Plug-in Reducer KQ2R
The KQ2R plug-in reducer fittings from SMC are quick and easy to install into your pneumatic fittings. These KQ2R plug-in reducers are also more compact in design which means that these connectors can be used within a confined space. Plug-in reducers are designed to change the size of one-touch fittings. The new KQ2 range of products are lighter than previous models and have the advantage of improved insertion and removal forces.
Can be used under a wide range of pressures from a low vacuum to 1MPa
Low force required for fitting and removal
Compact dimensions for use within smaller spaces
