Turcon®Captive Glyd Ring®

• Same functionality as Turcon® Glyd Ring® for linear, helical and rotary service
• Protected from diameter variations of counterpart
• Passes over holes in mating surface
• Increased sealing effect and reduced friction due to narrow contact area
• Simple installation and easy mounting in split groove
• Suitable for narrow grooves
• Design flexibility – adaptable for almost all groove sizes

The Turcon® Captive Glyd Ring® is the best option in applications in which the seal has to slide across mating surfaces that have dimensional changes (e.g. go from a small diameter with sealing function over the seal to a large diameter with no sealing function or vice versa).

Normally, Turcon® Glyd Ring® is usually recommended as a bidirectional seal for all types of pistons and grooves.

However in some applications, in which the Glyd Ring® has to slide across mating surfaces that have dimensional changes, the seal can potentially be deformed, damaged or destroyed, as they may be pressed out of the groove by the O-Ring or the system pressure.

This Turcon® Captive Glyd Ring® version, shown this drawing, is retained in a split groove. The groove prevents the sealing surface from getting damaged by a counter part with variable diameter or when passing holes.
