Where an all-plastic locking point can fall short
The locking point on any seal is the single most stressed part of the mechanism, the spot where an attempt to defeat the seal concentrates the most force. On a purely polycarbonate meter seal design, this point is only as strong as the molded plastic itself, which, however well engineered, has real limits under sustained or forceful tampering attempts.

What the steel plunger changes
PLASTEEL replaces the plastic locking point with a stainless steel plunger, giving the single most vulnerable part of the seal a metal-grade resistance to force while keeping the rest of the seal body in lightweight, cost-effective Polycarbonate Meter Seals Meter Seals. This hybrid approach targets reinforcement specifically where it matters most rather than switching the entire seal to metal construction.

Why this matters for higher-risk installations
For meters or containers in locations with a documented history of tampering attempts, or applications where the consequences of a breach are more severe, PLASTEEL offers a middle ground between standard Polycarbonate Meter Seals seals and full metal cable seals, with stronger resistance at the critical locking point without the added weight, cost, and handling complexity of an all-metal seal.

Corrosion resistance from the stainless steel choice
Using stainless steel specifically, rather than standard steel, for the plunger component matters for outdoor installations exposed to moisture and weather. A plunger that corrodes over time can weaken or seize, undermining the exact reinforcement the design is meant to provide, so the stainless steel specification is a deliberate durability choice, not an arbitrary material selection.

Applications suited to this configuration
PLASTEEL seals fit well on energy meters in higher-risk zones, drums and containers carrying valuable contents, and any application where a standard polycarbonate seal has previously shown signs of forced tampering, indicating a need for a stronger locking point specifically.
Weighing PLASTEEL against other high-security options
PLASTEEL sits between standard Polycarbonate Meter Seals and full metal cable or bolt seals in terms of both cost and security level, making it a practical choice when full metal construction is not necessary but standard polycarbonate has proven insufficient for a specific application’s risk profile.
