Shimeyao Refrigerant Filter Drier 1/4" x 1/4" 25g — 6-Pack Copper Inline with Charging Valve, 9" Length

Shimeyao 6 Pcs Filter Drier is a copper-line liquid refrigerant filter and dryer—1/4" x 1/4", 25 g molecular-sieve core, supplied as a six-piece set for common AC and refrigeration systems.

This set of six directional filter driers is built for technicians and DIYers who need a compact, reliable inline component to remove moisture, trap particulates and help limit acid formation inside refrigeration and air-conditioning liquid lines. Made from copper with a 25-gram molecular sieve core and a 9" overall length (4" body), these driers are designed to work with many common refrigerants including R12, R22, R502, R134a and R407C. They include a charging valve on the line and are intended for straightforward soldered or brazed installation where size and compatibility match system requirements.

How do these filter driers protect my refrigeration system?

Filter driers are a sacrificial safeguard: they trap solid debris and absorb moisture that would otherwise circulate and cause corrosion, valve malfunction or oil degradation. By capturing contaminants and adsorbing water, they reduce the risk of component wear and help maintain refrigerant purity over time.

• 25 g molecular sieve core absorbs water and acids
• Captures particulates that can clog expansion devices
• Reduces corrosive byproducts that shorten compressor life
• Directional design ensures correct flow and performance

Which systems and refrigerants are these driers compatible with?

These Shimeyao driers fit systems that accept a 1/4" x 1/4" inline liquid filter drier with a 9" length and copper construction. They are suitable for many retrofit and service applications when the physical size and refrigerant match the system’s specifications.

• Compatible refrigerants: R12, R22, R502, R134a, R407C
• Ideal for small to medium residential and commercial lines that use 1/4" fittings
• Requires soldering or brazing to install—verify service port orientation
• Not for use if a larger capacity or different connection size is required

How do I install and service the Shimeyao filter drier?

Installation is straightforward for anyone competent with refrigeration piping: cut out the old drier, observe flow direction, properly braze the copper joints and leak-test the system. The integrated charging valve saves time during evacuation and recharge, but standard service best practices—evacuation, leak-check, and correct refrigerant charge—must be followed.

• Confirm flow direction stamped on the body before fitting
• Braze or solder using proper flux and techniques for copper tubing
• Evacuate the system fully before recharging refrigerant
• Replace when moisture or pressure-drop issues indicate saturation

What are the physical specs and package contents?

Each unit is a copper-bodied directional filter drier with a 25 g molecular sieve element, sized for 1/4" liquid line connections and a total length near 9" with about 4" main body. Units are sold as a pack of six, providing enough spares for multiple service calls or full-system servicing.

• Material: copper construction for standard refrigeration piping
• Size: 1/4" x 1/4" connections; approximately 9" total length, 4" body
• Core: 25 g molecular sieve desiccant
• Package: 6 filter driers per order, each with built-in charging valve

Who this is for: HVAC technicians, refrigeration service professionals, and experienced DIY installers who need a compact, economical inline liquid filter drier compatible with legacy and modern refrigerants. Choose these Shimeyao units when the system accepts 1/4" fittings and you want a practical six-piece supply for multiple installations or spare parts. Always verify system requirements and follow safe brazing and charging procedures during service.
