V2B Vent/Vacuum Breaker Gaskets - EPDM (14/200 Mesh Screen)
Note: These gaskets require the use of the V2B Retainer Ring (sold separately)
Rubber Fab EPDM V2B Vent Vacuum Breaker gaskets are a good choice when an economical solution for weather and chemical resistant seals is desired. Chemically, EPDM has good resistance to animal oils, vegetable oils, ozone, strong chemicals, and oxidizing chemicals. Do not use EPDM gaskets for mineral oils, solvents, or aromatic hydrocarbons.
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.
