o-ring design guide

As important as the o'ring seal itself is the groove that the o'ring seats into. The groove must be designed to accommodate not just the o'ring size, but also 

12. O-ring Gland Design The following pages contain basic O-ring gland design information. Please contact the local ERIKS repre-sentative if an application does not clearly fall into these design parameters. Static Applications There are five types of static O-ring applications: • Flange seal • Radial seal • Dovetail seal • Boss seal

The Apple Rubber Seal Design Guide was first published in. 1989 and fast became more popular and concepts of O-ring design, seal types and gland.

For the extrusion gaps, SKF recommends machining the fits according to the following tolerance classes: F8and H9 for diameters up to 120 mm. F7and H8 for diameters larger than 120 mm. Diagrams 1 to 3 provide guideline values for the maximum extrusion gap in relation to the operating pressure for standard O-rings without back-up ring ( diagram 1

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, 

One general guideline to consider when designing a seal is to maintain a range of % squeeze on the o-ring (~10-40% for static and no more than 30% for dynamic). No less than 75% of the seal cross-section should be contained within the groove

O-ring Gland Design If friction is excessive a variety of possible solutions exist: • Select a different O-ring hardness. • Select a different O-ring material with improved coefficient of friction. • Increase the groove depth. • Consider the use of an alternate design of seal. • Viton®has much lower friction than NBR or EPDM or Silicone.

The O-Ring Example Throughout this guide, the o-ring is used as an example in our discussion of seal design principles. We have made this choice for these reasons: It is the most common and most widely known type of seal in use today. It is used in all types of applications and by a broad range of industries.

O-Ring Groove (Gland) Design Guide. For rotary O-rings: a compression ratio of 0-10%. For reciprocating O-rings: a compression ratio of 10-20%. For a static male to mating interface: a compression ratio of 18-25%. For a face seal: a compression ratio of 20-30%.

HITECHSEALS.COM7 O-Ring Design Guide O-Ring Selection Machining Specifications The gland fill is the percentage of the gland that is occupied by the O-ring. It is calculated by dividing the cross-sectional area (CSA) of the O-ring by the cross-sectional area of the gland. Gland CSA = D x w* * Effect of gland angle and extrusion gap not addressed.
