Manifold, Four Valve Aluminum R-410A/R-22/R-404A/R-134A

The Uniweld Aluminum Manifold with 3-1/8″ NPF® Gauges is a high-performance HVAC tool engineered for efficient charging, evacuation, and testing of air-conditioning and refrigeration systems. Built with an anodized aircraft-grade aluminum block body, it offers excellent durability while remaining lightweight for easy handling.

Featuring a 4-port design, this manifold allows technicians to perform multiple operations without changing or removing hoses, saving time and improving workflow efficiency. The inclusion of a 3/8″ SAE port significantly enhances vacuum capacity, enabling faster evacuation of systems.

The manifold is equipped with large 3-1/8″ NPF® (No Pointer Flutter) gauges, ensuring stable, accurate readings with color-coded refrigerant scales and protective boots for easy identification. An optical sight glass is also integrated for clear monitoring of refrigerant flow during operation.

Designed for precision and comfort, it includes durable brazed brass T-handles that provide smooth and accurate control. The unit comes with a complete 5 ft. hose set, including Soft Magic® barrier hoses with EZ-Turn anti-blowback fittings, ensuring safe and efficient refrigerant handling.
