RALBIL AC Flush Kit 3.5ft Hose — Stainless HVAC Flushing Kit with Dual-Scale Gauge & Adjustable Relief Valve

RALBIL AC Flush Kit is a portable HVAC cleaning system that pressurizes and rinses air-conditioning lines with real-time pressure readout for safe, efficient flushing of R134a, R410a, R22, R12 and R404 systems.

Whether you're servicing a car, household refrigerator, or a home air handler, this kit gives you a controlled, reusable way to clear oil, debris, and contaminants before repairs or system changes. The set combines a durable stainless-steel solvent bottle, a dual-unit pressure gauge, an adjustable relief valve and a 1-meter (3.5 ft) rubber hose with workshop-air hookup for fast flushing operations.

How does the RALBIL kit keep flushing safe and controlled?

The kit's built-in dual-unit gauge displays pressure in two scales so you can monitor bottle pressure at a glance and maintain the ideal working range. A pressure relief valve lets you fine-tune output—tighten to raise pressure, loosen to lower it—and it vents automatically above 170 PSI (12 kg) to prevent over-pressurization.

• Dual-scale gauge for PSI and bar readings.
• Adjustable air relief valve with 170 PSI auto-release.
• Works with regulated shop air for repeatable results.

Which systems and refrigerants can this flush kit handle?

Designed for broad HVAC and automotive use, the RALBIL flush kit is compatible with common systems and refrigerants used in vehicles and household appliances. It’s intended for line and component flushing—evaporators, condensers, pipes and compressor-related parts—prior to replacement or after contamination.

• Compatible with R134a, R410a, R22, R12, R404 and similar refrigerants.
• Suitable for automotive AC lines, home AC piping, condensers and evaporators.
• Used with user-supplied AC flushing solvent and shop air source.

What makes the construction durable and user-friendly?

The canister is fabricated from thickened stainless steel to resist corrosion, leaks and heat while standing up to repeated workshop use. A 3.5-foot rubber hose balances flexibility with pressure resistance for accessing tight spaces, and the included portable hook allows hands-free positioning during longer flush cycles.

• Thick stainless-steel bottle resists corrosion and leakage.
• Approximately 1-meter rubber hose with high working and burst pressure ratings.
• Convenient hook for hanging and stable operation in cramped areas.

How easy is it to operate and maintain over time?

Operation is straightforward: fill the bottle with an approved flushing solvent (not included), attach the hose and gauge assembly, then pressurize using workshop air. The kit is reusable and made for years of routine maintenance; replaceable parts and a 3-year product service promise simplify long-term ownership.

• Simple fill-connect-pressurize workflow with no complex tools required.
• Designed for repeated use; replaceable components if needed.
• 3-year product service for parts and product issues.

Who is this for? HVAC technicians, independent auto mechanics and knowledgeable DIYers who perform routine or pre-repair cleaning of AC systems will find this kit useful. It’s best for people who already have a compatible shop air supply and appropriate AC flushing solvent, and who need a portable, pressure-controlled tool to clear refrigerant lines, condensers and evaporators before component replacement or system reassembly. The RALBIL kit gives a balance of durable construction, pressure monitoring and practical accessories for consistent flushing performance.
