CMTOOL AC Flush Kit is a reusable stainless-steel canister kit that lets technicians and DIYers safely flush automotive and home HVAC systems using compressed air and a light flushing solvent.

The CMTOOL AC Flush Kit pairs a thickened stainless canister with a durable hose, brass fittings and spare adapters so you can clear lines, evaporators, condensers and hard-to-reach passages on R134A, R12, R22, R404 and R410A systems. Built for repeated use, the tool is pressure-rated for routine shop flushing when paired with a compatible compressor and solvent (solvent not included). The kit is compact enough for mobile work yet robust for professional garage or HVAC shop use.

How does this kit help clear contaminants from an A/C or HVAC line?

The kit pressurizes a light flushing solution inside the stainless canister and forces fluid and trapped debris through coils, tubes or fittings. The high-pressure structure and tapered flush head enable targeted bursts that dislodge sludge, oil residue and particulates that reduce cooling performance.

  • Thickened stainless steel canister resists pressure and contamination.
  • Tapered rubber flush head reaches into fittings and ports.
  • 3.5 ft rubber-nylon hose withstands heat and abrasion for reliable flow.
  • Spare adapters let you connect to common SAE and NPT service ports.

What pressure limits and safety steps should I follow?

Operate the kit with an air compressor but never exceed the recommended working pressure—150 PSI during flushing—to avoid overpressurizing seals. The canister and fittings are rated higher, but safe flushing uses controlled pressure and proper PPE.

  • Maximum working pressure for the hose: 600 PSI; recommended flush pressure: ≤150 PSI.
  • Burst pressure ratings are high, but use regulator and gauge to control flow.
  • Wear eye protection and gloves; vent flushed solvent and debris per local rules.

Which parts and adapters are included, and how do they make the kit versatile?

The kit comes complete with the stainless canister, a pressure gauge with American air plug, multiple adapters, spare O-rings and a rubber-tipped flush head so you can service a wide range of vehicle and HVAC fittings without hunting for extras. Spare seals and gaskets help maintain a leak-free setup between services.

  • 1L stainless canister built for repeated compressed-air use.
  • Pressure gauge with 1/4" NPT American plug and 1/4" SAE hose adapter.
  • Extra 1/4" SAE and 1/4" NPT adapters plus spare O-rings and gaskets.
  • 3.5 ft rubber nylon hose and rubber-tapered flush head for targeted cleaning.

Who is this for? The CMTOOL AC Flush Kit is aimed at professional mechanics, mobile A/C technicians and informed DIY homeowners who perform system maintenance on automotive or small commercial HVAC units. It suits users who already handle refrigerant service and compressed-air equipment and need a durable, reusable flushing canister with common fittings and spare parts for on-the-job versatility. Note: flushing solvents and compressors are not supplied; follow local environmental regulations when disposing of flush waste.
