KAISAL AC Flush Kit Stainless-Steel Pressurizable Canister with 3.5ft Hose & Pressure Gauge

KAISAL AC Flush Kit is a stainless-steel pressurizable canister system for safely flushing refrigerant oil and debris from air-conditioning lines, condensers and evaporators while monitoring pressure in real time.

Designed for HVAC technicians and DIYers replacing compressors or servicing AC systems, this kit combines a thickened stainless-steel bottle, a readable pressure gauge, an adjustable pressure relief valve and a corrosion-resistant spray head to deliver controlled solvent flushing. The unit accepts lightweight flushing solvents (not included), connects to a shop air supply, and uses a steel draft tube and high-strength hose to maintain a steady flow without kinking.

How does the pressure regulation and safety system work?

The KAISAL kit includes an adjustable pressure-relief valve plus a visible gauge so you can set and watch the bottle pressure while flushing. The relief valve can be tightened or loosened with a hex wrench to change the release setting; it automatically vents if pressure rises above the safety threshold to prevent over-pressurization.

• Adjustable relief valve for customized working pressure (do not exceed 150 PSI)
• Automatic release above approximately 170 PSI for added protection
• Clear analog pressure gauge for continuous monitoring

What components are included and how do they improve flushing performance?

The kit pairs a heavy-duty stainless-steel bottle with a steel draft tube and electroplated spray head to resist corrosion and avoid flow restrictions. A 3.5 ft reinforced hose and fittings let you reach condensers or evaporators while the hook provides hands-free hanging during service. These parts are chosen to minimize leaks and ensure consistent solvent delivery.

• Thickened stainless-steel canister for leakproof, corrosion-resistant use
• Steel draft tube to prevent kinks and maintain solvent flow
• Electroplated spray head with rubber tapered nozzle for a tight pipe seal
• 3.5 ft hose with 600 PSI working pressure and 3000 PSI burst rating

Which systems and situations is this flush kit suitable for?

The KAISAL flush kit works with many closed-loop HVAC systems and short refrigeration lines where solvent flushing is appropriate. Typical uses include removing old refrigerant oil, sludge and debris before installing a replacement compressor or after component failures, as well as cleaning condensers, evaporators and vehicle AC pipes.

• Residential and light-commercial air-conditioning lines and coils
• Automotive AC pipes, condensers and evaporators
• Household refrigerator/AC small-pipe cleaning tasks
• Not a refrigerant charging tool—refrigerants and solvents sold separately

How easy is the kit to operate and maintain during a service job?

Operation is straightforward: fill the canister with an approved lightweight flushing solvent, pressurize with a shop air connection, then use the spray head and hose to flush system sections. The built-in hook, readable gauge and sturdy fittings simplify single-person work and reduce the risk of spills or interruptions during a procedure.

• Fill vessel, attach to compressor air supply (air compressor not included)
• Monitor gauge and control flow with the spray head nozzle
• Hang canister using the integrated hook for hands-free use
• Steel construction makes cleaning and inspection simple and durable

Who is this for? The KAISAL AC Flush Kit is aimed at professional HVAC technicians, automotive service shops and knowledgeable DIYers who regularly service air-conditioning or refrigeration circuits and need a durable, pressure-monitored flushing tool. It’s especially useful when replacing compressors, clearing oil contamination or preparing lines for retrofitting. Note: always follow solvent manufacturer instructions and local regulations; refrigerants and cleaning fluids are not included.
