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.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these filter driers protect my refrigeration system?\u003c\/h3\u003e\n\u003cp\u003eFilter 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.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e25 g molecular sieve core absorbs water and acids\u003c\/li\u003e\n  \u003cli\u003eCaptures particulates that can clog expansion devices\u003c\/li\u003e\n  \u003cli\u003eReduces corrosive byproducts that shorten compressor life\u003c\/li\u003e\n  \u003cli\u003eDirectional design ensures correct flow and performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich systems and refrigerants are these driers compatible with?\u003c\/h3\u003e\n\u003cp\u003eThese Shimeyao driers fit systems that accept a 1\/4\" x 1\/4\" inline liquid filter drier with a 9\" length and copper construction.
