<p><strong>Introducing the world's most advanced venturi mixers that are virtually maintenance free, highly accurate, and provide easy and fast adjustment. Groz mixers use a rotary disc valve which is precision CNC machined from stainless steel. Other venturi coolant mixers are designed with either a needle valve or set of mixing jets. These designs can be time consuming to adjust, have too many parts, and/or are prone to blockage. The Groz Plus Antifreeze/Detergent Mixer's rotary disc valve is highly accurate, and their compact construction and minimal parts make these coolant mixers easy to install and highly reliable.</strong></p> <p>NOTES:</p> <ul> <li>Groz has made specific modifications on these mixers for Coolant Consultants, lengthening and switching the suction pipe from plastic to threaded stainless steel</li> <li>Mixing percentage achieved can be dependent on incoming water pressure</li> <li>3/4" female garden hose brass swivel adapter included</li> </ul>
