Non-serviceable fluid coupling

摘要

A non-serviceable coupling (8) includes a body with a tube receiving end bore and a hose receiving end bore. The tube (13) includes a radial upset (26) with a seal (30) and spacer (32) supported on the tube (13). The outer cylindrical surface (27) of the tube (13) is press fit into the reduced diameter bore at the tube receiving end (12) to connect the coupling (8) to the tube (13). The coupling body (8) is crimped to the tube (13) and to the hose (14) to secure the hose (14) and tube (13) to the coupling (8). The tube (13) is axially restrained between the crimp and an annular wall (23) in contact with the tube end. In another embodiment, a second seal, outward of the upset is employed to prevent entry of contaminants.
