Compact Series
Compact One-Touch Fittings Specification Overview
Compact one-touch fittings are a smaller-sized series of one-touch fittings mainly used in pneumatic systems with limited installation space or dense piping layouts.
Compared with regular one-touch fittings, compact fittings use a smaller fitting body, allowing pneumatic tubing to be connected to equipment ports or other pneumatic components within limited installation space.
The tube connection end of the compact series is also selected according to the tubing outside diameter. The series is available in Ø3, Ø4, and Ø6 mm tube sizes. Ø4 and Ø6 mm are also available in the regular metric series, and the main differences between the two series are the fitting body size and the installation space required.

Compact One-Touch Fittings Specification and Type Selection
Compact one-touch fittings are selected according to tube size, thread specification, connection type, fitting shape, installation space, and compatible tubing.
The tube connection end should match the outside diameter of the pneumatic tubing used. If the fitting has a threaded end, the thread specification of the equipment, valve, or pneumatic component port should also be confirmed.
