Marine manifold gauge sets are essential tools for monitoring and servicing refrigeration systems on boats. They measure pressure levels in both high and low sides of the system to ensure optimal performance. These gauges are designed to withstand harsh marine environments, providing accurate readings for maintenance and troubleshooting.

Size: Typically available in 1/4", 3/8", or 1/2" hose connections.

Grade: Designed for HVAC/R (Heating, Ventilation, Air Conditioning, and Refrigeration) applications.

Viscosity: Compatible with refrigerants like R-134a, R-404A, R-410A, etc.

Buoyancy: Not applicable; primarily used for pressure measurement and system servicing.

Material: Brass or stainless steel bodies with rubber or nylon hoses; gauges often feature ABS or polycarbonate cases.

Pressure Range: Low-side (0-250 psi) and high-side (0-500 psi or higher) gauges.

Temperature Range: Typically -30°F to 250°F (-34°C to 121°C).

Compatibility: Works with common refrigerants and oils used in marine refrigeration systems.

Durability: Corrosion-resistant materials for marine environments.

Accuracy: ±2% to ±3% of full scale for most gauges.
