PRODUCT OVERVIEW
The Blast-Tec Pro Rotating Turbo Nozzle was designed specifically for high-pressure, high-impact vehicle wash applications, including: wheel blasters, undercarriage wash, rinsing, and high-pressure cleaning.
- Greater Impact: The Blast-Tec Pro blasts a 0° straight water stream at 800-1200 PSI, while the stream rotates at 1500-2500 RPM to provide a 24° or 30° cone of coverage.
- Less Water – Improved stream quality results in greater impingement, allowing you to use a smaller nozzle size and/or reduce the number of nozzles used while getting the same impact as nozzles with higher GPM flow rates.
- Heavy Duty – Corrosion-resistant stainless-steel housing and precision machined tungsten carbide wear surfaces offer long life and smooth operation.
- Long Lasting – The minimal number of components reduces complexity for better reliability. Made with durable materials, the Blast-Tec Pro lasts up to five times longer than ceramic turbo nozzles. Repair kits are also available for extended life and lower overall operating costs.
PRODUCT LINE DESCRIPTION
(See page 5 for part numbers):
Blast-Tec Pro 324 – Nozzle with 24° cone of coverage. Available with either ¼” BSPP or ¼” FNPT inlet connections.
Blast-Tec Pro 430 – Nozzle with 30° cone of coverage. Available with either ¼” BSPP or ¼” FNPT inlet connections.
Repair Kits: Instead of replacing your entire nozzle, repair kits may be used for extended nozzle life. Each repair kit includes a dome screen, mini rotor assembly, and seat retainer assembly.
Accessories:
¼” MBSPP x ¼” MNPT Knuckle Ball Joint Adapter – gives you the flexibility to point your nozzle directly at problems areas such as mirrors, etc. Adjustable ball easily swivels for custom nozzle positioning, adding up to 20 degrees actuation.
¼” MBSPP x 1/8” MNPT Adapter, Brass - 3000581
¼” MBSPP x 1/4” MNPT Adapter, Brass - 3000572
¼” MBSPP x 3/8” MNPT Adapter - 3000988
SPECIFICATIONS
Operating Pressure at Nozzle: 800-1200 PSI.
!WARNING! The correct water pressure is what causes the rotor assembly to rotate properly. Setting pressure too low may cause failure to rotate or laser. Setting pressure too high may cause nozzle to fail prematurely.
Water Temperature: 120°F Max.
Water Quality: Must be PH neutral. 5.5 - 8.5 PH
Water Filtration: 100-micron filtration recommended.
Optimal Operating Distance: 12” – 32” from substrate.
Inlet Connection: ¼” BSPP or NPT. Attach nozzle to proper mating fitting using thread lubricant and these specs:
- ¼” NPT Brass or Stainless: 1-3 turns past finger tight
- ¼” BSPP Brass or Stainless: 15 ft-lbs.
Torque spec on assembling nozzle:
- Housing: 12.5 ft-lbs.
- Inlet to housing 15 ft-lbs.

NOZZLE SELECTION AND SIZING
Proper nozzle selection should take into consideration the type of application, your pressure setting, distance from the substrate, and the nozzle number size.
Pump Capacity – Your pump must be capable of producing 1000 PSI for the total GPM flow rate of all the nozzles required for the application. For example, a wheel blaster with three #4 Nozzles (2 GPM per nozzle) on each the driver’s and passenger’s side (total of 6 nozzles) will require pump capacity of 12 GPM at 1000 PSI.
Or Use This Formula To Calculate:
BSPP vs NPT Inlet Connection:
To meet the needs of the majority of our customers, Blast-Tec Pro Nozzles are available with either ¼” NPT or BSPP inlet connections.
- BSPP Connection – Has an o-ring seal and can be hand-tightened
- NPT Connection – Requires thread tape
Recommendations by Application:
- High Pressure Rinse – Use a higher flow nozzle, position further away from the vehicle
- Tip – Our 30° nozzle will provide better vehicle coverage.
- High Pressure Cleaning – Use a lower flow nozzle, position closer to the vehicle, and/or use more nozzles
- Tip – Our 24° nozzle will provide better cleaning power.

HOW TO INSTALL A REPAIR KIT
Instead of replacing your whole nozzle, you may be able to use a repair kit for extended life and lower overall operating costs. This kit replaces only the common wear parts of the nozzle.
Repair Kit Includes: Inlet screen, Mini-rotor Assembly, and Seat Retainer Assembly.
Tools Required: Small screwdriver, and needle nose pliers

TROUBLESHOOTING
PROBLEM | ANSWERS |
| My nozzle stream is failing to rotate (Lasering). | Check your pressure. For proper rotation, pressure for this nozzle should be set at a minimum of 800 PSI at nozzle. (1200 PSI Max.) |
| Check inlet screen for debris. Clean and/or replace. | |
| Take nozzle apart, check for clogs in the rotor. Clean and/or replace. | |
| Nozzle may fail to rotate based on normal wear and tear. Try inserting a repair kit. | |
| The cross holes on the nozzle inlet may have eroded due to particulate or high-acid reclaim water. Replace nozzle. | |
| Water is going around the nozzle and not through it (Blow-By). | May have a loose body or loose connection. Tighten the nozzle body and inlet connection. |
| Check inlet screen for debris. Clean and/or replace. | |
| Take nozzle apart, check for clogs in the rotor. Clean and/or replace. | |
| Nozzle may fail based on normal wear and tear. Try inserting a repair kit. | |
| The cross holes on the nozzle inlet may have eroded due to particulate or high-acid reclaim water. Replace nozzle. | |
| No flow, low flow, or not enough impingement. | Increase your pump pressure. (Pump must remain between 800 PSI (min) and 1200 PSI (max). Check for desired result. |
| Move applicator or nozzle closer to the substrate. Check for desired result. | |
| Change nozzle to a larger nozzle size (higher flow rate). Check for desired result. | |
| Too much impingement, nozzle is causing damage. | Decrease your pump pressure. (Pump must remain between 800 PSI (min) and 1200 PSI (max). Check for desired result. |
| Change nozzle to a smaller nozzle size (lower flow rate). Check for desired result. | |
| Move applicator or nozzle further from the substrate. Check for desired result. |
