Featuring a vibrant red casing for immediate high-side identification, this analog gauge provides a 0 to 500 psi working range. Designed with a 1\/8 inch MPT brass fitting, it is specifically calibrated for \u003cstrong\u003eHVAC manifold gauge sets\u003c\/strong\u003e managing R-12, R-22, and R-502 refrigerants. The internal breathing diaphragm is a critical technical feature that eliminates air bubbles for steady, accurate needle movement, while the temperature-compensated design ensures precision regardless of ambient fluctuations. Housed in a high-tensile Zytel casing, this \u003cstrong\u003ehigh side gauge\u003c\/strong\u003e resists impact and corrosion in demanding field environments. This non-illuminated, Class 1 instrument offers 1% accuracy across the entire dial, making it a reliable standard for technicians requiring a durable \u003cstrong\u003erefrigeration pressure gauge\u003c\/strong\u003e for legacy system service and maintenance.\u003c\/p\u003e\n\n\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrecise Scale Calibration:\u003c\/strong\u003e Rated for 0 to 500 psi with 1% accuracy, providing the reliable data required for critical system charging and diagnostics.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLegacy Refrigerant Compatibility:\u003c\/strong\u003e Dedicated scales for R-12, R-22, and R-502, optimized for older \u003cstrong\u003eHVAC system troubleshooting\u003c\/strong\u003e and maintenance.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnhanced Durability:\u003c\/strong\u003e The impact-resistant Zytel housing and internal seal prevent freezing and corrosive buildup within the \u003cstrong\u003eanalog pressure gauge\u003c\/strong\u003e.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSteady Readings:\u003c\/strong\u003e Equipped with a unique breathing diaphragm that prevents air pocket formation and needle flutter during high-pressure operation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\n\u003cp\u003e\u003cstrong\u003eIs this gauge compatible with R-410A systems?\u003c\/strong\u003e\u003cbr\u003e\nNo, the M2-875 is specifically calibrated for R-12, R-22, and R-502. Using it with higher-pressure refrigerants like R-410A may exceed the 500 psi limit and damage the internal calibration.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes this unit come with a protective gauge boot?\u003c\/strong\u003e\u003cbr\u003e\nThe standard M2-875 does not include a boot. For additional protection against job site drops, a separate 3-1\/8 inch gauge boot should be added.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat type of connection does this gauge use?\u003c\/strong\u003e\u003cbr\u003e\nIt features a standard 1\/8 inch MPT (Male Pipe Thread) brass fitting, allowing it to screw directly into most standard \u003cstrong\u003eHVAC manifold sets\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eDisclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
