Hilmor Orbital Flare Flaring Tool for HVAC/Refrigeration, 3/16"–3/4" Gray/Black — 45° Clutch & Spring Clamp

The Hilmor 1838952 Orbital Flare is a handheld flaring tool that forms consistent 45° flares on copper, aluminum, steel and brass tubing from 3/16" to 3/4" for HVAC and refrigeration work.

Built for service technicians and installers, this compact gray-and-black flaring tool combines a spring-loaded clamp, positive tubing stop, and a clutch-style yoke to produce precise, repeatable fittings across a broad range of soft metals. It measures 8.5" long, 4.6" wide, 5.3" high and weighs 3.8 lbs—small enough for tight spaces yet robust for repeated field use.

How does the Orbital Flare produce reliable 45° flares?

The tool uses an orbital cone that rotates into the tubing while the yoke holds the clamp steady, shaping a true 45° flare without cutting or compressing the tube wall. A built-in clutch clicks when the flare is complete, preventing over-torquing and reducing the risk of cracked tubing.

• Spring-loaded clothespin block for fast clamp release and secure hold
• Tubing stop ensures consistent flare height for proper fittings
• Detents and screw bar align the yoke for concentric flares
• Clutch mechanism stops at the correct torque to avoid over-flaring

Which tubing sizes and metals can this flaring tool handle?

This Hilmor model covers a wide range of soft-metal tubing sizes used in HVAC and refrigeration systems, from small capillary lines up to larger service lines. It’s compatible with copper, aluminum, brass and softer steel—materials commonly found in installation and repair jobs.

• Supported tube diameters: 3/16", 1/4", 5/16", 3/8", 1/2", 5/8", 3/4"
• Works with copper, aluminum, brass, and soft steel tubing
• Design maintains concentricity to improve joint sealing and fit

How easy is it to use the Hilmor Orbital Flare on the job?

Operation is straightforward: secure the tube in the clamp, set the tubing stop, then turn the handle until the clutch clicks. Spring-assist clamp opening and clear alignment features speed repeated flares and reduce set-up time in tight or overhead applications.

• Quick clamp action minimizes time per flare
• Simple handle turn creates the flare with an audible click at completion
• Detents and screw bar keep yoke aligned through multiple operations

What durability and portability features matter for fieldwork?

The Orbital Flare combines a durable construction with a compact footprint so technicians can carry it in tool bags and use it in cramped mechanical spaces. Corrosion-resistant components and a robust yoke design are intended to tolerate regular site use without frequent maintenance.

• Compact dimensions: 8.5" L x 4.6" W x 5.3" H for easy transport
• 3.8 lb weight balances sturdiness and portability
• Rugged finish to resist job-site wear and tear

Who is this for: The Hilmor 1838952 Orbital Flare suits HVAC/R technicians, refrigeration service professionals, and skilled DIYers who need a reliable, multi-metal flaring tool. If you regularly form 45° flares on tubing from 3/16" to 3/4" and work in confined spaces, this tool offers a compact, repeatable solution that reduces over-flaring and speeds installations and repairs.
