## Description

Universal replacement THREADED type NOZZLE for surface cleanersFits our any surface cleaner with 1/4” female pipe thread spray bar outletsBest suitable for 4000PSI @ 3.0GPM (will also work with surface cleaners with 2500PSI @ 2.3GPM, 3000PSI @ 2.5GPM, 3500PSI @ 2.8GPM OR 5000PSI @ 3.3 GPM.). Using the nozzles outside these parameters will cause the surface cleaner to underperform.25 Degree nozzle high pressure screw type spray tip nozzleOrfice size: 1.5; 1/4" Male NPTStainless steel nozzle with hardened insertIdeal for cold & hot water applicationsTip#1: If your surface cleaner is making zebra stripes, and your pressure washer is producing less than 4.0GPM, push the surface cleaner at a slower pace. This will give your unit more time to clean. More water flow -> faster the cleaning.Tip#2: If your surface cleaner vibrates or the spray bar does not spin, this is due to the clogged or partially clogged nozzle. Remove the nozzles and clean with fresh water. This should stop the vibrating and a water leak of the swivel head.

## Questions & Answers

**Q: Do you screw these in flush or leave some threads exposed?**
A: In order to make the best water-tight seal, screw these nozzles in flush.  We also suggest using Teflon tape to make a good seal as well.

**Q: My tips are completely clogged. I can't blow any air through them even with my compressor. Any ideas how to deal with stubborn clogs?**
A: Depends what they are clog with, but often soaking in WD40 or PB Blaster can help dissolve deposits. Soaking in vinegar can help if deposits are from hard water. If clogged with grit or deposits that don't dissolve, time for new nozzles.

**Q: Do these need thread locker tape or lock tight?**
A: Yes, it is suggested to use Teflon tape or locktite in order to make a good water tight seal.

**Q: What does the 1.5 orifice mean?  Is it 1.5mm dia or does it related to a flow coefficient (Cv)?**
A: 1.5 gpm gallons per minute

## Customer Reviews

### ⭐⭐⭐⭐⭐ Teflon tape and make sure jet is parrallel with arms
*by K***S on June 16, 2018*

Perfect restored the pressure

### ⭐⭐⭐⭐ Didn’t help my situation
*by S***R on July 26, 2023*

These wouldn’t thread as deep as the original nozzles on my north star 20” surface cleaner. They did work but with my DEWALT 3800 psi 3.5 gpm washer the spray was too intense and was doing minor damage to my driveway.

### ⭐⭐⭐⭐⭐ Good
*by J***N on September 10, 2018*
