Purpose statement A set of line and hose removal tools designed to release and remove quick-disconnect fittings on fuel, heater and air-conditioning lines without damaging the coupling or surrounding components. Key benefits Speeds repairs: quickly releases stubborn quick-disconnect fittings so you can remove lines and hoses faster than prying by hand. Protects components: designed to engage the fitting correctly and minimize damage to lines, couplings and seals. Built to last: made from hard, durable materials that resist wear and exposure to common solvents encountered during vehicle service. Wide vehicle compatibility: suitable for use on both domestic and imported vehicles with quick-disconnect lines and other split couplings. Main functions and attributes Line removal function: place the tool against the line or fitting to release the locking mechanism and allow removal of the line or hose. Quick-disconnect heater hose removal: each quick-disconnect heater hose tool is manufactured from hard material to ensure strength and long service life. AC line repair tools: included tools are appropriate for repairing and servicing automotive air-conditioning lines and related quick-disconnect fittings. Material and durability: constructed from solvent-resistant, durable material to withstand repeated use and exposure to repair-shop chemicals. Compatibility: usable on a variety of lines and disconnect couplings found on both domestic and imported vehicles. How to use (concise) Position the tool against the quick-disconnect fitting or line. Apply steady pressure to disengage the locking ring or clip. Withdraw the line or hose once the fitting has been released. Practical applications (use scenarios) Removing a heater hose quick-disconnect at the firewall during a coolant system repair on a passenger car. Disconnecting fuel or vapor lines from quick-connect couplings when servicing fuel injectors or fuel filters. Separating air-conditioning lines or service port fittings during AC compressor or condenser replacement on domestic and imported vehicles. What makes this set stand out Purpose-built for quick-disconnect fittings on fuel, heater and AC lines. Durable, solvent-resistant construction for reliable, repeatable performance. Suitable for professional workshops and DIY mechanics who need a safe, efficient method to remove lines without damaging fittings.
