Transfer Line Couplings for Flexible System Connections

Johnston couplings, also known as bayonet couplings, enable separable connections between vacuum boxes or vacuum vessels and flexible transfer lines. These robust transfer line couplings ensure reliable fluid transfer while maintaining vacuum insulation.

Proven Bayonet Technology for Critical Applications
Our transfer line couplings are available with one or two fluid lines and offer maximum flexibility for various system configurations. The vacuum-insulated design minimizes thermal loads and ensures optimal performance in cryogenic applications.
The proven bayonet technology enables quick and secure connections without compromising sealing integrity. These bayonet couplings are specifically developed for use in demanding environments where reliable separable connections are essential.
