PTFE Shaft Guide, HP (With NPT Threads)

HP Shaft Guides provide an effective guide for use with glass and metal Shaft Stirrers over a wide range of temperature without shedding particles from the seal whilst maintaining vacuum.



The seal is made from a specially formulated PTFE-PEEK composite and this material is also used to provide a molded-in guide ring to aid alignment of the shaft.

Note: PEEK has reduced chemical resistance compared to PTFE and may be affected by acids, phenols and halogen based compounds.



Maximum recommended speeds: continuous 500rpm; intermittent 800rpm



HP Shaft Guides have an NPT thread for direct assembly into Cowie PTFE Reactor Lids.
