Rubber Fab V2B Vent Gasket Retaining Ring - Stainless Steel - 2 1 /2" - Silver

V2B Vent Gaskets

Rubber Fab V2B Vent Gaskets are sanitary vent gaskets designed for use in food, dairy, beverage, biotech, and pharmaceutical processing systems where venting at the clamp connection is required. The V2B design allows gases to escape from the pipeline at the gasket connection point during sterilization, CIP, or other process cycles, preventing pressure buildup that could compromise the integrity of the seal or the surrounding equipment. ADI Free (Animal Derived Ingredient Free); these gaskets meet the hygienic standards expected in regulated sanitary process environments.

We offer the stainless steel V2B retaining rings, which secure the vent gasket in place within the Tri-Clamp® connection for a stable, reliable installation. Available in nominal diameters from 1-1/2" through 4", the retaining rings are a required companion component for proper V2B vent gasket assembly and are sold individually for easy replacement as part of a routine maintenance program.

V2B Gasket: The Vent and Vacuum Breaker Gasket

The V2B System is attached/connected using a standard sanitary Tri-Clamp® to a sanitary tank port, the same way a standard vacuum breaker in installed. Installation can be horizontal, vertical or in single or multiple port configurations (i.e. manifolds) without special fabrication or expensive tooling. The V2B screen will fit perfectly into the ID of a sanitary pipe and can be used for inflow fluid conditioning filtration.

Providing Air Flow Without Contamination

A key benefit of the V2B Gasket is it’s prevention from most atmospheric and environmental contamination customarily found with other 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.

About Rubber Fab Gaskets

Tuf-Flex®: Tuf-Flex® is the world’s first unitized gasket, setting new standards for purity, performance and flexibility. A Tuf-Flex® Gasket’s contact surface is PTFE unitized to an EPDM rubber inner core. This totally bonded construction provides a PTFE gasket with the mechanical characteristics, including memory, of an elastomer gasket. Designed to meet critical requirements in biopharmaceutical, ultra-pure water, WFI (water for injection) and difficult food and beverage processing.

Tuf-Steel®: Tuf-Steel® is composed of a unique 50/50 blend of non- pigmented PTFE and 316L passivated and atomized stainless steel. Testing and seven years of documented application usage has demonstrated that Tuf-Steel® is the choice for perfect surface performance, outstanding durability and extended service life in both SIP (steam in place) and WFI (water for injection) applications. Tuf-Steel® is ideal for sanitary steam pipe connections in extreme temperatures ranging from -320°F to 550°F. The superior strength of Tuf-Steel® eliminates creep and cold flow providing a leak-free seal and preventing maintenance problems and system downtime.

PTFE: PTFE is the material of choice whenever low temperature flexibility or gasket memory is not required and can remain in service for longer periods of time in both water andsteam applications. PTFE is not recommended with large temperature variations due to creep and cold flow. PTFE has minimal extractables, has a low absorption rate and excellent resistance to process fluids.

Platinum Cured Silicone: Platinum Cured Silicone is the material of choice in sanitary water systems when PTFE is not feasible due to severely misaligned fittings, or if the cost of high pressure clamps does not outweigh the benefits of PTFE (extended service life). See Rubber Fab’s Platinum Silicone Hygienic Seal literature for more information.

FKM & EPDM: FKM Fluoroelastomer and EPDM compounds are specified by many of our process equipment manufacturers. They are generally suitable for these applications, however, service life must be considered and a preventative maintenance program be implemented to mitigate degradation.

Buna: Buna is the last choice in most applications due to temperature limitations and does not pass U.S. Pharmacopeia Class VI Certification and Cytotoxicity.
