LG Diaphragms

Overview

The LG 5211a31002a is a capillary tube assembly used to meter refrigerant flow within a refrigeration or air conditioning system. The capillary tube acts as a fixed metering device, restricting refrigerant as it passes from the high-pressure side to the low-pressure side of the refrigerant circuit. This assembly is an OEM-spec replacement component installed by licensed HVAC-R technicians during system servicing or refrigerant circuit repair. It maintains proper pressure differential between the condenser and evaporator, which is essential for efficient system operation. Capillary tube assemblies are found in a range of residential and light commercial refrigeration and air conditioning equipment. This LG part is designed for use in systems where a fixed-orifice metering device is specified rather than a thermostatic expansion valve. Typical applications include window air conditioners, mini-split systems, and compact refrigeration units. Installation is performed when the original tube is kinked, blocked, or damaged and must be replaced to restore proper refrigerant metering.
