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.

O-Rings are a critical component for the proper sealing of specific pipes. They have to sit within a specified groove, which can vary based

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%.

O-Ring Gland Fill %O-Ring Volume) / (Gland Volume) Gland volume vs. O-Ring volume. About 25% void space or 75% nominal fill. Need space in groove to allow for volume swell, thermal expansion, and increasing width due to squeeze. Narrower groove for sealing vacuum or gas. O-Ring can extrude into clearance gap or get squeezed in two directions.
