Thermal Dynamics 9-8253 is the 120A cutting tip for the SL60 and SL100 1Torch plasma torches, used on Thermal Dynamics Cutmaster and Victor air plasma cutters (120 A). This is an aftermarket part made to the same number and fit.
Machined copper tip with a flanged base; the orifice size sets the current it is meant for. Fit the tip that matches the amperage you cut at, and change it together with the electrode.
Check the number on your old part or in the torch manual before ordering: it should read 9-8253. Sold in packs of 10.

Routine changes
Change the nozzle when the orifice is no longer round, is oversized or shows a burned edge. A damaged nozzle gives a wider, bevelled cut and more dross.
Matching the current
Fit the nozzle that matches the current you cut at. Running a nozzle above its rating burns the orifice out quickly.

Yes, it was made for the Thermal Dynamics SL60, and 1 more listed under compatible equipment. Check the old plasma nozzle is marked 9-8253 or one of the cross references, because makers change parts between serial ranges.
On the Thermal Dynamics SL60, laser and plasma nozzles wear in days to weeks, depending on hours of arc or beam time, material and gas. Change it on condition, not by date.
An oval or nicked orifice, spatter stuck on the tip, more dross, a wider cut or bevel on one side, and height sensing errors.
Look at the orifice: if it is oval, nicked or has spatter stuck to it, the cut quality falls. Change it before it damages the parts behind it.
Centre the nozzle on the beam and recalibrate the height sensor. A new nozzle off centre cuts on one side only.
No. It is an aftermarket plasma nozzle made to replace the Thermal Dynamics 9-8253. It is not made by the original manufacturer; the number only shows what it replaces.
