American Casting and Manufacturing offers host of truck and tanker security seals for extensive transportation purposes. These come in different forms, including plastic seals, metal seals, high security seals, and cable seals, and offer various levels of protection. Not only are they able to keep cargo secure, but they can be manufactured to meet branding guidelines as well.
Trucks and tankers use different seal types depending on the specific application. Trailer doors are typically secured with bolt seals or heavy-duty strap seals. Tanker valves and hatches are sealed with cable or wire seals that thread through valve handles and fittings. Cab and equipment access points use lighter padlock or pull-tight seals. With over 30 in-stock models, the truck and tanker line covers every application from fuel tanker valves to refrigerated trailer doors.
A cable or wire seal is threaded through the tanker valve handle and locked, and the serial number is recorded on the bill of lading at the loading terminal. At delivery, the driver and receiver verify the number on the seal against the paperwork before the valve is opened. A broken seal or mismatched number is cause to stop the delivery, document the discrepancy, and report it to the dispatcher and terminal before any product is offloaded, protecting all parties from liability.
For tanker valves and fittings, adjustable cable seals in 14-inch or 24-inch lengths with cable diameters from 1/16 to 3/16 inch are the standard choice because they thread through valve handles and accommodate varying fitting sizes across different tanker configurations. For trailer door rods and hasps, a heavy-duty bolt seal or all-steel bolt seal provides the highest level of physical security and the most significant tool requirement for unauthorized removal.
Breaking strengths range from 25 lbs (11.3 kg) on lighter plastic seals up to 155 lbs on heavy-duty fixed-length cable and bolt seals. For tanker valve and hatch applications, a cable seal in the 110 to 155 lb range provides meaningful physical resistance against tampering during transit. For trailer door rods, a bolt seal provides the highest breaking strength and the greatest barrier to unauthorized removal.
Yes. The Barcoded Truck Seal (Model BCTS) and Barcoded Strap Seal (PS360-LBC) are specifically designed for truck and trailer applications. Most other models in the line are also available barcoded and numbered, allowing fleet operators to maintain an electronic log of every sealed load by driver, route, and delivery point and quickly identify any discrepancies when loads arrive with broken or mismatched seals.
The driver should not open the valve or proceed with offloading until the discrepancy is formally recorded. Note the broken or missing seal on the bill of lading with both the driver's and receiver's signatures. Photograph the affected valve and surrounding area, then report the incident to the dispatcher and loading terminal immediately. Depending on the product and applicable regulations, the carrier, shipper, and potentially the relevant regulatory authority may need to be notified before the tanker is unsealed.
Yes. Custom sequential numbering, company name, logo, and color options are available. Fuel distributors, chemical carriers, and food-grade tanker companies use custom-printed seals as part of their compliance and brand accountability programs, making unauthorized seal substitution immediately obvious to terminal staff, inspectors, and receivers who know what to look for on a legitimate delivery.
Minimum order quantities vary by seal type and whether custom printing is required. Many fleet operators order in volume given the daily seal replacement cycle across a full tanker or trailer fleet, and volume pricing applies. Sample orders are available so drivers and terminal staff can field-test models before committing to a program.
