Inhouse product
Manifold gauges for HVAC systems typically include two large gauges (high/low side), a central manifold block, and three color‑coded hoses (blue low‑side, red high‑side, yellow service hose).
Sets compatible with R410A, R22 and R404A refrigerants have robust gauges rated for high pressures and standard 1/4″ SAE connections.
Professional sets often have 60″ hoses for easy access to outdoor units and service valves.
