Refrigerant Charging Hoses and Couplings for HVAC-R Systems
Refrigerant hoses and couplings are essential tools for diagnosing, repairing, and maintaining HVAC and refrigeration systems. Designed to withstand high-pressure applications, these components offer safety, durability, and leak-free performance - critical when working with modern refrigerants.
High-Pressure Charging Hoses Our selection of charging hoses is built to handle pressure bursts up to 4,000 PSI, ensuring safe and efficient refrigerant transfer. We offer hoses in multiple connection sizes - 1/4", 3/8", and 5/16" - to suit various system requirements. Colour-coded options are available in Red, Blue, and Yellow, as well as solid Black and Yellow, depending on the model.
Mastercool hoses are constructed using Grade 5 materials, nylon barriers, and knurled brass nuts, delivering long-lasting performance and secure connections.

All hoses in our collection are compatible with CFC, HFC, and HCFC refrigerants, making them versatile for both residential and commercial HVAC systems.
