Tank Truck VB Dust Plug (TW Blank Plug)

The VB-type Tank Truck (TW) dust plug is designed to seal and protect female MK couplings when they are not actively connected to a hose or piping system. Operating like a male (VK) coupling, the VB plug is inserted into the MK coupling and locked firmly into place using the MK lever handle. It prevents external contamination such as dirt, moisture, and dust from entering the system, while also containing any residual fluid drips.

Key Features:

• Reliable System Protection: Keeps the internal surfaces and gaskets of the MK coupling safe from mechanical damage, environmental debris, and corrosion during transport.
• Quick & Tool-Free Operation: Features a specialized matching rim that engages with the MK locking handle, allowing for instantaneous manual sealing without specialized tools.
• Material Selection: Available in aluminum, brass, stainless steel (AISI 316), or lightweight polyamide (plastic) to suit specific requirements for weight, durability, and chemical compatibility.
• Standard Compliance: Manufactured in strict accordance with EN ISO 14420-6 (formerly DIN 28450) standards, ensuring a seamless fit with any standard MK female coupling.

Technical Specifications:

• Design: Compact blanking plug equipped with an eyelet for a safety chain to prevent loss during loading and unloading operations.
• Available Sizes: Standard industrial sizes including DN50 (2"), DN80 (3"), and DN100 (4").
• Sealing: Relies on the profile gasket located inside the mating MK coupling to achieve a tight, leak-free seal.

Applications: Installed on tank truck discharge valves, chemical pipeline ends, stationary storage tanks, and at the ends of terminal transfer hoses.
