Hilmor HVAC Tools

Hilmor HVAC tools are a purpose-built line of tube working, service, and hand tools designed for professional HVAC/R technicians who need precision and durability across every task on the job. From bending 1/4" to 7/8" copper lineset to pulling vacuum down to 25 microns, Hilmor HVAC tools cover the full range of installation and service work without the bulk or the breakdowns. The line spans tube benders, flaring tools, swaging tools, vacuum pumps available in 3, 5, 9, and 12 CFM, manifold gauges, refrigerant hoses, recovery machines, and service wrenches, all engineered around one-handed operation and compact form factors that actually fit where contractors need them. Designed for technicians who move from job to job, Hilmor HVAC tools address the most common friction points in the field, from cramped mechanical rooms requiring reverse-angle bends to the precision flaring that A2L refrigerant systems increasingly demand.

KEY SUBCATEGORIES / PRODUCT TYPES

Tube Bending Tools

Hilmor tube bending tools are ratcheting, one-handed benders engineered for HVAC/R lineset work. The Hilmor Compact Bender Kit (SKU 1839032) handles 1/4", 5/16", 3/8", 1/2", 5/8", 3/4", and 7/8" soft tubing up to 90° using color-coded mandrels and a universal crossbar that makes size changes fast. The Deluxe Compact Bender Kit with Reverse Bending Attachment (SKU 1926598) adds outward-bend capability, enabling precise angle bends up to 90° in tight mechanical spaces where a standard bender won't reach. Both benders use metal mandrels and a quick-release mechanism, which means clean tube release without the contortion moves that plastic-mandrel benders typically require.

Flaring Tools

Hilmor flaring tools produce consistent 45° flares for HVAC refrigerant connections, covering installations from standard split systems to multi-zone mini-splits. The Hilmor Orbital Flare (SKU 1838952) uses an off-center mounted cone that spins on an axis to uniformly shape tubing from 3/16" through 3/4". A spring-loaded block grips the tube securely, a tube-stop arrow eliminates the guesswork of flare height positioning, and a built-in clutch mechanism stops the flaring process automatically when the job is done, reducing the risk of cracked tubes from over-driving. For contractors specifying flare connections on new A2L refrigerant systems, precise torque matters as much as flare geometry, which is why Hilmor's Digital Adjustable Torque Wrench (SKU 1963826) includes 9 memory settings of common flare nut torque values with both audible and visual indicators at target torque.

Swaging Tools

Hilmor swaging tools handle tube-to-tube connections without soldering, expanding tubing so two lengths can connect directly with a brazed joint. The Hilmor Compact Swage Tool (SKU 1839015) uses a hydraulic lever mechanism and one-handed release button to swage tubing from 5/16" up to 1-5/8" without splitting the tube, even at the smaller end of that range. The pistol-grip form factor fits in spaces where traditional swage tools can't operate. The Deluxe Compact Swage Tool Kit (SKU 1964041) steps it up with expander heads covering 1/4" through 1-5/8", plus a pocket-size deburring tool, making it a complete single-bag solution for most lineset connection work.

Vacuum Pumps

Hilmor vacuum pumps are two-stage rotary vane pumps available in 3, 5, 9, and 12 CFM to match system size and time-on-job targets. The 12 CFM model (SKU 1950532) runs on a 1 HP motor at 2550 RPM, pulls to an ultimate vacuum of 25 microns, accepts 1/4", 3/8", and 1/2" inlet tree fittings, and carries a 2-year limited warranty. All Hilmor vacuum pumps feature a forward-sloped oil reservoir for faster drainage, an oversized sight glass, an oversized oil fill port, and dual hoist points for shoulder-strap transport. Choosing CFM depends on system size: smaller residential systems typically work well with 3 or 5 CFM, while larger commercial installations or multi-zone systems may call for 9 or 12 CFM to keep evacuation times practical.

Manifold Gauges, Hoses, and Service Tools

Hilmor manifold gauges, refrigerant hoses, and service tools cover the measurement and connection side of HVAC/R service work. Hilmor aluminum manifolds are built with replaceable stainless steel valve seats, SAE-style O-rings, and a large sight glass for leak resistance over repeated use cycles. Refrigerant hoses include both standard and ball-valve options in vacuum-rated construction, with stainless steel evacuation hoses available for faster deep-vacuum pulls. Hilmor valve core removal tools come in 1/4" (SKU 1947967) and 5/16" sizes, each equipped with a built-in rare-earth magnet on the plunger so removed cores stay where a technician can find them instead of rolling off a condenser cabinet.

