REAXOAL 3-Pack 25g Liquid-Line Filter Drier 1/4" x 1/4" with Charging Valve — Moisture & Particle Protection

REAXOAL 3 PCS Filter Drier is a compact liquid-line moisture and particle remover with an integrated charging valve, designed to protect refrigeration systems and simplify service.

This triple-pack of 25-gram liquid-line filter driers by REAXOAL includes a built-in charging valve and 1/4" x 1/4" flare fittings for straightforward inline replacement on small to medium refrigeration and air-conditioning circuits. Each unit traps moisture, captures solid contaminants, and helps prevent acid formation that can damage compressors and expansion devices. The lightweight design and common size make these filter driers a convenient spare-part solution for technicians and DIYers working with multiple refrigerants.

How does this filter drier protect a refrigeration circuit?

The REAXOAL filter drier adsorbs water vapor and filters out particulates that circulate in the liquid line. Removing moisture reduces the risk of ice or corrosion, while trapping solids prevents orifices and valves from clogging.

• Desiccant core removes moisture to lower corrosion and freeze risk
• Internal screens capture metal shavings and debris
• Helps limit acid buildup by removing water and contaminants
• Built-in valve allows service without breaking the entire system

Which systems and refrigerants is this compatible with?

These 25g filter driers are intended for liquid-line service on systems that accept 1/4" flare connections. They are suitable for a wide range of common refrigerants when the system specifications match the part size and capacity.

• Compatible with R12, R22, R502, R134a and R407C among others
• Best for small to medium residential and light commercial equipment
• Check system manufacturer requirements before installation
• Not rated for oversized industrial liquid lines without verification

How do you install and service the REAXOAL 25GR filter drier?

Installation is simple: cut the liquid line, remove the old drier, and flare the connections to the new 1/4" x 1/4" unit. The integrated charging valve lets you evacuate, charge, or test the circuit without adding extra service ports.

• Install in the liquid line downstream of the condenser
• Use proper brazing or flare technique per system requirements
• Valve permits convenient charging and pressure checks
• Replace if pressure drop increases or after major compressor failure

What should I look for when choosing a filter drier replacement?

Pick a drier that matches the system’s connection size, capacity needs, and approved refrigerants. Consider desiccant size (25 g here) for system volume and replace after contamination events or according to service schedules.

• Confirm 1/4" x 1/4" flare fittings match your piping
• Ensure refrigerant compatibility and sufficient desiccant mass
• Replace after compressor burnout to remove acid and debris
• Keep spare units for quick field service—sold here in a 3-piece pack

Who is this for: HVAC technicians, maintenance teams, and informed homeowners who need a compact, service-friendly liquid-line filter drier for small refrigeration and air-conditioning systems. If you maintain systems using common refrigerants like R134a or R22 and require an easy-to-install replacement with a charging valve for routine servicing, this REAXOAL 25GR 1/4" x 1/4" pack provides a practical, cost-effective option. Always verify compatibility with your equipment and follow safe refrigerant-handling procedures when installing or servicing.
