1/4 in. Compression Union with #26003
Overview
The Midland 26064 is a solid brass captive-sleeve compression union that joins two 1/4 in. compression tubes in a straight inline run. It ships with #26003 captive sleeve nuts so the brass sleeves stay attached for fast, leak-tight assembly with no soldering or threading. The all-brass body suits potable water, instrument air, fuel oil, and chemical-metering tubing runs.

Frequently Asked Questions
Does the 26064 come with sleeves and nuts?
Yes. It includes #26003 captive sleeve nuts on both ends, so the brass sleeves stay captured for quick assembly.
What tubing OD does it fit?
It is sized for 1/4 in. OD tubing on both ends as a straight union.
Can I use it for chemical metering lines?
Brass works well with water, oils, and many treatment chemicals. Confirm chemical compatibility before use on aggressive media.
Do I need pipe dope on a compression joint?
No. Compression seals on the ferrule, not the threads, so thread sealant is not required on the compression side.
