Question by: Harold P on Feb 17, 2026, 8:05 PM

What size wrench do I need for these bulkhead unions? Looks like maybe 46mm?

Answer by: Customer Support on Feb 19, 2026, 6:01 AM

you got it. The flats on these fittings are 46mm across, so a standard 46mm wrench will do the trick.

got a bulkhead pass-through deal with DIN tube ends. is this one straight and threaded M36 x 2.0 on both sides?

Answer by: Customer Support on Jan 28, 2026, 4:14 PM

Built as a straight bulkhead union, it has M36 x 2.0 male DIN Tube connections on both sides, with side 1 and side 2 both called out as S25.

Question by: Hubert B on Aug 14, 2025, 8:19 AM

what size tubing does this bulkhead union work with? both sides are the same connection or different?

Answer by: Customer Support on Aug 15, 2025, 12:23 PM

Both sides run M36 x 2.0 male DIN Tube connections, so you're working with matching S25 fittings on each end. Same size all the way through, which keeps things straightforward when you're routing tube on both sides of a panel or bulkhead wall.
