Din2353 Cutting Ring

Description & Features

Designed to DIN 2353 standards, this steel cutting ring from Adaptall is sized for L18 tube connections with an M26 x 1.5 thread callout and a 10mm length. It functions as a compression-style sealing component used in hydraulic tube fittings, where the ring bites into the outer wall of the tube to form a reliable, leak-resistant connection.

Manufactured in steel, the Din2353 Cutting Ring is suited for high-pressure hydraulic tube assemblies common in industrial and mobile equipment. The L18 designation corresponds to an 18mm tube OD, and the M26 x 1.5 thread ensures compatibility with standard DIN 2353 fitting bodies. This component is typically used alongside a fitting body and compression nut to complete a tube end assembly.

got an 18mm DIN tube setup, is this the right cutting ring for it or am i off a size

For an L18 DIN 2353 tube connection, this ring is the matching size. L18 corresponds to an 18 mm tube outside diameter, and it pairs with DIN 2353 fitting bodies that use an M26 x 1.5 thread callout.

Got an 18mm tube I'm trying to get sealed up on a hydraulic line. This cutting ring gonna work for that size?

Answer by: Customer Support on Jan 13, 2026, 7:56 AM

the L18 designation on this ring is built specifically for 18mm OD tube. The M26 x 1.5 thread callout matches standard DIN 2353 fitting bodies, so as long as you're working with that tube size and a compatible DIN 2353 assembly, you're in the right place. You'll need a fitting body and compression nut to go along with it to complete the connection.

This cutting ring is designed for L18 tube connections, which means it's made for tubing with an 18mm outer diameter. It's compatible with standard DIN 2353 fitting bodies with an M26 x 1.5 thread.
