UNIVERSEAL

UNIVERSEAL is a brand of tamper-evident security seals used to indicate whether enclosures, containers, meters, and cabinets have been opened. The product line supplied by 3G Electric includes plastic strap seals and plastic hasp padlock seals, both supplied in 50-piece packs and marked with black sequential numbering and the message 'Sealed'. These are single-use indicating devices: once the seal is broken or cut, the numbered strap or hasp cannot be reclosed without leaving visible evidence. That makes them suitable for inventory control, utility metering, freight, and any process where a record of seal number against asset or shipment is maintained.

About UNIVERSEAL

UNIVERSEAL is a brand of tamper-evident security seals used to indicate whether enclosures, containers, meters, and cabinets have been opened. The product line supplied by 3G Electric includes plastic strap seals and plastic hasp padlock seals, both supplied in 50-piece packs and marked with black sequential numbering and the message 'Sealed'. These are single-use indicating devices: once the seal is broken or cut, the numbered strap or hasp cannot be reclosed without leaving visible evidence. That makes them suitable for inventory control, utility metering, freight, and any process where a record of seal number against asset or shipment is maintained.

The strap seal range uses a 6-inch strap length and 3/8-inch strap width, with a 50 lb breaking strength. The strap is plastic and the marking is laser applied in black, which produces a durable, legible number on each seal. Strap seals are available in multiple colors, including red, green, and yellow, allowing color-coding by route, shift, region, or asset class. The hasp padlock seal range uses a 1-1/4 inch hasp length and a 15 lb breaking strength, with a plastic lock body. Hasp padlock seals are also available in several colors, including blue, red, yellow, green, orange, and black. Both families are packed 50 per pack, and each seal carries a unique sequential number plus the 'Sealed' message.

For technical buyers, the relevant selection criteria are the breaking strength, the dimensions of the strap or hasp, the marking method, and the color. The 50 lb strap seal is intended for applications where a stronger tamper-indicating tie is needed, while the 15 lb hasp padlock seal is a lighter-duty option for smaller closures such as meter covers, cabinet doors, and container latches. Because both types are plastic, they are non-sparking and suitable for use around electrical equipment and in areas where metal seals could cause damage or corrosion. The laser marking is black and sequential, which supports manual or automated recording of seal numbers at dispatch and receipt.

3G Electric supplies the UNIVERSEAL line as part of its industrial equipment catalog, with global shipping and logistics support. The catalog entries for these seals include SKU, MPN, pack quantity, strap or hasp dimensions, breaking strength, marking type, and marking color, so procurement and maintenance teams can match the seal to the closure and the record-keeping requirement. 3G Electric handles export documentation and freight coordination for international orders, and can quote mixed quantities across colors and seal types. For plant engineers and maintenance managers, the practical use is straightforward: select the seal family by strength and closure type, choose a color for visual identification, and record the sequential number at the point of application. The seals are consumables, so reorder quantities are typically driven by the number of points sealed per inspection cycle or per shipment.

Frequently asked questions

Common questions about UNIVERSEAL from 3G Electric.

What is the difference between UNIVERSEAL plastic strap seals and UNIVERSEAL plastic hasp padlock seals?

UNIVERSEAL plastic strap seals use a 6-inch strap with a 3/8-inch width and a 50 lb breaking strength. They are suited to applications where a longer, stronger tamper-indicating tie is needed, such as bagging, bundling, or closing larger container latches. UNIVERSEAL plastic hasp padlock seals use a 1-1/4 inch hasp and a 15 lb breaking strength. They are lighter-duty and fit smaller closures such as meter covers, cabinet doors, and panel latches. Both types are supplied in 50-piece packs, are laser marked in black with sequential numbering and the word 'Sealed', and are single-use.

What breaking strength do UNIVERSEAL strap seals and padlock seals have?

UNIVERSEAL plastic strap seals are rated to a 50 lb breaking strength. UNIVERSEAL plastic hasp padlock seals are rated to a 15 lb breaking strength. Breaking strength is the force at which the seal fails, so the 50 lb strap seal is the higher-strength option in the UNIVERSEAL range supplied by 3G Electric. The appropriate choice depends on the closure and the level of resistance required; for light closures such as meter covers, the 15 lb hasp padlock seal is typically sufficient, while the 50 lb strap seal is used where a stronger tie is needed.

Are UNIVERSEAL security seals numbered, and how is the marking applied?

Yes. UNIVERSEAL strap seals and hasp padlock seals are laser marked in black with sequential numbering and the message 'Sealed'. Laser marking is applied to the plastic, producing a legible number that remains readable on the seal. The sequential numbering allows each seal to be recorded against a specific asset, container, or shipment. In practice, the number is written on the dispatch or inspection record when the seal is applied and checked against the same record when the seal is removed. This supports tamper detection and reconciliation without relying on the seal alone.

What colors are available for UNIVERSEAL strap seals and padlock seals?

UNIVERSEAL plastic strap seals are available in colors including red, green, and yellow. UNIVERSEAL plastic hasp padlock seals are available in colors including blue, red, yellow, green, orange, and black. Color coding is a common way to distinguish routes, shifts, regions, or asset classes without changing the seal type. All colors in both families carry the same black laser marking with sequential numbering and the 'Sealed' message. Pack quantity is 50 per pack for both strap seals and hasp padlock seals. Availability of specific colors can be confirmed at the time of quotation.

What are the dimensions of UNIVERSEAL strap seals and hasp padlock seals?

UNIVERSEAL plastic strap seals have a 6-inch strap length and a 3/8-inch strap width. UNIVERSEAL plastic hasp padlock seals have a 1-1/4 inch hasp length. These dimensions determine what the seal can pass through or around. The 6-inch strap is long enough for many container latches, bags, and bundles, while the 1-1/4 inch hasp fits smaller openings such as meter cover tabs and cabinet latch holes. Both seal types are plastic and are supplied in 50-piece packs. Dimensional drawings or samples can be requested through 3G Electric for fit verification.

How does 3G Electric supply UNIVERSEAL security seals internationally?

3G Electric lists UNIVERSEAL strap seals and hasp padlock seals in its catalog with SKU, MPN, pack quantity, dimensions, breaking strength, and marking details. Orders can be quoted for mixed colors and seal types, and 3G Electric coordinates export documentation and freight for international shipments. Because the seals are consumables, buyers typically order in multiples of the 50-piece pack based on the number of sealing points per cycle. For plant engineers and maintenance managers, 3G Electric can provide the catalog data needed to standardize on a seal family and color scheme across sites, and can quote replenishment quantities against expected usage.
