The Mastercool 85772-M 2-Valve Metric Aluminum Manifold is constructed out of the finest materials and machined with precision in order to create a durable manifold set. The solid extruded aluminum body and free-floating piston type valves which reduce O-ring wear both allow for a higher level of durability and a longer service life. The knobs on the manifold are large and easy-to-grip while the body includes an extra access port for a vacuum line.

The gauges are silicone-dampened in order to smooth out needle movement and provide the user with more accurate measurements. The gauges can be easily recalibrated in the field in order to maintain accuracy. The extra-large sight glass on the gauges allows for an easy visual refrigerant check during operation.
