RX e-tubes - Novel and extremely chip-proof

The troubleshooter for energy supply systems in the chip area - available in 4 sizes. Chips and dirt can affect the service life of cables and hoses significantly. With the RX system, igus® offers an extremely tight, but yet very easy to open plastic e-tube.

Snap-open along the outer radius

A smooth, curved outer contour prevents chip buildup

Circumferential injection-moulded "sealing lips"

No holes, cracks, undercuts

Series RX40 is IP40 tested (TÜV Saarland)

Interior separation and guide trough available

Concealed pin/hole connection and stops

"RBR" version available with bending radius on both sides

Typical branches of industry

Machine tools

All applications in the immediate chip area

Applications exposed to dust and dirt

General mechanical engineering


Chip tests in the igus® laboratory demonstrate the tremendous chip-proof properties of the igus® RX tube.


Chip-proof - for all types of chips and applications

e-chain® selection aids

You can find the right e-chain® quickly by entering concrete parameters and with the aid of a comparison table.

Assembly instruction

Dismantling / assembling a cover, replacing a chain link and assembling / inserting the RX tube.

Configure interior separation

Define cables, select chain and configure interior separation. Now also for RX tubes!

Application examples

Applications in various industrial sectors.

red dot 2011: honourable mention
for the RX40
iF-Design-Award for RX

ESD classification: Electrically conductive ESD/Atex versions on request
UL94-V0 classification on request
e-tubes available as special design with HT material for 850°C hot chips

Submersion test in water - Various tube types were submerged under water. The new RX tube needs over 30 seconds until it is filled up, thus proving its high leak tightness
