This component acts as a vital metering device that controls the amount of liquid refrigerant entering the evaporator coil. By facilitating the specific pressure drop necessary for the refrigerant to expand and absorb heat, it ensures your living space stays consistently cool. A clogged or restricted expansion tube can lead to poor cooling performance, frost buildup on the indoor coils, or unnecessary strain on the compressor.\u003c\/p\u003e\u003cp\u003eManufactured to exact LG specifications, the AJR69405502 is built with durable, high-grade copper and brass to withstand high-pressure environments and temperature fluctuations. Its precision-engineered internal diameter ensures the refrigeration cycle stays perfectly balanced, maximizing energy efficiency and extending the overall life of your air conditioner.\u003c\/p\u003e\u003cstrong\u003eInstallation \/ Replacement Instructions:\u003c\/strong\u003e\u003col style=\"list-style:none;padding-left:0;margin-left:0;\"\u003e\n\u003cli\u003eThis repair involves the sealed refrigeration system and must be performed by a licensed HVAC professional.\u003c\/li\u003e\n\u003cli\u003eRecover the refrigerant from the system into a certified container according to environmental regulations.\u003c\/li\u003e\n\u003cli\u003eIdentify the location of the expansion tube, typically found in the liquid line leading to the evaporator.\u003c\/li\u003e\n\u003cli\u003eCarefully cut or unsolder the old AJR69405502 tube from the copper piping.\u003c\/li\u003e\n\u003cli\u003ePosition the new expansion tube correctly and braze it into place using an inert gas to prevent internal oxidation.\u003c\/li\u003e\n\u003cli\u003ePerform a pressure leak test, evacuate the system with a vacuum pump, and recharge with the specified amount of refrigerant.\u003c\/li\u003e\n\u003cli\u003eCompatible with select LG residential and commercial air conditioning units, this OEM-quality expansion tube is essential for restoring peak thermal exchange performance.\u003c\/li\u003e\n\u003c\/ol\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003col style=\"list-style:none;padding-left:0;margin-left:0;\"\u003e\n\u003cli\u003eAC Expansion Tube – part number AJR69405502\u003c\/li\u003e\n\u003cli\u003eRegulates refrigerant flow for efficient heat absorption\u003c\/li\u003e\n\u003cli\u003eHelps prevent evaporator icing and compressor strain\u003c\/li\u003e\n\u003cli\u003eHigh-grade copper construction for long-term durability\u003c\/li\u003e\n\u003cli\u003eCompatible with select LG air conditioning systems\u003c\/li\u003e\n\u003cli\u003eOEM-quality part for reliable pressure regulation\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"LG","offers":[{"title":"Default Title","offer_id":39675862122675,"sku":"AJR69405502","price":127.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0523\/4003\/1667\/products\/imageDisplay_b7686eed-a04a-4b4b-b0ae-f3d42c92b852.jpg?v=1704732985","url":"https:\/\/lgparts.com\/products\/ajr69405502-air-conditioner-expansion-tube","provider":"LG Parts","version":"1.0","type":"link"}
