ABSTRACT:
Each of two sections of tubing (4) has a ferrule (8) swaged onto its end. The ferrule (8) forms an outwardly directed radial flange (12) and an axial extension (14) projecting axially outwardly from a peripheral portion of the flange (12). The sections (4) are coaxially aligned. A hollow spool (20) is positioned between the flanges (12) and within the extensions (14). Opposite radial end walls (26) and a center land (28) on the outer circumferential surface of the spool (20) form two recesses (30). An O-ring seal (34) is positioned in each recess (30). There is clearance between the spool (20) and both the flanges (12) and the extensions (14). The spool (20) floats on the seals (34) which are radially compressed between the recess walls and the extensions (14). A nut assembly secures the flanges (12) together.
