SGT & SST – AGGRESSIVE CHEMICAL SERVICE
The unique, chemically inert quality of Teflon* makes Peraflex SGT & SST hoses ideal for aggressive chemical transfer when a polypropylene liner is inadequate. SGT & SST hoses are constructed around a Teflon* (PTFE / FEP) liner that is reinforced with additional layers of films and seamless tubes offering exceptional leak prevention safety and reliability.
Typical Conveyance
Butyl chloride, phosphoric acid, chlorosulphonic acid, oleum and ketones.
**Refer to chemical compatibility chart for specific recommendations**
