Mastercool R1234YF Aluminum Manifold Gage Set

Ensure accuracy and efficiency in your automotive A/C system with this high-quality manifold gage set. The anti-flutter gauges smooth out needle movement, while the E-Z to read temperature scales on gauge face make it easy to monitor refrigerant levels. The extra large sight glass allows for visual checks of refrigerant, and the easy grip front-facing knobs make adjustments a breeze. The piston type free-floating valves reduce o-ring wear, and the manifold block is assembled with (3) 12mm-F fittings per SAE J2888. The set includes red and blue nylon barrier hoses with 12mm-M fittings on both sides, meeting SAE J2888, EPA, SAE, and UL standards. The yellow hose features a 12mm fitting on one side and 1/2 x 16 acme on the other, meeting SAE J2888. The R1234yf high and low side couplers with extended disconnect protection sleeve meet SAE J639 and J2888.
