6290NX-4 - Flame Tech 6290NX-4 Propane Cutting Tip, Size 4, Harris Style

Cut Thick Steel with Confidence

When you are staring down a 4-inch slab of steel and need a clean cut without blowing your budget on acetylene, the Flame Tech 6290NX-4 is the tip you reach for. Designed specifically for Harris style torches, this size 4 tip turns your propane or natural gas setup into a heavy-duty cutting station. We know that propane requires a different approach than acetylene—specifically, it needs more preheat to get the cut started. That is why this tip features a heavy preheat spline configuration. It delivers the heat you need to pierce and slice through thick plate, ranging from 3 inches all the way up to 6 inches, without the frustration of lost cuts or slow starts.

Durability is key in any shop environment, and this tip is built to last. The two-piece construction isn't just for show; it allows you to take the tip apart and clean out any slag or debris that might clog the preheat holes, extending the life of your consumable. The copper outer shell resists heat and spatter, while the brass inner core ensures consistent gas flow. Whether you are scrapping heavy machinery or fabricating structural beams, this tip gives you the performance of a top-tier brand at a price that makes sense for your bottom line. Pop it into your Harris torch, set your pressures, and experience smooth, efficient cutting on the thickest jobs in the shop.
