PTFE High Performance (HP) Shaft Guide
HIGH PERFORMANCE (HP) SHAFT GUIDE
WITH NPT THREAD
Cowie® 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 moulded-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.
The maximum recommended speed is 500rpm continuous
HP Shaft Guides have an NPT thread for direct assembly into Cowie® Reactor Lids.
