Genuine Imperial S74833 cutter wheel to suit the 406-FA Adjust-O-Matic tube cutter. Built for Aussie refrigeration techs who want clean, repeatable cuts on metal tubing—swap it in and crack on with the job, no worries. Verified fit for the 406-FA. 

Key Features & Trade Benefits

• Correct fit for 406-FA — The wheel specified for Imperial’s 406-FA tube cutter. Stops the guesswork and gets you back on the tools faster. 
• General-purpose profile — Suitable for common HVAC/R tubing metals. Smoother, consistent cuts that help reduce flare leaks and rework. 
• Stable cutting action — Designed to track straight in the 406-FA head. Less wandering, more fair-dinkum accuracy when you’re on a ladder or roof.
• Quick swap-out — Direct replacement with the correct retaining screw. Minimise downtime between cuts—she’ll be right. 
• Genuine Imperial part — Backed by the brand many fridgies trust. Durable, field-proven performance on commercial sites.

Why This Product Matters

Ever tried to dial a clean cut on 3 mm wall copper when your wheel’s glazed? It skates, work-hardens the edge, and your flare looks crook. Swap to a fresh S74833 in the 406-FA and the cut tracks straight, the burr is manageable, and the joint seals first go. That’s fewer call-backs and a happier site manager—too easy.

Pro Tip

After swapping the wheel, give the feed screw a quick clean and a dab of light oil. Make a light scoring pass, then tighten in small increments—don’t over-crank. Finish with a quick deburr so flares seat perfectly and you don’t nick O-rings down the track.

Compatibility & System Info

• Fits: Imperial 406-FA Adjust-O-Matic Tube Cutter (the 406-FA ships with two S74833 wheels from factory).
• Use on: Common HVAC/R tubing metals like copper, aluminium, brass and thin-wall steel (per Imperial distributors).
• Retaining screw: Use the dedicated S74834 screw for the 406-FA head. 

Local note: From hot Sydney rooftops to breezy Perth workshops, a sharp wheel means fewer spins of the ratchet and a cleaner face on the tube—bloody good for productivity.

FAQs

Is this the correct wheel for my 406-FA?
Yes. The 406-FA uses S74833 wheels from factory, and this is the genuine replacement. 

What metals does it cut?
General-purpose profile suitable for copper, aluminium, brass and thin-wall steel commonly used in HVAC/R. For soft copper-only work, consider an extra-sharp wheel (see below). 

Do I need a new retaining screw?
If the screw is worn or stripped, replace it with the Imperial S74834 screw for the 406-FA head so the wheel tracks true.
