CMTOOL AC Flush Kit - Stainless Steel Canister for Auto & Home HVAC

Premium AC flushing with the CMTOOL kit

Meet the CMTOOL AC Flush Kit, built around a thickened stainless steel canister designed to stand up to repeated use. The canister's solid body helps minimize leaks and deliver consistent air flow, making it a dependable choice for cleaning automotive A/C lines and indoor HVAC components. The 1-liter capacity is ideal for many washing tasks, reducing the need for frequent recharges during a session.

Every kit ships with carefully chosen components: a 3.5-foot charging hose with brass fittings, a pressure gauge, a rubber-tipped flush head, and hoses with 1/4 inch fittings, plus spare adapters, O-rings, and gaskets. These elements work together to provide a reliable, long-lasting tool set that can be assembled quickly and used with most standard air compressors (not included).

Durability, safety, and versatility

The stainless steel canister is corrosion-resistant, and the overall assembly is designed for reuse. The 600 PSI maximum working pressure rating on the hose and the 150 PSI recommended working pressure let you work within safe limits while delivering sufficient airflow for flushing tasks. The kit is compatible with common refrigerants used in automotive and home HVAC systems (R134A, R12, R22, R404A, R410A), making it a versatile solution for various projects.

• Sturdy stainless steel construction reduces leaks and improves longevity.
• Corrosion-resistant design supports repeated use in tough environments.
• 3.5 ft hose and brass fittings provide flexible, durable connections.
• 1 L canister capacity balances workload and refill needs.

What’s included and how to use

The packing list covers every essential piece: 1 stainless steel canister, 1 pressure gauge with 1/4" NPT adaptor, 1 flush head with a rubber tip, 1 hose with 1/4" fittings, and two spare adapters plus O-rings and gaskets. To use, fill the canister with your chosen AC flush material, tighten the fittings, connect to your air compressor, then open the valve and operate within the recommended pressure. This simple workflow helps you clean clogged pathways and surfaces without disassembly.

Real-world scenarios

Techs and DIY enthusiasts will appreciate how the kit makes routine A/C maintenance easier: preparing a car for warmer seasons, clearing buildup in home HVAC lines, or refreshing a clogged condenser line during service calls. The kit's reach and build quality support comfortable, controlled work in tight spaces or overhead installations.
