Abstract
A tubing coupler for mechanically and fluidly connecting two pieces of tubing. The tubing coupler has a first body portion with a pilot and a second body portion with a cavity in which the pilot is disposed when the tubing coupler is assembled. A fluid passageway through the first body portion and the pilot of the first body portion is in fluid communication with a fluid passageway through the second body portion and the cavity of the second body portion. Thus fluid flow is allowed through the coupler. A primary sealing device circumscribes the pilot of the first body portion and seals the space between the pilot of the first body portion and the cavity of the second body portion. A plate is disposed between the first body portion and the second body portion and defines an opening through itself through which the pilot of the first body portion protrudes. A secondary sealing device is disposed inside the periphery of the opening in the plate and surrounds a portion of the pilot. The secondary sealing device is elastically compressed between the first body portion and second body portion and acts as a back up for the primary seal.
