6290NX-5 - Harris Style 6290NX-5 Propane Cutting Tip - Size 5 Heavy Duty

Cut Thicker Steel for Less

When the job calls for slicing through massive steel slabs, the Generic 6290NX-5 Propane Cutting Tip is your go-to solution. Built to fit any standard Harris-style torch, this tip allows you to leverage the cost-effectiveness of propane or natural gas without sacrificing cutting power. With a massive cutting capacity of 6 to 8 inches, this Size 5 tip is designed for the big jobs—structural demolition, heavy equipment repair, and thick plate fabrication where standard tips just can't reach.

Why Choose Propane Tips?

Propane is often readily available and cheaper than acetylene, but it requires a specific tip design to work effectively. This 6290NX-5 tip features a specialized two-piece design. The heavy copper outer sleeve protects the internal brass splines from the intense heat reflected off thick steel plates. This design creates a stable, high-velocity preheat flame that cuts through rust and scale, getting your metal up to ignition temperature quickly so you can start your cut and keep moving.

Durability on the Job Site

We know that cutting gear takes a beating. Whether you are in a scrap yard or on a construction site, you need consumables that last. The chrome-plated outer shell of this tip helps resist spatter adhesion, making it easier to wipe clean after a long shift. The heavy-wall construction resists deformation from heat, ensuring that your gas flow remains consistent cut after cut. Because it is a generic replacement, you get the same reliable fit and performance as the big-name brands but at a price point that keeps your project under budget.

Getting the Best Cut

To get the most out of this Size 5 tip, ensure your regulator is set correctly. You'll need a strong oxygen supply—around 65-80 PSI—to blow the slag out of an 8-inch cut. Pair this with a standard propane fuel setting, and you will see clean, vertical cuts with minimal slag accumulation. Stop struggling with undersized tips and upgrade your torch kit with the 6290NX-5 for your heavy-duty cutting needs.
