Direct-Fit Block Type Auto AC Expansion Valve OEM 88515-58010 for Toyota Lexus R134a TXV

The Silk TXV-88515-DB is a precision-engineered block type thermal expansion valve (TXV) designed for direct-fit replacement in Toyota and Lexus vehicle air conditioning systems. Manufactured to exact OEM specifications, this expansion valve delivers accurate refrigerant metering across the full range of operating conditions, ensuring stable evaporator superheat control and consistent cabin cooling performance. The forged brass body provides exceptional structural integrity under high-pressure cycling, while the stainless steel diaphragm assembly maintains precise responsiveness over thousands of thermal cycles. Unlike universal-fit alternatives that require field modifications, this direct-fit TXV matches the original mounting geometry, inlet/outlet port sizing, and calibration settings of factory-installed components on popular Toyota platforms including Camry, Corolla, RAV4, and Lexus ES and RX series. Every unit undergoes rigorous flow-rate calibration on automated test benches before leaving our ISO 9001 and TS 16949 certified production facility, guaranteeing that each valve meets or exceeds the performance benchmarks established by the original equipment manufacturer. For automotive parts distributors, independent repair shops, and fleet maintenance operations seeking reliable aftermarket AC components, this expansion valve represents an optimal balance of OEM-grade quality and competitive value.

• Direct-Fit OEM Compatibility: Engineered as a drop-in replacement for Toyota and Lexus vehicles utilizing OEM part numbers 88515-58010, 88515-42010, and 88515-0W010, with exact pad-mount bolt pattern alignment and pre-calibrated superheat settings that require no field adjustment during installation.
• Forged Brass Body Construction: The valve body is machined from high-density forged brass stock, providing superior resistance to corrosion, vibration fatigue, and thermal expansion stress compared to cast aluminum alternatives commonly found in budget aftermarket TXVs.
• Stainless Steel Diaphragm Assembly: The sensing diaphragm and pushrod mechanism utilize food-grade 304 stainless steel, delivering consistent actuation force across a wide temperature range from -40°C to +120°C without elastic degradation or hysteresis drift over the component lifespan.
• Precision-Calibrated R134a Orifice: The internal orifice plate is laser-drilled and flow-bench calibrated specifically for R134a refrigerant properties, achieving a nominal capacity of 1.5 tons with superheat control accuracy within ±1°C under standard SAE J2767 test conditions.
• Multi-Port Pad Mount Interface: Features a standardized four-port flange configuration with #6 liquid inlet, #8 suction inlet, #10 liquid outlet, and #12 suction outlet sizing, compatible with OEM hard-line and hose assemblies without adapter fittings or reducer bushings.
• 100% Production-Line Testing: Every unit is individually tested for internal leakage, external leakage, opening superheat setpoint, and nominal capacity before packaging and shipment, with serialized test records maintained for full batch traceability.
• Wide Vehicle Platform Coverage: One SKU covers multiple high-volume Toyota and Lexus models across several production years, reducing inventory complexity for distributors while maximizing parts turnover rates.

This block type expansion valve is engineered for direct-fit installation on a broad range of Toyota and Lexus passenger vehicles equipped with R134a air conditioning systems. Primary vehicle applications include Toyota Camry (XV40, XV50 series, model years 2006 through 2017), Toyota Corolla (E140, E170 series), Toyota RAV4 (XA30, XA40 series), Toyota Highlander (XU40, XU50 series), Toyota Avalon (XX30, XX40 series), and Lexus ES 350 (XV40, XV60 series) as well as Lexus RX 350 (AL10, AL20 series). Always verify fitment against the vehicle VIN and existing OEM part number before ordering. Cross-reference OEM part numbers include 88515-58010, 88515-42010, 88515-0W010, 88515-33060, and 88515-07010. The valve is suitable for both original equipment replacement and aftermarket AC system repairs performed by professional automotive technicians. Its calibrated R134a metering characteristics also make it appropriate for retrofitted systems originally designed for R12 refrigerant, provided the system has been properly flushed, evacuated, and recharged with compatible PAG compressor oil.

Each expansion valve is individually sealed in an anti-static poly bag with desiccant pack to prevent moisture ingress during transit and storage, then placed in a custom-fitted inner box with die-cut foam cushioning that isolates the valve body from external impact forces. Inner boxes are packed into export-grade five-layer corrugated master cartons, with each carton holding 50 units and featuring reinforced corner posts for stacking strength during ocean freight. Every production batch is accompanied by a certificate of conformance documenting the test results for opening superheat, internal leakage rate, and rated capacity. We maintain full batch traceability with serial-numbered test records archived for a minimum of three years. Our quality management system is certified to ISO 9001:2015 and IATF 16949:2016 standards, and all expansion valve products comply with SAE J2767 and IMACA 300 testing protocols. We offer a standard 12-month warranty against manufacturing defects from the date of shipment, with extended warranty options available for volume contract customers. Neutral packaging and private-label branding services are available upon request for distributors seeking to market under their own brand identity.
