Din2353 Series Ll Cutting Ring

Description & Features

Sized at LL08 with an M12 x 1.0 thread callout, this steel cutting ring is designed for use in DIN 2353 Series tube fittings. At 9.5mm in length, it functions as a precision compression component that bites into the outer wall of the tube during assembly to create a reliable, leak-resistant seal without welding or flaring.

The Din2353 Series LL Cutting Ring is manufactured by Adaptall and suits hydraulic tube connections where DIN-standard compression fittings are specified. Steel construction provides the hardness needed for effective ring deformation during installation, making it well suited to high-pressure hydraulic line assemblies in industrial equipment and mobile machinery.

Reckon this would work on my hydraulic lines? Just need somethin' that'll hold up.

Primarily, this cutting ring is designed to create a secure, leak-resistant seal in DIN 2353 series tube fittings, so as long as your lines are to that spec, it should do the job. The steel construction is plenty durable for high-pressure hydraulic applications.

Got a tube fitting assembly I'm trying to match up, this a steel ring or some kind of coated material?

Answer by: Customer Support on Feb 3, 2026, 6:31 AM

Steel construction all the way through. That hardness is what lets the ring deform and bite into the tube wall properly during assembly, which is how it creates a leak-resistant seal. No coating mentioned, just straight steel.

got a din 2353 LL08 setup, is this the right cutting ring for an M12 x 1.0 nut?

Answer by: Customer Support on Jun 7, 2025, 10:07 AM

For DIN 2353 Series tube fittings, the LL08 cutting ring with an M12 x 1.0 thread callout matches that size callout. It is the compression ring style used in DIN-standard tube connections.
