Tank Truck MB Caps

Tank Truck MB Dust Cap (TW Blank Cap)

The MB-type Tank Truck (TW) dust cap is designed to cover and protect male VK couplings when they are not connected to a hose or piping system. Operating like a female (MK) coupling, the MB cap features an integrated locking lever that seals tightly over the VK part, preventing contamination from dirt, moisture, or dust, and containing any residual fluid drips.

Key Features:

• Reliable Protection: Keeps the sealing surfaces of the VK coupling safe from mechanical damage, corrosion, and environmental debris during transport and storage.
• Quick & Tool-Free Operation: Equipped with a robust locking handle, the cap can be tightly secured or removed manually in seconds without specialized tools.
• Premium Materials: Available in aluminum, brass, or stainless steel (AISI 316) to meet specific requirements for weight, chemical resistance, or non-sparking safety.
• Standard Compliance: Manufactured according to EN ISO 14420-6 (formerly DIN 28450) standards, ensuring a perfect fit with any standard VK male coupling.

Technical Specifications:

• Design: Compact blanking cap with a locking lever and an eyelet for a safety chain to prevent the cap from being lost.
• Available Sizes: Standard industrial sizes including DN50 (2"), DN80 (3"), and DN100 (4").
• Seals: Supplied with NBR, Polyurethane (PUR), or Hypalon/Viton profile gaskets depending on chemical compatibility.

Applications: Installed on tank trucks, chemical storage vessels, stationary discharge manifolds, and port terminal loading systems.
