got a kobelco line with an L22 special tube end, is this nut the right one for it?

Answer by: Customer Support on Mar 6, 2026, 8:51 AM

For a Kobelco hydraulic line setup that uses an L22 special tube end, this nut matches that side 1 size and type, and it uses an M30 x 1.5 female metric thread.

Got a Kobelco machine that needs a new tube nut on one of the hydraulic lines. This one here say it takes an L22 special tube end, is that a pretty specific fit or will standard metric tube ends work with it?

Answer by: Customer Support on Jan 21, 2026, 9:27 AM

The L22 special designation means this nut is built for a specific tube end size used in Kobelco hydraulic assemblies. Standard metric tube ends won't seat correctly in it. You'd need the matching L22 special tube end to get a proper connection. It's a purpose-built component for Kobelco line work, not a general-use fitting.
