CraftyDream HVAC Valve Core Tool Kit — Dual‑Head Service Set, R22–R410 Compatible, 270 O-rings

CraftyDream Dual Head HVAC Valve Core Remover and Service Wrench Set is a complete refrigeration service kit that removes and installs valve cores, adapts to common refrigerants, and supplies O-rings, seals, magnetic pickup tools and inspection mirrors for professional HVAC maintenance.

This multi-piece set bundles a dual-size valve core tool, two curved HVAC service wrenches with hex bit adapters, a broad assortment of O-rings and compressor port seals, multiple magnetic pickup rods, and inspection mirrors so you can perform routine refrigerant valve work and fast hardware retrieval without hunting for parts. Components are made from brass, chrome carbon steel and durable plastics to balance corrosion resistance and strength for field use.

Which refrigerant systems and valve sizes does this kit work with?

The dual head valve core tool and included brass adapter support the most common residential and light-commercial refrigerants and valve sizes. It fits 1/4" and 5/16" ports and is compatible with R22, R12, R407, R410, R404 and R32 service ports. That broad compatibility reduces trips to the parts bin when switching systems.

• Dual head supports 1/4" and 5/16" valve cores
• Brass adapter for secure seating on service ports
• Compatible with R22, R12, R407, R410, R404, R32
• Not intended for automotive A/C valve cores

How does the wrench and adapter setup speed repairs?

The set includes two stainless/chrome carbon steel HVAC service wrenches with curved handles for access in tight spaces plus two hex bit adapters that lock in place. The curved grip and integrated bit adapters let you apply consistent torque in cramped service panels, speeding valve maintenance tasks and reducing slippage.

• Two multi-size wrenches covering 1/4", 3/8", 3/16", 5/16" needs
• Hex bit adapters with bead structure to prevent drop-out
• Curved handles for better reach and ergonomic leverage
• Durable chrome carbon steel construction for repeated use

What consumables and retrieval tools are included for a one-trip repair?

This kit is stocked for common refreshes and emergency fixes: 270 O-rings across 18 sizes and 60 compressor port seal washers in nine sizes cover frequent sealing needs, while 20 spare valve cores and multiple brass nuts handle replacements. Magnetic pickups in four pull strengths and two inspection mirrors mean you can find and retrieve lost fasteners and visually inspect hidden fittings without additional tools.

• 270-piece O-ring assortment (18 sizes) and 60-piece gasket seals (9 sizes)
• 20 valve cores plus two brass nuts for immediate replacements
• Magnetic pickup rods (1.5 lb, 3.5 lb, 10 lb, 15 lb) for retrieving metal parts
• Round and square inspection mirrors to view hard-to-see joints

How durable and portable is the CraftyDream service set?

Key components use brass for corrosion resistance and chrome carbon steel for strength; mirrors and magnetic tools use sturdy plastics and metal for everyday shop and field use. The variety and finish of parts are chosen to resist common refrigerant and workshop exposure while remaining light enough to carry in a technician bag.

• Brass valve tool resists corrosion on refrigerant ports
• Chrome carbon steel wrenches provide tensile strength and longevity
• Mirrors and magnetic tools built for repeated field handling
• Complete kit organized to minimize additional part purchases

Who is this for: HVAC technicians, maintenance professionals, and skilled DIYers who service residential or light commercial air conditioning systems and want a single, portable kit that covers valve core replacement, common seals, and hard-to-reach retrieval and inspection tasks. Note: not designed for automotive A/C systems; check port sizes before use.
