Glyd Ring®

Long Service Life in Reciprocating Cylinder Applications

Glyd Ring Seals

Key Benefits:

  • Used as a rod and piston seal in reciprocating and rotary applications
  • Easy to install
  • Simple groove design
  • One piece construction possible
  • Resistant against shock loads
  • Wear resistant materials ensure long service life
Typical Healthcare & Medical Applications:

Glyd Ring® seals are generally used in reciprocating cylinder applications due to their high side load and shock resistant capabilities. Typical applications are hospital beds and patient lifts.

Materials Specific to Healthcare & Medical

Our Turcon® PTFE based compounds are typically used as the jacket material for most applications. High modulus Zurcon® materials such as UHMWPE or polyester can be used if a more extrusion resistant compound is needed. Many of these compounds are compliant with FDA CFR177.2600, 3-A, USP Class VI, Cytotoxicity (USP 87), NSF, KTW, WRAS etc. NBR, FKM and EPDM are typically used for the O-Ring energizer.

About Glyd Ring®

Glyd Ring® are recommended for applications requiring long service life where the part is exposed to high pressures and side loads. The seals are comprised of two components: a plastic sealing element and an elastomer energizer. Radial notches are machined into the seal jacket to allow the media to quickly fill the groove, loading the elastomer energizer. The design allows the seal to react quickly to sudden changes in pressure or direction, allowing the seal to provide low friction operation with no stick-slip.
