SIMPSON turbo pressure washer nozzle 1/4" QC — 4500 PSI, 4.0 orifice for concrete & decks

The SIMPSON 80144 turbo nozzle is a genuine OEM 1/4" quick-connect turbo tip that delivers an oscillating high-pressure jet rated to 4500 PSI for faster removal of stubborn dirt and grime.

This compact turbo nozzle is a purpose-built accessory for gas pressure washers with a 1/4" quick-connect spray wand. It converts a concentrated stream into a rotating, high-energy jet that penetrates textured surfaces faster than a standard fixed-angle tip. The 4.0 orifice size balances flow and pressure to tackle concrete, decks, and heavily soiled outdoor surfaces while fitting most common extension lances used by DIYers and professionals.

How does this turbo nozzle improve cleaning speed and results?

The rotating jet action increases impact and coverage compared with a steady single-stream tip, breaking up caked-on dirt more quickly. That action reduces the number of passes you need and helps lift debris from rough surfaces.

• Oscillating jet pattern concentrates force while widening effective cleaning area.
• 4.0 orifice provides a balance of flow and pressure for tough stains.
• Designed to clean concrete, pavers, wood decks, and metal surfaces efficiently.

Will this fit my pressure washer and spray wand?

The SIMPSON 80144 uses a 1/4" quick-connect (QC) male end and is made to mate with spray wands and extension lances that accept a 1/4" QC socket. It’s a universal-style OEM part intended for many gas-powered washers, but confirm your wand’s QC size before ordering.

• Requires a spray wand or extension with a 1/4" QC socket.
• Works with most gas pressure washers that use quick-connect accessories.
• Compact footprint keeps reach and maneuverability similar to standard tips.

What pressure, temperature, and flow limits should I follow?

The nozzle is rated to handle up to 4500 PSI and has an orifice size of 4.0. Manufacturer specifications note a maximum temperature figure; however, the part is typically recommended for cold-water use—always follow OEM and washer manufacturer guidance for temperature and pressure limits.

• Maximum rated pressure: 4500 PSI.
• Orifice size: 4.0 for a high-impact flow pattern.
• Follow your pressure washer and SIMPSON guidance on hot-water compatibility and safe operating temperatures.

How do I install and maintain the turbo nozzle for long life?

Installation is a simple push-to-connect onto a compatible 1/4" QC socket. After use, flush the nozzle with clean water, inspect the inlet and bearings for debris, and store it dry to prevent corrosion and preserve the rotating mechanism.

• Push the nozzle into a 1/4" quick-connect socket until it locks.
• Flush with clean water after detergents or heavy use to remove grit.
• Inspect seals and rotating assembly; replace if worn to maintain spray performance.

Who is this for: The SIMPSON 80144 turbo nozzle is well suited to homeowners and contractors who need faster removal of stubborn grime on driveways, patios, decks, and other hard surfaces. If you use a gas-powered pressure washer with a 1/4" quick-connect wand and want an OEM-quality turbo tip rated to high pressure, this model is a compact, durable option to add to your cleaning toolkit.
