A tubing interface (20) having an elongated tube (21), an elastomeric ferrule (24) and a support ring device (30) disposed around the ferrule (24). The ferrule (24) includes a bore (28) which is sized for receipt of the tube (21). The tubing interface (20) further includes a cap member (31) having an exterior surface (32), an opposed interior surface (33), and a tube receiving passage (35) extending therethrough. The receiving passage (35) is formed and dimensioned for axial sliding receipt of the tube member therethrough. The cap member (31) further includes a cup-shaped receiving recess (36) extending proximally from the interior surface (33), and is formed and dimensioned for axial receipt of the proximal end of the ferrule body member (25) and the support ring (30). When the cap member (31) is mounted to a valve apparatus (29), the support ring (30) and the elastomeric ferrule device (24) compressively cooperate with the cup-shaped recess (36) to form a fluid-tight seal between the tube port (22) and a co
