The Mastercool 87772-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 allows for a higher level of durability and a longer service life. The knobs on the manifold are large and easy-to-grip. The stainless steel ball valve design controls flow smoothly and quickly with only a quarter turn.

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.
