POLIWELL AC Flush Kit for Car & HVAC Lines — 59" Nylon Hose, Stainless Steel Bottle, Flush Gun

The POLIWELL AC Flush Kit is a portable, reusable system for cleaning automotive and HVAC refrigerant lines using a 59-inch nylon hose, stainless steel flush bottle, and a rubber-tipped flush gun (solvent not included).

This professional-grade kit is built to clear old refrigerant, oil residue, and debris from car AC lines, condensers, and evaporators as well as many household refrigeration lines. It assembles quickly and stores neatly in the included plastic case. Designed for repeated use, the stainless steel bottle resists corrosion and holds pressures up to 150 PSI while the extra-long hose reaches deep or awkward plumbing runs found on trucks and SUVs.

How does the POLIWELL kit make flushing AC lines easier?

The kit combines a long, flexible hose with an ergonomic flush gun and quick adapters so you can reach and control flow into confined spaces. A built-in pressure monitoring system gives immediate feedback while an adjustable relief vent reduces the risk of over-pressurizing the bottle.

• 59.1-inch nylon hose extends access for undercarriage and large-vehicle lines.
• Rubber-tipped flush gun improves sealing and directional control of solvent.
• Dual-gauge dial shows bottle pressure in real time for safer flushing.
• Relief vent automatically vents excess pressure to protect the bottle.

What vehicles and systems work with this flush kit?

This kit is compatible with a wide range of automotive refrigerants and can be used on air conditioning lines, condensers, evaporators, and many refrigeration lines in residential systems. It’s especially helpful for SUVs, light trucks, and vehicles with long or hard-to-reach piping.

• Compatible with R134a, R12, R22, R404a, R406a, R410a refrigerants.
• Long hose covers extra-length lines found in larger vehicles.
• Adapters provided to fit common service ports and 1/4" fittings.
• Also suitable for condenser and evaporator circuit cleaning in HVAC units.

How durable and maintainable is the system?

The flush bottle is formed from a single piece of stainless steel to resist leaks, rust, and repeated washouts. Replacement parts and adjustment tools are included so you can keep the kit operational without needing full replacements after routine use.

• Stainless steel body rated to withstand up to 150 PSI.
• Corrosion-resistant design for long service life and repeated cleaning.
• Includes spare seals, fittings, and adjustment tools for field maintenance.
• Washable interior for multiple solvent cycles and reuse.

What safety and control features are included?

Built-in monitoring and a mechanical relief vent help manage internal pressure during flushing so you can maintain controlled flow, reducing risk while working with pressurized solvent lines. The flush gun’s rubber tip helps form a tight seal to direct cleaning fluid where needed.

• Dual-gauge dial for monitoring internal pressure at a glance.
• Adjustable relief vent automatically releases excess pressure.
• Sealed rubber tip on the gun reduces spray and improves accuracy.
• Plastic storage case secures components and prevents damage in transit.

Who is this for: The POLIWELL AC Flush Kit is suited for automotive technicians, DIY mechanics, fleet maintenance crews, and HVAC professionals who need a portable, reliable tool to flush refrigerant lines and related components. It’s particularly useful for anyone working on larger vehicles or long piping runs who needs extended reach, solid pressure control, and a durable, reusable bottle that stands up to repeated service cycles.
