What's Included
Why Premium? The ST-167 Bypass Advantage
- Bypass for maximum rinse power: In rinse mode, high-pressure water flows around the injector instead of through it, so you rinse at full pressure.
- One-lever switching: Go from soap to rinse without disconnecting anything or changing tips.
- Precise dilution: Metering tips set your soap ratio so every wash is consistent.
- Built to last: Stainless steel body rated to 5,000 PSI and 212°F.
Premium Single Soap Wash System: The Foaminator
Pairing our Premium Single Soap Wash System with our custom lance (The Foaminator) is the ultimate combo. It speeds up your wash and saves you time and money. Swapping attachments, dealing with foam cannons and using buckets become a thing of the past.
What's Included:
- The Foaminator Wash/Rinse Lance
- Suttner ST-167 stainless bypass injector
- Stainless J hooks for wall mounting storage of your gun (2 hooks)
- Braided soap hose (10 feet)
- Stainless MEG (rinse) tip custom fitted for your GPM / PSI (1 tip)
- Internal foam nozzle custom fitted for your GPM / PSI (1 nozzle)
- Premium soap draw tube with mesh screen (1 draw tube)
- Metering tips for precisely diluting your soap (1 bag, 6 pc)
Please note: Image Wash Products will call you after you place your order to get your pressure washer's PSI and GPM before we build your system. These injectors and foam heads are custom built to work with your exact pressure washer, so we need those specs to start your build. To make full use of these systems, a pressure washer with a minimum of 2.5 GPM is required.
How It Works:
The ST-167 has two modes, selected with its lever:
- Soap mode: Water is routed through the injection chamber. The pressure change draws soap right out of the container and into your line, perfectly diluted every time.
- Bypass (rinse) mode: High-pressure water is routed through bypass bores parallel to the injector. No chemical is drawn in and no rinse pressure is lost.
ST-167 Specifications:
- Stainless steel body
- Maximum pressure: 5,000 PSI
- Maximum temperature: 212°F
- 3/8" female inlet and outlet
- Chemical pick-up hose barb (inlet)
- Dosing nozzle / orifice sized to your pressure washer
Selecting Your Nozzle:
Choose the orifice that's right for your pressure washer based on its PSI and GPM. Once you have your PSI and GPM, use the chart below to select the right nozzle.
Which Image Wash chemicals run through this system?
These setups come from our Soap System Calculator. Enter your pressure washer's PSI and GPM there to get the exact metering tip for each chemical.

Not for soap injectors: Bug Remover, Iron Remover, Quick Detailer, Interior Detailer and Tire Shine Pro are sprayer products. Polished Aluminum Cleaner needs a stronger mix (15:1) than an injector delivers.
Soap system FAQs
How do I pick the right metering tip?
Enter your pressure washer's PSI and GPM in our Soap System Calculator. It shows which tip each chemical needs on your machine. Every system is built in Hudsonville, MI and sized to your pressure washer, so call 616.777.7175 if you have questions.
Can I run a touchless 2-step with a single soap system?
A single soap system draws one chemical at a time. For a 2-step wash without swapping draw tubes, step up to our Dual Soap Injector System.
Do I have to pre-mix my soap?
Some chemicals run straight from the drum and some need a pre-mix, as shown in the chart above. Pre-mixing gets concentrates to the right strength for the injector's draw.
Can I run acid brighteners through it?
Alum-Brite Lite and Total Brite 1 appear in the calculator for injector use. They are not polish-safe and contain hydrofluoric acid, so read the SDS, use acid-resistant equipment where called for, and always follow with a high-pH Step 2.
