Tritech tips are unique in that they have super hard tungsten at 93 Rockwell hardness & all other brands are about 83-85 Rockwell hardness. Persevering with a worn spray tip will simply end up costing you money and will produce inferior results. You’ll start using more paint for the same area coverage and the spray pattern will be more uneven. However, airless spray tips are subject to enormous pressures and do wear out just like any other painting tools.Ī tip will spray, on average, around 300-600 litres before you need to replace it.Ī new tip should produce a soft, thinner coated edge around the spray fan.Īs the tip wears, this soft edge will become more defined and the fan size will decrease. The Tritech tips, for example, are made with super hard tungsten carbide measuring 93 on the Rockwell scale of hardness.Īs a comparison, a diamond measures 100 on this same scale. We supply the toughest tips in the industry. Having said that, the range of tip sizes available allows you almost infinite control of your spraying finish and quality. When it comes to choosing tips, you should start by checking the coating manufacturer’s instructions they have researched optimum tip sizes for the viscosity of their particular products. On the other hand, keeping the orifice size the same and increasing the fan width allows you to spread the same amount of material over a wider area. Both tips will spray a pattern 10 inches wide but the 523 tip will produce a thicker coating provided you use the same sprayer pressure and hand speed. These three numbers together tell you a lot about whether the tip is suitable for your needs.īut what happens when you compare two tips with the same fan width but with different orifice sizes?Ī 515 tip compared with a 523 tip. Higher pressures will force more material through the orifice. The amount of pressure used will also influence this. The larger the orifice, the more paint can come through it. The size of this opening controls how much coating material can flow out through the tip. Thus, a 515 tip denotes an orifice measuring 15 thousandths of an inch in diameter. The last two digits indicate the size of this orifice in thousandths of an inch. The tip orifice is where final paint atomisation occurs. This is a general guide because the fan width may vary slightly depending on the sprayer pressure and material choice by up to 2 inches (5cms). Yes, even in Australia, we still use inches for this measurement.įor example, a 515 tip will give you a spray fan pattern 10 inches wide (2 x 5) when the sprayer is approximately 12 inches (30 cms) from the surface.Ī 315 tip will produce a 6-inch wide spray fan, a 413 tip will produce an 8 inch and so on.Īlready know what tips you need? See our range here Take the first digit double it and this will give you the width of the spray fan in inches. Spray tip size is designated by three numbers.
