Elastomeric O-Ring Seals
Elastomeric O-Rings continue to be the most versatile sealing product manufactured today.
The proper amount of 'Squeeze,' or the relationship between the O-ring cross section and the hardware grooves, is best designed in consultation with a Gallagher engineer.
Non-Standard diameters can be extruded and spliced as 'Cord-Rings.' The bond on these seals is of varying strengths so consult a Gallagher engineer.
O-Rings continue to be the most widely utilized sealing product. While the ‘Donut’ shaped profile has by and large been kept intact since their inception, continued elastomeric development has pushed O-ring temperature and chemical compatibility to limits unimaginable several decades ago.
The following advantages of O-rings are as relevant today as they were at their inception. O-Rings seal over a wide range of pressure, temperatures and tolerances. They also have tremendous ease of service over the course of product life and use a small percentage of hardware space. O-Ring failure is typically gradual and easily identified. Finally, they are a cost-effective sealing solution relative to their product counter parts.
