Description
Built for Aussie HVAC/R and auto A/C techs, the Imperial 375FS delivers clean, repeatable 45° flares from 1/8″ to 3/4″ O.D. in soft copper, aluminium and brass. A quick slip-on yoke and chrome-finished swivel cone cut effort, while the positive clamping bar stops tube creep. Tough nickel-chrome finish stands up to site abuse. Fair dinkum kit.
Key Features & Trade Benefits
- Wide size range (1/8″–3/4″ O.D.) — one tool covers common liquid/suction and auto A/C sizes, reducing van clutter.
- Slip-on yoke + swivel cone — hard chrome cone reduces drag; faster, smoother flares with less muscle.
- Positive clamping bar — locks the tube so the flare forms square and true; fewer reworks.
- Nickel-chrome finish — durable, corrosion-resistant body for long service life.
- Includes tool case — keeps dies and bar together for quick grab-and-go.
Why This Tool Matters
On a humid Sydney rooftop, you’ve got a tight coil change and a couple of 1/2″ flares to pull. With the 375FS, it’s mark, clamp, smooth draw to 45° — flare seats first go, torque up, leak test, done. Next morning in Melbourne, it’s auto A/C line repairs — same tool, same tidy result. No dramas and fewer call-backs.

Pro Tip
Deburr inside and out before you flare, then lightly oil the cone. Aim the tube end to sit flush and square in the bar — that’s what stops split flares and weeping joints. She’ll be right when the prep’s right. Pair with a quality cutter and deburrer for spot-on results.
