Meter Seals & Bolt Seals: Small Parts, Serious Security
ET Engineering Team 5 min read · September 1, 2026
A security seal is a promise you can see: if it's intact, nobody has been inside. Utilities seal meter terminals; logistics seal containers; customs seal trucks. The chart above shows the two seals we ship by the million — here's where each one earns its keep.
The 2 on the Chart
Wire meter seal (twist-tite, plastic body, cable wire)
The classic utility seal: a one-way plastic body that locks a stainless wire loop through the meter's terminal cover. Once tightened, it only comes off with cutters — and a cut seal is an instant red flag. Custom logos and sequential numbering make every seal traceable to a route or technician.
High security bolt seal (PM-BS9201)
A hardened steel bolt and cylinder that snaps together once and breaks apart only with bolt cutters. The standard for containers, tankers and trailer doors in transit — the seal insurers and customs authorities expect on high-value cargo.
Which Seal for Which Job?
| Application | Seal |
|---|---|
| Electricity / water / gas meter terminals | Wire meter seal |
| Taxi meters, vending, fire equipment | Wire meter seal |
| Shipping containers, truck and trailer doors | Bolt seal |
| Utility cabinets and test benches | Wire meter seal (numbered) |
Ordering Tips
- Put your logo and sequential numbers on the seal — unmarked seals are easy to swap; yours shouldn't be.
- Choose colours per route or region for instant visual control.
- For cargo, specify high-security bolt seals and keep the numbering log with the shipment documents.
Factory-Direct, by the Million
We mould, print and number in-house, so custom-logo seals cost barely more than plain ones at volume. Browse the security seals range, read the manufacturer sourcing guide, or request a quotation with your logo and quantities.
FAQ
Can seals be reused?
No — both types are single-use by design. Any attempt to open them leaves obvious damage.
What's the MOQ for custom logo seals?
Custom printing has a modest MOQ that scales down the per-unit price fast — send your artwork and target quantity.
Do bolt seals meet international standards?
Our high-security bolt seals are produced for ISO 17712-type applications — confirm the exact standard you need with the order.
Conclusion
Wire seals for meters and cabinets, bolt seals for cargo — both with your logo and numbering, both factory-direct. Get your seal quote today.
