Designed for fluid systems where cleanliness is paramount and entrapment areas must be minimized, the TS series biopharm fittings virtually eliminate fluid holdup at connection points. The fittings maintain a boreline seal, coupled with a metal-to-metal stop to improve drainage and cleanliness.
The design of the fittings resolves problems faced when using conventional ISO 2852-style sanitary fittings: gasket extrusion, both during make-up and at elevated temperatures, and the resulting fluid holdup. A metal-to-metal stop controls gasket compression and prevents overtightening while minimizing ferrule movement. The design’s crown holds the gasket in place and directs expansion to space provided, while a gasket rib creates the boreline seal. The expansion space allows for gasket expansion during thermal cycling, and minimizes gasket intrusion into the boreline. Seals remain leak-tight throughout pressure-temperature rating range.
TS series fittings are available with a 316L stainless steel ferrule and a choice of three gasket materials; PTFE, EPDM, and Fluorocarbon FKM. The gaskets are compliant with Food and Drug Administration specifications. The complete line of fittings includes ½-, ¾-, 1-, 1 ½-, 2-, 2 ½-, 3- and 4-in. sizes.
