Torque Rite (Tux-Flex & Tuf-Steel)

Torque-Rite® allows you to control compression and expansion while maintaining constant inch/pounds force insuring a Perfect Surface I.D. when used with a Perfect Surface Gasket. Torque-Rite® eliminates the problems associated with over - or under-tightening a gasket which can lead to an unsanitary system. 
Patent #6,082,941

Torque-Rite allows you to control compression and expansion while maintaining constant inch/pounds force insuring a Perfect Surface I.D. when used with a

Perfect Surface Hygienic Seal - Torque-Rite eliminates the problems associated with over - or under-tightening a seal which can lead to an unsanitary system.

Compression control is easy!
When tightened, the Torque-Rite’s self limiting internal mechanism will make an audible “click” signaling the user they have reached proper inch/pounds force. If further tightening is attempted, there will be more “clicks” but no additional application of force on the hygienic seal (if emergency conditions arise, the Torque-Rite has a built-in manual override feature).

Problems with over-tightening or under-tightening a hygienic seal:
Over-tightening can tear or damage a seal and can also cause a damming effect inside the pipeline. A torn or extruded seal can hold soil and bacteria. Under-tightening leaves an undesirable concave area at the seal allowing soil and bacteria to become entrapped. Both conditions should be avoided in a sanitary system.

Maintaining a “Perfect Surface” Sanitary System.
By maintaining a constant force on a Perfect Surface Hygienic Seal with the Torque-Rite, seal I.D. is maintained lowering bacteria count and enhancing product integrity.
A Perfect Surface sanitary system is assured.

Torque-Rite® Features:
• An audible “click” indicating correct inch/pounds force
• Maintains constant 30 or 50 inch/pounds force
• Manual override feature
• Retrofits all sanitary clamps, mini through 6"
• Works in rupture disk applications
• Works with all Smart Gasket® products including spore trap, thermo-coupler and sampling injection tube
• No torque wrench or special training required
• User friendly

Tuf-Flex (move to pdf)

Introducing a technologically advanced new hygienic seal, TUF-FLEX®. This revolutionary new seal from Rubber Fab Technologies Group is the world’s only unitized seal, setting new standards for purity, performance and flexibility. Designed to meet critical requirements in pharmaceutical, biotechnology, ultrapure water and WFI (water-for-injection). WFI (water-for-injection) and difficult food and beverage processing, Tuf-Flex outperforms other hygienic seals while eliminating costly process interruptions.

Performance Based on a Revolutionary Composition
A Tuf-Flex hygienic seal’s contact surface is a layer of PTFE grafted to an EPDM rubber inner core. This totally bonded construction provides an exceptionally pure and incredibly flexible seal. By grafting the elastomer with a layer of PTFE, Tuf-Flex will behave like an elastomer but will prevent the product contamination, service interruptions and clean-up costs associated with elastomer seals.

Performance With Exceptional Purity
Because its elastomer core is protected by a unitized layer of PTFE, Tuf-Flex hygienic seals will not release elastomer extractables or particulates totally eliminating spalling. The result is an exceptionally maintained sanitary tubing I.D. with no I.D. invasiveness or system contamination.

Tuf-Steel (move to pdf)

Tuf-Steel easily outperforms standard solid PTFE and PTFE envelope seals under even the most demanding S.I.P. pharmaceutical applications. In fact, Tuf-Steel lasts at least five times longer in most applications!

Prevents System Downtime
The unparalleled strength of Tuf-Steel eliminates maintenance needs and helps prevent system downtime by eliminating cold flow creep. This makes Tuf-Steel ideal for sanitary steam pipe connections in both extreme cold (down to -100°F) and hot conditions (up to 500°F). Tuf-Steel hygienic seals are available in a variety of sanitary standard sizes from 1/2" to 12" diameter to service virtually any S.I.P. application. Plus, Tuf-Steel works with the Torque-Rite™ Perfect Surface Hygienic Seal System. This eliminates the potential for bacterial entrapment problems caused by over-tightening or under-tightening a hygienic seal.

TUF-STEEL®: The S.I.P. Leak Proof Solution
There’s a new standard in S.I.P. (steam in place) hygienic seal stability and longevity. With a unique 50/50 blend of non-pigmented PTFE and 316L water atomized and passivated stainless steel, Tuf-Steel is one tough gasket.
