The MASTERLOCK 51261 is a 2-way aluminum manifold gauge set designed for refrigerant service work on systems charged with R410A or R32. The manifold features 3/8-inch ball valves for precise refrigerant flow control and ships complete with three 60-inch hoses, giving technicians reach to service equipment without repositioning the manifold. The aluminum body keeps the set lightweight while providing durability under field conditions. The complete set arrives in a plastic storage box for organized transport and storage between jobs.
This manifold set is suited for residential and light commercial HVAC service applications where R410A or R32 refrigerants are used. It is appropriate for charging, evacuating, and pressure testing refrigerant circuits. Licensed HVAC technicians and refrigeration mechanics performing routine seasonal service, leak verification, or refrigerant recovery tasks will find the included hose length and ball-valve design practical for standard split system and packaged unit service calls.
Designed for use with R410A and R32 refrigerant systems. Verify hose fitting compatibility with the service ports on the specific equipment being serviced before use.
Installation and use should be performed by EPA Section 608 certified HVAC technicians familiar with refrigerant handling requirements. Always recover refrigerant in accordance with applicable regulations before opening any refrigerant circuit. Inspect hose fittings and manifold connections for leaks before beginning service, and confirm refrigerant compatibility before attaching the manifold to any system.
