Bulkhead Connector KQ2E

The KQ2E bulkhead connector fittings from SMC are quick and easy to install into your pneumatic fittings. These KQ2E bulkhead connectors are also more compact in design which means that these connectors can be used within a confined space. Bulkhead connectors are designed to connect male thread tubing through a panel. 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
