Uniweld a2lm5ez Manifold Set R-32 R-454B R-448A R-410A

Product Description

The UNIWELD a2lm5ez is a refrigerant manifold set designed for HVAC technicians working with A2L and legacy refrigerants. It reads pressure in Fahrenheit and PSI and ships with 5-foot EZ Turn hoses that reduce kinking and allow smooth valve actuation during system service. Compatible refrigerants include R-32, R-454B, R-448A, and R-410A, making this manifold a practical tool for technicians transitioning from legacy systems to lower-GWP A2L refrigerants. The set weighs 3.5 pounds and is built for field use across residential and light commercial HVAC applications.

This manifold set is suited for residential and light commercial split systems, heat pumps, and package units that use R-410A or the newer A2L refrigerants R-32, R-454B, and R-448A. It is a relevant tool for technicians currently servicing R-410A equipment and preparing for systems charged with next-generation low-GWP refrigerants. The EZ Turn hose connections reduce hand fatigue during repetitive hookups on rooftop or indoor air handler service calls.

• 5-foot EZ Turn hoses included for easier connection and reduced kinking
• Supports A2L refrigerant service for technicians transitioning from R-410A systems
• Compact field-ready design at 3.5 pounds

Compatibility

Designed for use with systems charged with R-32, R-454B, R-448A, or R-410A refrigerants in residential and light commercial HVAC applications.

Installation Notes

Installation and use should be performed by EPA Section 608 certified HVAC technicians. When working with A2L mildly flammable refrigerants such as R-32 and R-454B, follow all applicable safety protocols for flammable refrigerant handling, including ensuring no ignition sources are present in the work area. Always recover refrigerant before disconnecting hoses and verify system pressure is within gauge range before connecting. Refer to equipment manufacturer service instructions and local codes for proper procedures.
