Customized O Ring
This is a special O Ring product range which L&J work for OEM or customized requirements.
Basically, the demand of customized O Ring is from the following directions:
1. Require very big or long size O Ring.
2. Require very small size O Ring, for example, like 4*0.3mm O Ring only (L&J once made with very good quality).
3. Require special compound property O Ring, for example, we once made O Ring for a chemical factory used on equipment to fit aqua regia which is a very strong acid working environment.
If you have special requirements which is similar with above, please try to make contact with us.
