How To Store O-rings
Long-term storage of seals can cause physical changes, including hardening, softening, cracking or decomposition.
The factors caused are damage, oxygen, light, ozone, temperature, humidity, oil or solvent.
The following are the conditions for storage of rubber products:
1、The ideal storage temperature of the seal is 5 ° C ~ 25 ° C.
2、The seals should be kept away from direct sunlight and placed in the dark as much as possible.
3、The seal is placed in a confined space to avoid contact with air.
4、The seal should be placed flat without heavy pressure to avoid deformation. Do not hang with hooks, screws, ropes, etc.
5、The storage period of common rubber materials:
