Multi-Size Air Conditioning Service Wrench Full

This professional air conditioner wrench is tailor-made for HVAC technicians to install, tighten, disassemble and maintain split air conditioning copper pipe valve fittings. Three dedicated sizes cover 1P/1.5P, 2P/3P and 3P/5P air conditioner units, matching all mainstream copper pipe joint nuts. Crafted from thickened industrial steel with quenching and forging hardening treatment, the integrated multi-opening design combines open-end spanner, 12-point ring sockets and hex drive holes all in one single tool. It eliminates the need to carry multiple separate wrenches, drastically accelerating AC installation and repair work for HVAC shops, professional contractors and DIY maintenance workers. Three Sizes Cover All Household & Commercial AC Units Three independent wrench models for full compatibility: 1P/1.5P: Fits small residential air conditioners, suits 6–9mm copper pipe joints 2P/3P: Matches medium split AC units, fits 6–12mm copper pipe fittings 3P/5P: Designed for large air conditioners & mini-split systems, fits 6–16mm copper valves All common valve nut dimensions (12,14,17,19,22,24,27mm) are pre-machined on each wrench body. Heavy-Duty Forged & Quenched Thick Steel Construction The whole wrench blank adopts solid forging and high-temperature quenching hardening technology. Thickened steel plate improves structural rigidity, resisting bending, deformation and wear under repeated heavy torque. The matte anti-rust surface withstands oil, moisture and long-term workshop use without rusting. All-In-One Multi-Opening Integrated Design Each wrench integrates open jaw spanner, multiple 12-point star ring sockets and internal hex drive holes in one piece. The serrated inner wall of ring sockets locks tightly onto brass nuts without slipping, avoiding scratches and nut rounding during tightening/loosening. One tool handles all copper valve, flare nut and pipe joint operations. Laser Etched Clear Size Markings All size data, unit matching labels and copper pipe parameter specs are permanently laser engraved on the wrench body. Technicians can quickly identify the correct opening size at a glance, cutting down lookup time on busy job sites. Precise Tight-Fit Machining Every jaw and socket opening is precision CNC machined for perfect fit with standard AC brass flare nuts. Full contact surface distributes torque evenly to prevent nut sliding, stripping or valve thread damage, protecting expensive air conditioner copper pipe assemblies. Application Scenarios Installation, disassembly and routine maintenance of split air conditioning indoor & outdoor units Tightening and loosening copper pipe flare valve nuts, refrigerant pipeline joints Residential household AC repair, commercial mini-split system service HVAC contractor daily field work, appliance repair shop tool kit supplement
