It meters refrigerant flow into the indoor coil, maintaining proper superheat across a range of load conditions. This kit is rated for R-454B refrigerant and covers nominal system capacities from 3.5 to 4.0 tons. The valve body measures approximately 3.73 inches in length, 3.34 inches in depth, and 2.95 inches in height, making it a compact, direct-fit component. Oxbox is a Trane brand, and this kit is manufactured to OEM specifications for use in residential and light-commercial coil and air handler applications. Licensed HVAC technicians perform this installation.\u003c\/p\u003e\n\u003cp\u003eThis TXV kit is intended for indoor coil and air handler installations where R-454B is the system refrigerant. It is appropriate for residential split-system air conditioners and heat pumps operating in the 3.5 to 4.0 ton range. The 5AYTXVH3A4248A has been identified as the specified TXV kit for Oxbox and Trane systems using R-454B refrigerant at this capacity range, including configurations such as the 3.5 ton 14.3 SEER2 split-system platform that incorporates this valve as part of a complete metering device installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRated for R-454B refrigerant, compatible with current low-GWP system requirements\u003c\/li\u003e\n  \u003cli\u003eCovers 3.5 to 4.0 ton nominal system capacity\u003c\/li\u003e\n  \u003cli\u003eCompact valve body: 3.73 inches long, 3.34 inches deep, 2.95 inches tall\u003c\/li\u003e\n  \u003cli\u003eDesigned for evaporator-side installation in coils and air handlers\u003c\/li\u003e\n  \u003cli\u003eOEM-specified kit from Oxbox, a Trane brand\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Oxbox and Trane indoor coil and air handler systems rated at 3.5 to 4.0 tons and using R-454B refrigerant.
