TW kobling type VK

TW coupling type VK is a variant of the TW coupling system with BSPP/G female thread and a simpler construction than MK type. The material is stainless steel with 16 bar working pressure. Three standard sizes (VK 50, 80, 100) cover the bulk of the tank truck installation range. Typically used in less critical TW applications where the MK type's dual-ring construction is not required.

Frequently asked questions

Difference MK vs VK?

VK is a simpler construction without separate clamping ring. MK has a dual construction with tank truck sealing ring and clamping ring giving extra robust sealing. Choose VK for standard installations; MK for critical tank installations.

For which stutsen?

VK fits VKST one-piece male couplings (SKU 5570) or TW male hose stutsen (5537). Cross-check your pipe connection configuration.
