SMC 10-KQN12-99 | Clean Room Metric One-Touch Fitting KQN Series Nipple 12mm Tube OD Tube-to-Tube Straight Connector Pack of 5
SMC
$19.65
The SMC 10-KQN12-99 is a clean room specification metric-size one-touch fitting from the KQN series, configured as a nipple (straight tube-to-tube connector), sold in a pack of 5. Part number decoded: KQN = one-touch nipple, 12 = 12mm tube OD, 99 = nipple configuration code. The 12mm tube OD is one of the larger standard metric sizes, used for high-flow main supply lines, large-bore actuator connections, and trunk distribution runs in clean room pneumatic systems.
The 12mm KQN nipple connects two 12mm tube ends inline with minimal body length, maintaining a compact connection profile. At 12mm tube diameter, flow capacity is approximately four times that of a 6mm tube, making this the preferred size for main airline supply runs that feed multiple downstream devices through branch fittings. In clean room equipment, 12mm tubes typically serve as the primary supply backbone from the air preparation unit (FRL) to the first distribution point.
The KQN12-99 is the next size up from the KQN10-99 (10mm) in the nipple series. For the largest standard metric nipple, KQN16-99 covers 16mm tube OD. For inline connections requiring a longer body, the KQ2U12 union provides additional tube separation. For reducing inline connections between 12mm and smaller tubes, the KGR series (stainless) or KQ2R series (brass) provide reducing nipple alternatives. Sold in a pack of 5. Clean series (10-) fluorine grease, Particle Grade 1. RoHS compliant.
