- Brass + ABS Dual-Material Body (27 x 8 cm): The IFG500 combines a corrosion-resistant brass core with a robust ABS polymer housing, delivering a tool that withstands prolonged exposure to chemical agents, foam compounds, and high-pressure water without degradation — ensuring a long service life even in demanding site conditions.
- G1/4"-F Universal Inlet Interface: Fitted with a standard G1/4" female thread, the IFG500 connects directly to the vast majority of professional and consumer pressure washers on the market, eliminating the need for adapters and enabling fast, tool-free attachment and detachment on the job.
- 1-Litre Foam Bottle Capacity with 2.0 GPM Flow Rate: The generous 1-litre reservoir paired with a steady 2.0 GPM (gallons per minute) flow rate ensures consistent foam output over extended application runs — reducing refill interruptions and improving coverage efficiency on large surface areas or deep cavity fills.
- Wide Pressure Operating Range — 70 bar to 200 bar (1000–3000 psi) with 5.3 GPM Max Flow: Designed to perform across a broad spectrum of pressure washer outputs, the IFG500 operates reliably from 70 bar minimum up to a 200 bar maximum, with a peak flow capacity of 5.3 GPM — making it compatible with both entry-level and high-output professional pressure washers.
- Thermal Tolerance up to 60°C / 140°F: Rated for use with warm and hot water pressure washers up to 60°C (140°F), the IFG500 maintains structural integrity and seal performance in elevated-temperature environments — critical for applications involving heated cleaning solutions or warm-water foam systems.
The IFG500 is supplied with CE Machine Test certification, confirming it meets European safety and performance standards for pressure equipment. The package includes the foam spray gun, 1-litre bottle, and all necessary fittings for immediate use straight out of the box.
General Purchase & Comparison Queries
Is the IDEAL IFG500 compatible with my existing pressure washer?
The IFG500 uses a standard G1/4" female (F) inlet thread, which is the most widely adopted connection standard across professional and consumer pressure washers globally. As long as your pressure washer outputs between 70 bar (1000 psi) and 200 bar (3000 psi), the IFG500 will connect and operate without adapters. If your machine uses a different thread standard, a G1/4" adapter is all that is needed.
How does the IFG500 compare to cheaper foam guns on the market?
Budget foam guns are typically made entirely from plastic, which degrades quickly under high pressure and chemical exposure. The IFG500 features a Brass + ABS composite construction — brass at the critical pressure-bearing components for longevity, and ABS for lightweight handling. It is also CE Machine Test certified, meaning it has been independently tested to European safety standards — a level of quality assurance rarely found in lower-cost alternatives.
Can I use the IFG500 for both foam insulation and pressure washing foam detergent?
Yes. The IFG500 is a versatile foam spray gun accessory suitable for both construction-grade foam insulation/sealant application and pre-wash foam detergent use in vehicle or equipment cleaning. Its 1-litre bottle accommodates a wide range of foam compounds. Always flush the gun with clean water after switching between chemical types to prevent cross-contamination and maintain performance.
Product-Specific and Usage Queries
What is the maximum pressure and flow rate the IFG500 can handle?
The IFG500 is rated for a maximum pressure of 200 bar (3000 psi) and a maximum flow rate of 5.3 GPM. The minimum required operating pressure is 70 bar (1000 psi) with a standard working flow of 2.0 GPM. Operating within these parameters ensures optimal foam consistency and protects the gun's internal seals and mixing chamber from premature wear.
Can I use hot water with the IFG500?
Yes. The IFG500 is thermally rated for water temperatures up to 60°C (140°F), making it compatible with warm-water and hot-water pressure washers. This is particularly useful for applications involving heated cleaning solutions or foam compounds that activate more effectively at elevated temperatures. Do not exceed the 60°C limit, as this may compromise the ABS housing and internal seals.
How large is the foam bottle and how long does it last per fill?
The IFG500 comes with a 1-litre foam bottle. At the standard working flow rate of 2.0 GPM, a full bottle provides continuous foam output for several minutes of uninterrupted spraying — sufficient for covering large wall sections, vehicle panels, or cavity fills in one pass. For extended jobs, the bottle is designed for quick refilling without tools.
Problem/Solution-Oriented Queries
The foam output is weak or inconsistent — what should I check?
Weak or inconsistent foam is most commonly caused by insufficient inlet pressure. Ensure your pressure washer is delivering at least 70 bar (1000 psi) — the IFG500's minimum operating pressure. Also check that the G1/4" connection is fully tightened with no air leaks, and that the foam bottle is not empty or the compound has not thickened due to temperature. Flushing the nozzle with clean water can also clear partial blockages affecting flow.
There is a leak at the connection point — how do I fix it?
Leaks at the G1/4" inlet connection are typically caused by a missing or worn thread seal (PTFE tape) or an incompletely threaded connection. First, ensure the gun is threaded fully and hand-tightened firmly. If the leak persists, wrap 2–3 layers of PTFE plumber's tape around the male thread of your pressure washer lance before reconnecting. Do not over-torque the brass fitting, as this can crack the thread.
The nozzle is clogged and foam is not spraying — what should I do?
Nozzle blockages in the IFG500 are usually caused by dried or hardened foam compound left in the gun after use. To clear the blockage, detach the foam bottle and run clean water through the gun at low pressure to dissolve residue. For stubborn clogs, soak the nozzle tip in warm water for 10–15 minutes. To prevent future blockages, always flush the gun with clean water immediately after each use before storing.
