The BSC PREFERRED SE1040S is a tamper-evident security seal made from tin plated steel, sold in cases of 200. Once applied, removal is impossible without leaving clear physical evidence of tampering, making these seals well-suited for securing equipment access panels, valve handles, meter covers, and other components that require documented integrity. Each seal applies without the use of tools and is embossed with sequential numbering and the word Secured for easy tracking and chain-of-custody documentation. This type of seal is commonly used by HVAC technicians, plumbers, electricians, and utility service professionals who need a low-cost, reliable method to indicate whether a secured component has been accessed.
These seals are appropriate for both residential and light commercial service environments. Typical applications include sealing refrigerant access ports, electrical panel knockouts, gas meter connections, and other service points where tamper indication is required by code, contract, or manufacturer warranty terms. The sequential numbering allows technicians to log seal numbers on service records, supporting audit trails and compliance documentation. The tool-free application makes them practical for field use where speed and simplicity are priorities.
The SE1040S is equivalent to part number H-541. Designed as a general-purpose tamper-evident security seal for use across HVAC, plumbing, electrical, and utility service applications where tool-free, single-use sealing is required.
Application requires no tools - thread or loop the seal through the target anchor point and engage the locking mechanism by hand. Ensure the sealing surface is clean and dry before application to achieve a secure set. Log the embossed sequential number on the corresponding service record before leaving the job site. Seals are single-use only and must be replaced, not reused, after any legitimate access to the secured component.
