Quick Release Fittings (QRF) for DI, DII, D3

The Quick Release Fittings (QRFs) are the two white plastic pieces that attach the tubing to the machine. They were designed to take the brunt of the abrasive crystals going through the machine. They keep the machine from wearing out but they will wear out approximately every 50 machine hours and need replacing. When they start to wear out it will cause an air hole in the vacuum system, so there will be disruption in the vacuum, causing either low suction and/or lots of crystal flow.
