The Yellow Jacket 49283 4-Valve TITAN Certified Test/Charging Manifold features a forged aluminum alloy body which makes this unit lightweight for handling ease with the durability and reliability required for repeated use. The front access capability allows for easy field recalibration while the double O-ring piston design provides reliability and a longer service life. The heavy-duty hook extruding from the manifold body is sturdy and will not pull out. The contoured easy-grip handles allow for positive control and are color-coded for ready identification.

The gauges are large and easy-to-read with an 1% accuracy. The sight glass on the gauges allows the user to easily view refrigerant movement and condition during charging and recovery operation. The fourth hose connection enables connection to hi/lo sides, refrigerant tanks, recovery units, or vacuum pumps for diagnostics. Evacuation and charging is possible without switching hoses. The 3/8 inch vacuum port is for use with larger hoses in order to cut evacuation time by up to 33 percent.
