LKI-M – AIRflex® Straight Conduit Compression Fitting (Swivel Thread, Metric)
Metric swivel-thread straight conduit compression fittings for AIRflex® spiral conduits
LKI-M straight conduit compression fittings are designed for use with AIRflex® spiral conduits and feature a metric swivel-thread connection. The turnable threaded end allows the fitting and conduit to rotate independently after installation, helping reduce torsional stress where movement, vibration, or rotational repositioning may be present.
These one-part plastic fittings support secure conduit termination in industrial and equipment applications where controlled rotational movement is beneficial. LKI-M fittings are commonly used where the conduit may be subject to oscillation, multi-axis movement, or repeated repositioning during operation.
Designed for use with AIRflex® protective conduits including AIRflex-KUW-PVC-AS, AIRflex-KUW-PU-AS, AIRflex-K, and AIRflex-GRS, LKI-M fittings provide reliable conduit retention with IP54 ingress protection when installed in accordance with product specifications.
Select the correct fitting by matching the required metric thread size, conduit outside diameter, conduit type, and installation movement requirement.
- Temperature: -10°C to +110°C
- Ingress Protection: IP54
- Conduit Compatibility: AIRflex-KUW-PVC-AS, AIRflex-KUW-PU-AS, AIRflex-K, AIRflex-GRS

How to Choose the Right LKI-M Fitting
Choose the correct LKI-M fitting by matching the metric thread size, conduit outside diameter, AIRflex conduit type, and whether rotational movement or vibration is expected in the installation.
- Match the required metric thread size
- Match the conduit OD
- Confirm the correct AIRflex conduit type
- Use LKI-M where turnable thread movement helps reduce torsional stress
- Confirm the required ingress protection level
- Confirm suitability for dynamic or vibration-prone installations
Frequently Asked Questions about LKI-M Fittings
What is the LKI-M family used for?
LKI-M fittings are used to terminate AIRflex® spiral conduits into metric-threaded panels, enclosures, and equipment while allowing the threaded end to remain turnable in installations involving vibration, oscillation, or controlled conduit movement.
What does the swivel-thread design do?
The swivel-thread design allows the fitting’s threaded end to rotate independently of the conduit body after installation. This helps reduce torsional stress on the conduit and makes alignment easier in dynamic applications.
Which conduits are LKI-M fittings compatible with?
LKI-M fittings are designed for selected AIRflex® spiral conduits, including AIRflex-KUW-PVC-AS, AIRflex-KUW-PU-AS, AIRflex-K, and AIRflex-GRS. Conduit size and profile should always be matched to the fitting specification.
When should LKI-M be used instead of USK?
LKI-M is preferred where conduit movement, vibration, oscillation, or rotational adjustment may occur. USK is better suited to fixed installations where conduit movement is not expected and a traditional fixed compression lock is preferred.
What ingress protection do LKI-M fittings provide?
LKI-M fittings provide IP54 ingress protection when installed correctly and matched with the appropriate AIRflex® conduit.
