Metal tubes can have grooves or surface scratches in their length direction during production.
Because of this perfect searling effect can not be obtained, so LOCK SEAL can be applied to the end of the tube to achieve perfect sealing effect. Rather than being an adhesive, LOCK SEAL is in fact an anaerobic sealant that hardens under oxygen exclusion and when in contact with free metal ions. It providK the effect of filling grooves or scratches on the surface of the tube, reinforcing and searling the tube connection, but it is not an adhesive to the surface of the tue, so it is necessary to regularly manage the tube dimensions and tools.
