This invention relates to the sealing and assembly of a container used to store and deliver ink to the printhead of an inkjet printer. It provides a robust solution to needs for today's products, such as replacing or repairing ink delivery systems. The inkjet pens have a container used to store and deliver ink to the printhead. The containment of the ink is usually at a partial vacuum of 0.5-9.0 inches of water column to prevent leakage of ink from the printhead. It is undesirable to allow ink to penetrate a seal between different pen parts that create this containment body, and it is also undesirable to allow air to intrude into the containment body through the seal.
