Daemar Inc. PTFE Encapsulated O-Rings 457-TEV

PTFE Encapsulated Viton® o-rings are o-rings consisting of a seamless and uniform PTFE FEP/PFA encapsulation/jacket which completely encloses a core material Viton® fluoroelastomer (also available in silicone/buna/epdm). The combination of these components creates an o-ring that is virtually chemically inert and compression set resistant for use in harsh sealing environments. Encapsulated o-rings will decrease downtime and hence increase profitability wherever corrosive fluids and gases cause premature seal failure. DMR™ encapsulated o-rings match the chemical and temperature resistance of solid PTFE o-rings, in addition PTFE encapsulated o-rings possess properties of elasticity and recovery which are crucial in many sealing applications. DMR™ encapsulated o-rings withstand breakdown caused by industrial solvents and corrosive materials at elevated temperatures from -60 ºC/-75 ºF to +205 ºC/400 ºF (See General Specifications). DMR™ encapsulated o-rings can economically and effectively replace other expensive and exotic o-ring compounds.
