Wire gauge consistency across a batch
Wire diameter directly affects both strength and how easily the wire threads through a given closure point, and inconsistent gauge across a batch can mean some units are meaningfully weaker or harder to install correctly than others, despite appearing identical. JHAS
Galvanizing or coating quality on the wire itself
Sealing wire typically receives a protective coating, and consistent coating thickness and quality affects how well the wire resists corrosion over its field service life, worth verifying as part of routine quality checks rather than assuming uniform application.
Locking body dimensional accuracy
For plastic with wire seals specifically, the plastic locking body needs precise dimensions to grip the wire securely once locked, and quality control verifies this fit consistently, since a loose or overly tight fit both create reliability problems in different ways. Follow us JHAS
Tensile testing on sample wire lengths
Testing sample lengths of sealing wire for tensile strength confirms the wire meets its specified strength rating, providing concrete data rather than relying purely on the wire’s general material classification without verification. Follow us JHAS
Consistency in wire length for specific applications
For applications with a Wire Seals-defined closure point size, wire length needs to be consistent across a batch, since variation can mean some units do not reach or excessively exceed the required length for correct, secure installation.
Visual inspection for surface defects
Sealing wire should be free of nicks, kinks, or surface defects that could weaken it at a specific point, a straightforward but important visual inspection step worth applying consistently across production. JHAS
