Low friction ring | I-TECH® Dynamic Use


I-Tech® Nodusfactory low-friction rings are self-lubricating, very light and resistant to dynamic friction.

They can be used in a wide range of dynamic applications with all types of ropes, they have a longer lifetime than metal and are 80% lighter!

+/- 6900 hours under continuous friction

+/- 200,000 halyard transmissions, tacking, sail trimming, etc.

The best glide isn't smooth!

Material: I-TECH | Lubricating thermoplastic polymer (recyclable)

Nodus & Tip

I-Tech® Low Friction Rings have a non-adhesive surface condition due to their production design and the material used. Friction is dynamic without energy loss.

The contact surface creates an angle of friction that limits adhesion at the beginning of the maneuver and improves sliding performance.

I-Tech rings for dynamic use are 20% lighter and 20% stronger! 

Coefficient of friction of the I-Tech PO 0.18 compared to aluminum 1.35 with Max lubricant treatment 0.30...
