The Mastercool 83472-MG 2-Valve Metric Brass Manifold is constructed out of the finest materials and machined with precision in order to create a durable manifold set. The heavy-duty forged brass 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 large, all-metal handles are angled for ease of operation. The hose holder provides the user with convenient storage for the refrigerant hoses.

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. Shock-resistant gauge protectors work to protect the gauges from surge or shock waves while the manifold is in operation.
