Fluoro Carbon Seals

Proper storage practices must be observed to prevent deformation and deterioration of seals. Most synthetic rubbers are not damaged by storage under ideal conditions. However, most synthetic rubbers will deteriorate when exposed to heat, light, oil, grease, fuels, solvents, thinners, moisture, strong drafts, or ozone (form of oxygen formed from an electrical discharge).

Damage by exposure is magnified rubber is under tension, compression, or stress.

There are several conditions to be avoided, which include the following:

• Deformation as a result of improper stacking of parts and storage containers.


• Creasing caused by force applied to corners and edges, and by squeezing between boxes and storage containers.


• Compression and flattening, as a result of storage under heavy parts.


• Punctures caused by staples used to attach identification.


• Deformation and contamination due to hanging the seals from nails or pegs. Seals should be kept in their original envelopes, which provide preservation, protection, identification, and cure date.


• Contamination by piercing the sealed envelope to store O-rings on rods, nails, or wire hanging devices.


• Contamination by fluids leaking from parts stored above and adjacent to the seal surfaces.


• Contamination caused by adhesive tapes applied to seal surfaces. A torn seal package should be secured with a pressure-sensitive moisture proof tape, but the tape must not contact the seal surfaces.


• Retention of overage parts as a result of improper storage arrangement or illegible
  identification. Seals should be arranged so the older seals are used first.
