In part one of our seal failure blog series, we will discuss the compression set, extrusion, and spiral failure. Compression set Compression set is likely the most common failure mode for elastomer seals. Compression can be defined, or rather quantified, by the seals' ability to return to its original shape after compression is removed.

Some conditions which cause an O-ring to slide and roll at the same time may be: 1. Eccentric components. 2. Wide clearance combined with side loads. 3. Uneven surface fi nishes. 4. Inadequate or improper lubrication. 5. O-ring too soft. 6. Stroke speed (usually too slow). 7. Improper installation (O-ring pinched or rolled). 8.

Static O-Ring Sealing Failure Modes Mobile inPHorm - Parker's Design Tool & O-Ring Calculator Fluorocarbon (FKM) Fluorocarbon (FKM) has excellent resistance to high temperatures, ozone, oxygen, mineral oil, synthetic hydraulic fluids, fuels, aromatics and many organic solvents and chemicals.
Compression Set & Spiralling Compression set is the most common failure mode found in O-Ring seals. Compression set, or stress relaxation, results in a loss of sealing pressure (or squeeze) on the hardware allowing the …
Solutions to Ozone degradation are: 1. Select a material with ozone resistance, such as HNBR, FKM, etc. 2. Do not store the O-ring in a stretched condition while exposed to air or ozone. 3. Coat the O-rings with a silicone or petroleum lubricant Prevention / Correction for Chemical Attack 1.
Failure Modes Compression Set Compression Set is when the O-ring ceases to be "O" shaped and is permanently deformed into a flat sided... Extrusion and Nibbling A typical example of O-ring extrusion is when edges of the ring on the low pressure or …

NBR is not resistant to weathering and ozone. Temperature Range: -65°F to 250°F (-53°C to 121°C) Certifications include Mil-P-25732 Chemical resistance
Probably the best way to prevent damage to O-rings during installation is the use of good old-fashioned "Common Sense." There are some specific solutions which are listed below: 1. Break all sharp edges on metal components. 2. Provide a 20° lead-in chamfer. 3. Check all components for cleanliness before installation. 4.
