The Blue SGS35 spray gun is MTM Hydro's full-size Acqualine trigger gun, rated to 5,000 PSI and 12 GPM in a blue food-grade housing. An integrated stainless live swivel and easy-hold trigger cut hose kink and hand fatigue. Pick it with or without quick connects.
Key Features
-
5,000 PSI, 12 GPM: Handles commercial cold- and hot-water machines up to a 5,000 PSI rating.
-
Blue food-grade housing: The shockproof reinforced-plastic shell is food-grade for OSHA and FDA regulated facilities.
-
Integrated stainless live swivel: The inlet rotates under pressure, so the hose won't kink or twist your wrist through a long session.
-
Ceramic ball valve: A ceramic ball in the nickel-plated brass valve resists wear better than a plain-brass budget gun.
-
Easy-hold trigger: Lighter holding force than a standard trigger gun, which saves your hand on long flatwork jobs.
-
Rebuildable: MTM repair kit 41.0535 rebuilds the ceramic ball, seat, spring, and seals instead of tossing the gun.

What's Included
- 1 blue SGS35 spray gun with integrated stainless swivel
- Stainless QC plug (inlet) and coupler (outlet) on the With QC option (10.5008); the Without QC option (10.5010) ships with bare threads
Connects between your pressure hose and a lance, wand, nozzle, or foam cannon. The 3/8" inlet takes a standard pressure hose or an M22 14mm or 15mm adapter, and the 1/4" outlet takes quick-connect nozzles and MTM foam cannons like the PF22.2. It's not for potable water, and it's not a low-pressure 12V soft wash gun.
How the Blue SGS35 Spray Gun Works
The SGS35 sits between your pressure hose and the lance or nozzle. Pressurized water enters the stainless swivel inlet, and pulling the trigger lifts a ceramic ball off its seat to send flow to the 1/4" outlet. Release the trigger and the ball reseats to stop flow. The live swivel lets the hose rotate under pressure so it won't kink or tangle, and the easy-hold trigger drops the holding force so your hand lasts through a full day.
It's rated to 320°F, but that covers the internal piping. The factory nitrile o-rings top out around 250°F, so for hot-water work swap to Viton seals, which are good to about 400°F. One honest note on chemicals: the blue food-grade housing is the outer shell, not the wetted path. The valve is nickel-plated brass with nitrile seals, so this is a pressure-washing gun, not a soft wash gun. Daily SH corrodes brass and breaks down nitrile, so for bleach work run a poly or stainless soft wash gun instead.

Frequently Asked Questions
What's the difference between the With QC and Without QC options?
Fittings only. The With QC version (10.5008) ships with stainless quick connects installed on the inlet and outlet. The Without QC version (10.5010) is the same gun with the integrated swivel but no fittings, so you add your own. Same 5,000 PSI, 12 GPM gun either way.
Can I use the Blue SGS35 for soft washing or bleach?
No. The food-grade housing is the shell, not the wetted valve. The valve is nickel-plated brass with nitrile seals, and daily SH corrodes brass and breaks down nitrile. For soft wash and bleach, run a poly or stainless gun like the WaterBoss 750 Soft Wash Gun or the ST-510 Poly Trigger Gun.
Can I run hot water through the Blue SGS35?
It's rated to 320°F, but that covers the internal piping, not the seals. The factory nitrile o-rings top out around 250°F, so for hot-water systems swap to Viton seals. Viton is good to about 400°F, which clears the gun's rating.
