Using SMC speed controls with built in one-touch fittings minimizes installation time, reduces mounting height and enables a more compact machine design. These speed controls allow the body to be rotated to facilitate simple installation. Available in thread sizes from M3 to 1/2 in both inch (NPT) and metric R(PT) and with tube sizes from 3.2mm to 12mm OD (metric) and 1/8 to 1/2 OD (inch) and with optional elbow and universal style (increased flexibility) and meter-in and meter-out, these speed controls are designed to meet most applications.
