Shimeyao Refrigeration Filter Dryer 6-Pc Pack 1/4x1/4 Copper with Charging Valve — 9" Compact Liquid-Line Protection

This six-piece bundle provides technicians and DIYers with compact, service-ready filter dryers built from copper and fitted with charging valves. Each unit measures 1/4" x 1/4" with an overall length of 9" and a 4" body, making them suitable for confined installs and standard liquid-line protection. The internal molecular-sieve element captures moisture and particulates to help maintain system cleanliness and reduce the risk of corrosion or valve blockage over time.

How will these filter dryers fit into my refrigeration system?

These filter dryers use standard 1/4" flare/connection sizing and a slim 9" length, so they fit in tight liquid-line locations common in small air conditioning and refrigeration units. Confirm line size and mounting clearances before installing.

• Connection size: 1/4" x 1/4"—verify match to your service ports
• Body length: 4"—compact for limited space
• Overall length: 9"—allows room for charging valve access
• Copper construction—solderable or brazable for standard installation

Which refrigerants are these filter dryers compatible with?

Shimeyao units are compatible with a broad set of common refrigerants used in residential and commercial equipment when line sizes match. Always cross-check with system manufacturer recommendations.

• Works with: R12, R22, R502, R134a, R407C
• Suitable for most liquid-line applications matching 1/4" fittings
• Not a replacement for OEM-specified specialty media—verify application

What protection does the molecular sieve element offer?

The molecular-sieve core adsorbs moisture and traps particulates that can damage expansion valves, compressors, and other components. While it helps preserve system cleanliness, periodic replacement is recommended as part of routine maintenance.

• Adsorbs water vapor to minimize acid formation
• Filters solids and debris that cause valve clogging
• Helps protect downstream components and service life

How easy are these filter dryers to install and service?

Each unit includes a charging valve for convenient evacuation, charging, and pressure checks, and the copper body is compatible with common joining methods. Installation is straightforward for trained technicians; ensure proper brazing and leak testing afterward.

• Charging valve included for system access
• Copper shell allows soldering or brazing installation
• Designed for quick replacement during service calls
• Sold as a pack of six for multiple repairs or spares

Who is this for: This six-pack is aimed at HVAC technicians, refrigeration service shops, and experienced DIYers who need reliable, compact filter-drier units for small to medium systems. It's especially useful for fleets of units, preventive maintenance programs, or stocking common replacement parts for systems using 1/4" connections and compatible refrigerants. Always inspect system requirements and follow safe handling and installation procedures when working with refrigerants.
