KAISAL AC Flush Kit — Stainless Canister with 3.5 ft Hose, Pressure-Regulating Valve & Gauge

KAISAL AC Flush Kit is a pressurized stainless-steel canister system for safely flushing air-conditioning and refrigeration lines, featuring a pressure-regulating/relief valve, readable gauge, spray head, hook and a 3.5 ft hose.

This professional-grade AC cleaning kit is built to remove old refrigerant oil, debris and contaminants from air-conditioning pipes, condensers and evaporators before compressor replacement or system retrofit. The set combines a durable, thickened stainless bottle and steel draft tube with a pressure relief feature and a clear gauge so you can control and monitor the flushing process with shop air. It works with lightweight AC flushing solvent (not included) and standard shop compressors.

How does the pressure-regulating and relief valve improve safety?

The integrated valve lets you set the flushing pressure you need and automatically vents if pressure rises above the safety threshold, protecting the bottle and components. Adjustment is made with a hex wrench (not included) so you can fine-tune the release point for the job at hand.

• Adjustable relief valve — tighten to increase, loosen to decrease pressure.
• Automatic relief above ~170 psi (approx. 12 kg) for fail-safe protection.
• Recommended working pressure: do not exceed 150 psi.
• Clear gauge shows internal bottle pressure in real time.

What makes this kit suitable for different AC and refrigeration systems?

The KAISAL kit is compatible with a wide range of systems — vehicle AC pipes, household refrigerator lines, condensers and evaporators — because it cleans with solvent under controlled air pressure rather than specialized refrigerants. The spray head’s sealed nozzle prevents back-spray, and the steel draft tube resists collapsing for reliable flow.

• Works with lightweight AC flush solvents (solvent and compressor sold separately).
• Rubber-tapered spray head seals various pipe openings to prevent splatter.
• Steel draft tube eliminates kinks and maintains steady solvent delivery.
• Electroplated spray head resists rust and simplifies long-term use.

How does the kit handle durability and leak prevention during heavy use?

Durability was prioritized with a thickened stainless-steel bottle and robust hose rated for high working pressures. Seals and metal fittings reduce leak risk, while the hose’s rated burst strength gives confidence when pressurizing the canister for a thorough flush.

• Upgraded stainless-steel canister resists corrosion and pressure leaks.
• 3.5 ft hose with 600 psi working pressure and up to 3000 psi burst tolerance.
• Steel fittings and metal draft tube reduce wear from repeated use.
• Hook design lets you hang the canister for hands-free operation during procedures.

What do I need to use the KAISAL AC Flush Kit effectively?

Set up requires common shop equipment and a suitable cleaning solvent. You’ll need an air compressor and a hexagon wrench to set the pressure relief valve, plus a lightweight AC flushing solvent matched to your system. Refrigerants are not used in this flushing step and are not included.

• Required: air compressor (not included) to pressurize the canister.
• Required: lightweight AC flushing solvent (not included).
• Tool: hexagon wrench (not included) to adjust the relief valve.
• Recommended: protective gloves and eye protection when flushing solvents.

Who is this for: The KAISAL AC Flush Kit is designed for professional HVAC technicians, automotive mechanics and knowledgeable DIYers who perform AC compressor swaps, system retrofits or regular maintenance. It suits anyone who needs a durable, pressure-monitored flushing tool to remove oil residue and debris from air-conditioning and refrigeration lines before reassembly or servicing. For safe, reliable results follow solvent manufacturer guidelines and local disposal rules; for product concerns KAISAL offers a three-year service policy for non-human-damage defects.
