Imperial Tool 370FH Triple Head 180 Degree Tube Bender - Smooth 180

In this review the Imperial Tool 370FH Triple Head 180 Degree Tube Bender is evaluated for trade and home use, and the bottom line is simple: it is a compact, reliable bender that produces consistently smooth 180 degree bends in soft copper, aluminum, and thin wall steel with minimal effort. The tool is ideal for plumbers, HVAC technicians, and DIYers who need repeatable, tight-radius bends in 1/4 in, 3/8 in and 1/2 in tubing; its integrated calibrated markings and cushioned handles speed layout and reduce fatigue.

Key Features

• Triple head design: Allows bending of 1/4 in, 3/8 in and 1/2 in O.D. tubes with a single tool, reducing trips to the toolbox.
• Integrated calibrated markings: Built-in left-hand, right-hand and offset markings make it faster to set bend points and maintain accuracy on repeat jobs.
• Patented Roto-Lok Indexing Lever: Provides smoother action and improved control so tight 180 degree bends require less exertion.
• Cushion grip handles: Lightweight die-cast aluminum bodies with deluxe grips minimize hand fatigue during prolonged use.
• Suitable materials: Works reliably on soft copper, aluminum and thin wall steel, covering the most common trade tubing needs.
• Adjustable hook: Helps secure tubing while bending so the operator maintains alignment and consistent radii.

Who It's For

The Imperial 370FH is best for professionals and experienced DIYers who regularly bend small-diameter tubing and need a durable hand tool that delivers clean, tight 180 degree bends. Plumbers and HVAC technicians will appreciate the calibrated markings and the ability to handle multiple tube sizes without swapping tools.

It is less suited to users who need to bend larger diameter or heavy wall tubing, or those who require a powered bender for high-volume production. Occasional users should still find it intuitive, but may not need the heavier-duty longevity professionals demand.

Pros & Cons

Pros

• Produces smooth, consistent 180 degree bends across 1/4 in, 3/8 in and 1/2 in tubing sizes.
• Integrated markings and adjustable hook speed layout and improve accuracy on left-hand, right-hand and offset bends.
• Comfortable cushion grip handles and lightweight die-cast construction reduce operator fatigue.
• Patented Roto-Lok indexing lever reduces effort required for tight bends and improves control.

Cons

• A small number of users report durability problems under heavy or improper use, so care is required to avoid overstressing the tool.
