Suttner ST-2315 Trigger Gun, Pre-Fitted with 3/8" Quick Connects
This is the same acid-resistant Suttner ST-2315 pressure washer trigger gun we sell as a bare gun, but it arrives with 3/8" quick connects already installed on both ends. The inlet takes a 3/8" quick-connect plug that snaps into your pressure washer hose, and the outlet has a 3/8" quick-connect coupler that your lance, foam lance, or nozzle extension snaps into. There's no thread tape, no hunting for adapters, and no wrenches. Take it out of the box, click it onto your hose and lance, and start washing.
Built for harsh chemicals and heavy daily use, the ST-2315 is a go-to gun for fleet washing, truck washing, aluminum brightening, and two-step touchless soap systems.
Why Choose the Quick-Connect Version?
- Ready to use out of the box: 3/8" quick connects are installed on the inlet and outlet, so there's nothing extra to buy or install
- Fast lance changes: swap between a rinse lance, foam lance, or soap wand in seconds
- Quick hose hookup: snap the gun onto any hose with a 3/8" quick-connect coupler
- Acid and chemical resistant: made to handle aggressive soaps, acids, and brighteners
- Comfortable to use all day: an ergonomic grip and smooth trigger pull reduce hand fatigue on long wash jobs
- Trigger lock: a built-in safety lock helps prevent accidental spraying
- Made in Germany: Suttner professional-grade build quality

Need just the trigger to thread into an existing setup? Choose our bare Suttner ST-2315 acid-resistant trigger, which has a 3/8" female inlet and a 1/4" female outlet. Choose this quick-connect version if you want to snap your hose and lances on and off without tools.
Frequently Asked Questions
What size quick connects are installed?
Both ends use 3/8" quick connects. The inlet has a 3/8" plug that snaps into a hose with a 3/8" quick-connect coupler, and the outlet has a 3/8" coupler that accepts any lance or accessory with a 3/8" quick-connect plug.
What pressure washers does it work with?
Any pressure washer rated up to 5,000 PSI, 12 GPM, and 300°F that uses a 3/8" quick-connect hose. Don't exceed any of those ratings.
Is it safe to use with acid and harsh chemicals?
Yes. The ST-2315 is an acid- and chemical-resistant trigger gun designed for aggressive soaps, acids, and aluminum brighteners. Flush it with clean water after using harsh chemicals.
Can I use it for hot water pressure washing?
Yes, up to 300°F.
Does it have a trigger lock?
Yes. The ST-2315 has a built-in trigger safety lock. Engage it whenever you aren't actively spraying.
What's the difference between this and the bare ST-2315 trigger?
It's the same gun. This version comes pre-assembled with 3/8" quick connects on the inlet and outlet for tool-free hose and lance changes. The bare trigger has threaded ports (3/8" female inlet, 1/4" female outlet) for permanent or custom plumbing.
