Cargo Tank Lid Packing (P105 Style)

At Kriloha Ltd., we recognize that in global maritime logistics, “Vapor Containment” is a matter of both safety and environmental compliance. A leaking cargo lid isn’t just a maintenance issue; it’s a regulatory risk. The Kriloha Cargo Tank Lid Packing (P105 Style) is our engineered answer for “High-Cycle” marine sealing. As a premier provider of industrial seals, Kriloha Gaskets has mastered the Co-Extrusion Braiding technology required to fuse a chemical-proof PTFE skin with a resilient rubber heart.

The engineering of our P105 series is based on Compensatory Sealing. Large tank lids often suffer from slight warping or uneven bolt tension. At Kriloha, our internal rubber core provides a “constant-energizer” effect. When the lid is clamped down, the rubber compresses, pushing the PTFE jacket outward with uniform pressure. This ensures a “Bubble-Tight” seal even if the lid isn’t perfectly flat. We utilize a high-density PTFE yarn that is pre-stretched to prevent “cold flow,” ensuring the packing retains its dimensions even under the weight of heavy steel hatches.

Manufacturing this packing at Kriloha involves strict Bonding Verification. We ensure the PTFE jacket is tightly locked around the core so it won’t “bunch up” or slide during the frequent opening and closing of the tank. Whether you are managing a fleet of chemical tankers or a battery of ISO containers, Kriloha P105 Cargo Tank Lid Packing provides the chemical invincibility and mechanical agility your operations demand. By choosing Kriloha Ltd., you are investing in a “Zero-Leak” technology that protects your cargo, your crew, and the environment.

Primary Use Cases

Chemical Tankers: Sealing hatch covers and manways handling a rotating variety of aggressive liquid chemicals.
Product Tankers: Providing a vapor-tight seal for refined petroleum products and solvents.
Food-Grade Transport: Sealing tanks carrying vegetable oils, juices, and other consumables where FDA-grade purity is required.
ISO Tank Containers: The industry standard for the manhole gaskets of intermodal containers used for global chemical transport.
Storage Tank Roofs: Utilized in land-based chemical storage facilities for primary lid and access port sealing.

FAQs

Why use a Rubber Core instead of solid PTFE?

Solid PTFE has poor “memory.” Once crushed by a heavy lid, it stays flat. The Rubber Core allows the packing to recover its shape every time the lid is opened, significantly extending the service life of the seal.

Is this packing compatible with all chemicals?

The outer PTFE jacket is compatible with almost everything. However, you should ensure the core material (Silicone or EPDM) is suitable for the operating temperature. For most standard marine cargoes, Kriloha P105 is a universal solution.

How do I join the ends for a large tank lid?

For a secure, leak-proof joint, Kriloha recommends a Scarf Joint (cutting both ends at a 45° angle) and using a specialized PTFE-compatible adhesive or heat-sealing the PTFE jacket ends together.

How do I measure for a replacement seal?

You need the Width and Thickness of the groove in the tank lid. Because this packing is square, it is often specified as a single dimension (e.g., 25mm x 25mm).

What is the “Sunwell P105” equivalent in your catalog?

Kriloha Gaskets manufactures a direct high-performance equivalent to the P105, often referred to as our Marine-Grade Multi-Core PTFE Packing. It meets or exceeds all international maritime standards for cargo containment.
