WebbThis is necessary to ensure room for the O-ring’s thermal expansion (elastomers expand around 10 times more than metals), swelling due to soaking up fluids, and increasing width due to O-ring squeeze. The optimal ratio for O-ring gland volume is 15-25% empty space and 75-85% spaced filled by the O-ring material. WebbO-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 ...

WebbIn most rotational shaft applications, o-ring squeeze should be kept to as little as 0.002" by using an o-ring with an O.D. of about 5% larger than the accompanying gland. Once installed, peripheral compression puts the o-ring's I.D. in light contact with the turning shaft. This design minimizes frictional heat buildup and prolongs seal life. WebbMost O-ring seal applications cannot tolerate the no squeeze condition, the exceptions are the floating ring designs in special pneumatic and rotary applications. The most …
