Hallite New Type 844 Wiper

Seal & Design now offers the Hallite type 844 wiper.  The double lip design of the Hallite Type 844 has a special feature of a flap on the external wiping lip which covers the gland housing. This flap prevents the water/slurry trap occurring which is so common with conventional wipers and thereby stops contamination from getting around the outside of the wiper.

The Hallite wiper showed its ability to clear surface frost/ice whilst operating at temperatures down to -45°c and also working in environments of 110°c radiated heat.  See video below:

New Teflon Encapsulated O-Ring Page

teflon encapsulated o-ringSeal & Design has updated it’s Teflon encapsulated o-ring page, and included a Adobe PDF link giving you the different options for core and jacket materials.  Teflon Encapsulated O-rings combine the qualities of Teflon (PFA/FEP) with Viton® or Silicone rubber. They have an outer jacket of teflon protecting the resilient core from virtually all chemicals.

The rubber core is totally encapsulated by Teflon (PFA/FEP) and this unique combination enables encapsulated o-rings to give maximum protection against leaks in a wide range of sealing applications. Teflon (PFA/FEP) has always been recognized as an ideal, chemically resistant, sealing material but it lacks elasticity. The Viton® or Silicone rubber core provides this missing element of memory, together with exceptionally good resistance to compression set, even at high temperatures.
