Valve core installation and removal tools are specialized tools for installing and removing valve cores in air conditioning and refrigeration systems. Their core advantages are refrigerant-resistant and adaptable to tight spaces. Constructed from corrosion-resistant brass or stainless steel, the clamping end precisely fits the valve core structure of the AC unit, preventing slippage and damage to the valve core or seal. Key selling points address the needs of AC maintenance: they adapt to mainstream valve core models for high and low-pressure AC lines, eliminating the need for additional adapters. Their slim head allows access to densely packed areas of AC outdoor unit piping. Select models feature a non-slip rubber handle for effortless grip and a slip-resistant feel. They are suitable for valve core replacement and maintenance in residential and commercial air conditioners and refrigeration units. Whether performing maintenance at an AC repair shop, during factory commissioning, or during emergency repairs, they effectively ensure installation and removal quality, maintaining system airtightness.
