O-ring face seal (ORFS) Connectors shown here can be used with tubing or hose as shown below meeting ISO 8434-3. See ISO 12151-1 for applicable hose fittings.
Connectors and adjustable stud ends have lower working pressure ratings than nonadjustable stud ends. To achieve a higher pressure rating for an adjustable connector, a combination of straight stud connector (SDS) and a swivel elbow connector (SWE), as shown in Figure 1, can be used.
Figures 1, 2 and 3 show typical connections with O-ring face seal connectors.
