Will this plug work to cap off a Kobelco tube? I'm working on a hydraulic system, and need to seal it off.

What size wrench do I need to run this plug in, and how long is the body on it?

Answer by: Customer Support on Jul 31, 2025, 6:54 AM

The wrench flats measure 38mm across, so a 38mm wrench is what you want on hand. Body length comes in at 28.7mm, which keeps it compact enough for tight quarters in most hydraulic panels and valve blocks.

got a kobelco tube port that needs capped off, is this the right plug or am i gonna fight it

Answer by: Customer Support on Dec 22, 2025, 3:39 PM

For a direct fit, the connection needs to be a Kobelco type tube port with an M30 x 1.5 male thread requirement on the L22 Special side. This plug is built for that exact callout, so it’s meant to terminate or cap that style of Kobelco tube connection.