BUYING GUIDE / HOW TO CHOOSE

Selecting the right Hilmor HVAC tools starts with matching tool capability to the specific task category. For tube working, the first question is bend direction: standard installations typically use the Compact Bender Kit (SKU 1839032), while jobs in mechanical rooms or attic spaces with limited swing room benefit from the Compact Bender Kit with Reverse Bending Attachment (SKU 1926598), which handles outward bends on 1/4" to 7/8" tubing. For flaring, the choice between the Hilmor Basic Flare and the Orbital Flare (SKU 1838952) comes down to volume and accuracy requirements. The Orbital Flare's clutch stop and tube-stop arrow make it the stronger pick for mini-split work where A2L refrigerants raise the stakes on flare integrity. Pairing it with the Hilmor Digital Adjustable Torque Wrench (SKU 1963826) closes the loop on repeatable, spec-accurate flare connections. For vacuum pump selection, size the CFM to the system: a 3 or 5 CFM pump works for most single-zone residential calls, while a 9 or 12 CFM pump cuts evacuation time meaningfully on larger multi-zone or light commercial systems. The 12 CFM model (SKU 1950532) pulls to 25 microns with a 1 HP motor, which covers most commercial applications without reaching into industrial-grade hardware. For storage and transport, the Hilmor HVAC/R Tote (SKU 1839078) organizes up to 50 lbs. of tools across 27 pockets and 18 elastic bands, and the HVAC/R Refrigerant Tank Backpack (SKU 1891628) carries up to 30 lb. cylinders without a handcart. When stocking a service van for general residential and light commercial work, the Hilmor HVAC/R Starter Kit gives new techs a verified entry-level collection built around the same core Hilmor tool categories.

FAQs

What sizes does the Hilmor Compact Bender handle, and does it work for mini-split linesets?

The Hilmor Compact Bender Kit (SKU 1839032) bends 1/4", 5/16", 3/8", 1/2", 5/8", 3/4", and 7/8" soft tubing up to 90° using color-coded mandrels and a ratcheting one-handed mechanism. The size range covers the lineset diameters used in most residential and light commercial mini-split installations, and the compact form factor fits into the tight spaces those jobs often require. For situations where outward bends are needed, the Deluxe Compact Bender Kit with Reverse Bending Attachment (SKU 1926598) adds reverse-angle capability for the same tubing size range.

How does the Hilmor Orbital Flare differ from a standard block flaring tool?

The difference between the Hilmor Orbital Flare and a traditional block flare tool is the cone mechanism: the Orbital Flare (SKU 1838952) uses an off-center mounted cone that spins on an axis, distributing material uniformly rather than pressing from a single point. A built-in clutch stops the flare automatically when the correct geometry is achieved, reducing the risk of tube cracking from over-driving. Standard block flares rely on hand-feel and experience to stop at the right point, which can introduce inconsistency across a long day of connections.

What CFM vacuum pump do I need for a multi-zone mini-split installation?

The right CFM for a multi-zone mini-split installation depends on total system volume and acceptable evacuation time. Larger multi-zone systems, especially those with longer linesets, may pull faster and achieve target micron levels more reliably with a 9 or 12 CFM pump than a 3 or 5 CFM unit. Hilmor's 12 CFM Two-Stage Rotary Vane Vacuum Pump (SKU 1950532) pulls to an ultimate vacuum of 25 microns with a 1 HP motor and accepts 1/4", 3/8", and 1/2" inlet tree fittings. Always confirm system manufacturer evacuation specifications before selecting CFM, as some A2L refrigerant systems may carry specific requirements in their installation documentation.

What's the difference between the Hilmor Compact Swage Tool and the Deluxe Compact Swage Tool Kit?

The difference between the Hilmor Compact Swage Tool (SKU 1839015) and the Deluxe Compact Swage Tool Kit (SKU 1964041) is primarily head coverage and kit completeness. The standard Compact Swage Tool ships with 3/8", 1/2", 5/8", 3/4", and 7/8" expander heads, while the Deluxe kit covers 1/4" through 1-5/8" with ten heads total, plus a pocket-size deburring tool. Both use the same hydraulic pistol-grip mechanism and one-handed operation, and both can swage from 5/16" up to 1-5/8" without splitting the tube. Contractors doing a broader range of lineset sizes in a single day may find the Deluxe kit the more practical pick.

Does the Hilmor valve core removal tool work on both 1/4" and 5/16" service ports?

Hilmor valve core removal tools are available in two separate sizes: the 1/4" model (SKU 1947967) and a 5/16" model, each matched to the corresponding service port size. Both tools feature a built-in rare-earth magnet on the back of the plunger that holds the removed valve core in place during evacuation or change-out, preventing the core from getting lost on the job. Purchasing both sizes covers the full range of service ports found on residential and light commercial HVAC/R equipment.
