Welcome to our dedicated guide on Imperial Pipe Benders, where you'll find two standout triple-head tube benders designed for professionals who demand precision and durability. These tools, the 470FH with Roto-Lok Indexing Handle and the 370FH, handle bends up to 180 degrees on common tubing sizes, making them essential for plumbers, HVAC technicians, and automotive mechanics tackling tight spaces and complex installations.
Why Choose Imperial Pipe Benders?
Imperial has built a stellar reputation over decades for crafting high-quality hand tools that withstand rigorous daily use. Their pipe benders stand out with robust construction, smooth bending action, and innovative features like indexing handles that lock securely for consistent results. Unlike lesser tools that kink or flatten tubes, Imperial models deliver clean, professional bends every time, saving you rework and frustration on the job.
Part of our broader Pipe Benders category within Hand Tools, these Imperial options excel in scenarios where portability and versatility matter most. Whether you're navigating crowded engine bays or installing refrigerant lines, their compact triple-head design covers multiple sizes in one tool.
Key Features to Look For
When shopping for pipe benders, prioritize these attributes to match your needs:
- Bending Radius and Capacity: Imperial benders offer tight radii for 180-degree U-bends without tube deformation.
- Multiple Heads: Triple-head setups handle 3-4 common sizes, reducing the need for tool swaps.
- Handle Design: Ergonomic, indexed handles like the Roto-Lok provide leverage and prevent slippage.
- Material Durability: Alloy steel construction resists wear, ideal for soft metals like copper, aluminum, and light steel.
- Portability: Lightweight yet sturdy, perfect for tool belts or job site kits.
These features ensure Imperial benders perform reliably across Tools & Home Improvement applications, from DIY projects to pro installations.
Comparing Imperial Models: 470FH vs 370FH
Both models share Imperial's hallmark precision but cater to slightly different tubing ranges, helping you choose based on your primary work.
The 470FH Triple Head Bender with Roto-Lok Indexing Handle targets smaller diameters: 3/16", 1/4", 5/16", and 3/8". Its rotating handle locks at multiple angles for superior control in confined spaces, making it a favorite for refrigeration and instrumentation work. The indexing feature minimizes handle interference, allowing full 180-degree bends effortlessly.
In contrast, the 370FH Triple Head Bender covers 3/16", 1/4", 3/8", and 1/2", suiting larger plumbing and hydraulic lines. It offers the same smooth action but with a traditional handle, providing ample leverage for tougher materials. If your projects involve bigger tubes, this model's expanded range shines.
| Model | Sizes | Handle Type | Best For |
|---|
| 470FH | 3/16", 1/4", 5/16", 3/8" | Roto-Lok Indexing | Tight spaces, HVAC |
| 370FH | 3/16", 1/4", 3/8", 1/2" | Standard | Plumbing, larger lines |
Imperial's engineering ensures both outperform many competitors. For instance, when stacked against Klein Tools Pipe Benders, Imperial's triple-head versatility often wins for multi-size jobs, while holding its own in durability.
