Single Line Transfer Line Couplings for Simple Connections
The single couplings consist of two main components: the robust coupling housing and the precision-manufactured coupling insert. A practical union nut or clamping ring enables easy coupling and uncoupling of the insert from the housing for maximum ease of operation.
Discover the technical details, available designs, and components of our SingleLine transfer line couplings for your application.
SingleLine

Optimized Design for Minimal Heat Ingress
WEKA Single Line couplings for cryogenic technology feature a thermally optimized design that keeps heat ingress to cryogenic fluids minimal. This thoughtful construction ensures optimal efficiency in critical cryogenic applications.
All components – housing, insert, blind inserts, or blind plugs – are available as individual parts and can be procured separately at any time. This enables flexible inventory management and cost-effective maintenance.
Our Single Line couplings are available in various special designs: for horizontal use, with high-voltage insulation, or with integrated ball valve for extended functionality.
