Abstract
A fluid handling body and a method of attaching extension tubes to the fluid handling body which effectively seals the tubes to the body in a simple manufacturing operation, reducing the number of manufacturing operations required while minimizing the possibilities of damage to the tubes or undesirably restricting the fluid flow path in the body or tubes. The method hereof is particularly advantageous where several tubes are to be attached to the body to produce a precise, leak-free component. The body includes a fluid flow passageway extending into one end and a saucer-like cavity in the other end. A plurality of bores extend through the body between the cavity and passageway. With the tubes received in the bores, a paste is applied in the cavity. The outer periphery of the body is heated, melting the paste in a single heating operation and effecting flow of the paste in the cavity into circumscribing relation about the tubes.
