; aluminium also exists), pick-up accessories and the monitor outlet. Check local requirements for foam use. The attached Elkhart data sheet gives dimensions and reach. Send your details for a quotation and see more Fire Fighting equipment.
