got an L35 DIN tube port sitting open right now, is this cap the right one or am I off a size

Answer by: Customer Support on Jun 24, 2025, 11:41 AM

For an L35 DIN tube connection, this cap matches that sizing callout and is meant to seal an unused DIN tube port. The thread on the cap is female M45 x 2.0, so it is a fit when your port uses that DIN tube size and thread.

Use-case-first. This cap is designed for use with L35 sized DIN tubing, which corresponds to the tube outside diameter per DIN standards.

Got a DIN port on a hydraulic manifold that ain't being used right now, what size thread am I looking at to cap it off with this fitting?

Answer by: Customer Support on Feb 11, 2026, 6:13 AM

For an L35 DIN tube connection, the thread on this cap is M45 x 2.0 female. That's what mates up to the male port on your manifold. The cap itself is steel, 24mm long, and you'll need a 50mm wrench to snug it down proper.
