Review on 🚰 Mityvac MVA6005 16 oz. Fluid Reservoir Kit" -> "Mityvac MVA6005 16 oz. Fluid Reservoir Kit for Enhanced SEO by Simon Nugroho

Listen to the reviews. The cap doesn't seal properly from the bag: it leaks and can't maintain a good vacuum to bleed the brakes. You will need to find your own gasket/o-ring/gasket. I don't know why they sell it incomplete. Use EPDM or PTFE seals with DOT brake fluids as brake fluid is not compatible with common rubber seal materials such as Buna-N (Nitrile) and Viton/FKE. The seal groove measures 45mm ID x 49mm OD. However, it is quite difficult to find a CS O-ring with an inner diameter of 45mm and a size of 2mm. Look for a 45mm ID x 1.5mm CS (metric) ring instead; AS568-031 (1-3/4" x 1/16") can also be used but be careful not to choose PTFE/Teflon as the material as it is smaller and will not stretch. To update. More than 3 times the capacity of the bottle that comes with the hand vacuum pump kit.
