got a bulkhead pass-through spot on my panel. is this the straight union with m26 x 1.5 male ends on both sides?

Answer by: Customer Support on Oct 12, 2025, 6:15 AM

For a straight bulkhead union setup, this one matches that layout. It uses M26 x 1.5 male DIN tube connections on both sides, so it is set up to pass through a bulkhead and connect DIN tube fittings on each side.

Both sides on this thing are M26 x 1.5 male DIN tube fittings, right? Just want to make sure before I go cutting into my line.

Answer by: Customer Support on Sep 18, 2025, 8:41 PM

Correct on both counts. Each side uses an M26 x 1.5 male DIN tube connection, so you're working with matching thread specs all the way through. The straight configuration means there's no angle or offset to account for, just a clean inline path from one side to the other. SKU 5040L-18 is the part number if you need to reference it for your records.
