Hoses and Couplings

Refrigerant hoses and couplings are fundamental tools for HVAC and refrigeration diagnosis, repair, and maintenance. Charging hoses are built to prevent leakage when using high-pressure refrigerants and can handle pressure bursts from 3000 to 4000 PSI for maximum safety. Cooltools HVAC-R has a varied inventory of high-quality charging hoses and couplings from the best brands like Mastercool, Imperial, Javac, and Robinair.

We carry charging hoses in most connection sizes from 1/4”, 3/8” and 5/16“ and in various colours, including Red, Blue, Yellow, solid Black, or solid Yellow, depending on the model and type of hose. Mastercool charging hoses utilize Grade 5 materials, nylon barriers, and knurled brass nuts to offer outstanding reliability and durability. Simultaneously, Robinair has a selection of high-quality charging hoses with knurled coupler nuts and standard straight fittings. All Imperial Tools PolarShield® charging hoses are UL recognized and are compatible with all CFC, HFC & HCFC refrigerants. 

We also carry automotive couplers from Javac, Mastercool, and Imperial to effectively diagnose or recharge your vehicle’s faulty HVAC system. The knobs are colour-coded for high and low connections.
