Abstract
A fluidic coupling device includes a housing, and a piston, spring, and cap insertable in the housing. The spring includes a stack of spring washers and is compressible between the cap and the the piston. The cap is threadedly engageable with the housing and movable into contact with the spring. The device may be coupled to a component in a sealed manner by inserting a ferrule between the piston and the component, inserting a conduit through the housing and into the component, and threadedly engaging the housing with the component, thereby compressing the spring and translating the piston against the ferrule. The device may enable coupling to be done manually, with minimal variation in compressive loading. The piston and spring may desensitize the device to thermal cycling effects, reducing the need for retightening.
