TY-274 Silicone Diffusion Pump Oil

Chemical name: 1,1,5,5-Tetraphenyl-1,3,5-tetramethylsiloxane

CAS No: 3982-82-9

Description:

It is a colorless transparent oily, single-component fluid designed for high vacuum of 10-7torr (untrapped). It performs well in tough, rugged applications and offers quick pump down, even after exposure to air at operating temperatures. TY-274 is thermally and chemically stable allowing it to keep pump jets free of tars and hard carbon.
