Manifold Gauge Replacement Gauges and Boots

This category features commercial-grade manifold gauge replacement gauges and protective boots engineered to maintain the calibration accuracy and structural durability of professional HVAC/R diagnostic testing manifolds. The selection includes high-accuracy replacement pressure gauges—featuring clear color-coded dials for specific high- and low-side pressure ranges, temperature pressure charts for modern low-GWP and high-pressure refrigerants, and flutter-free internal movements—alongside rugged, shock-absorbing rubber or silicone protective boots. Built to withstand frequent mechanical impacts, severe vibration, and harsh job-site environments, these replacement components allow technicians to repair damaged instruments without replacing the entire manifold assembly. This technical inventory provides certified HVAC/R technicians, refrigeration engineers, and mechanical contractors with the precise, code-compliant components required to ensure accurate system pressure monitoring, reliable leak testing, and long-term diagnostic equipment integrity.
