V2B Vent/Vacuum Breaker Gaskets - Retainer Ring
Rubber Fab V2B Vent Vacuum Breaker Retainer Rings are constructed from heat traceable 316L Stainless Steel for use in your sanitary systems. These retainer rings hold your V2B gaskets securely on the ferrule to ensure no particles bypass the mesh screen. All V2B Vent Breaker Gaskets require the use of a retainer ring.
Rubber Fab's V2B Vent and Vacuum Breaker system is a cost effective and incredibly simple way to provide contaminate free air flow to any tank system. The V2B Gasket is the answer for vacuum and pressure relief in pharmaceutical and food/beverage processing tank applications where airborne particulate removal is required. Using a 200 mesh screen combined with a 14 mesh screen of sintered construction, Rubber Fab has created a cost effective alternative to expensive vacuum breakers and venting systems. Because the V2B Gasket can provide unrestricted air flow with ultra fine filtration, you can feel secure in knowing the hygienic condition of the tank contents remain protected. With regular cleaning and maintenance, the V2B Gasket is a cost effective and incredibly simple way to provide contaminate free air flow to any tank system.
The V2B System is attached using a standard Sanitary Tri-Clamp® to a sanitary tank port, just like traditional vacuum breakers. You can run the V2B Vent Vacuum Breakers in vertical, horizontal, single, or multiport configurations without any special fabrication or expensive tooling. You can even increase the airflow of your system by using a Clamp x Clamp Concentric Reducer to run a larger V2B gasket than your tank was designed for. The V2B Screen will fit perfectly into the ID of sanitary tubing and can be used for inflow fluid conditioning filtration as well.
