5-Pack 1/8" Tube OD Bulkhead Union Push-to-Connect Pneumatic Air Fittings – Brass

Got a pneumatic setup?

These bulkhead union fittings from WIC Valve are what you need for running air lines through panels or enclosures.

It’s a 5-pack, so you’ve got spares.

They’re push-to-connect on both ends, so no tools required—just push your tube in and it locks.

Tube OD is 1/8 inch, which is about 3.18 mm.

The body is brass, so they’re durable and corrosion-resistant.

Straight shape, compact, and easy to install.

MPN is PBU-T1/8 if you need to look up more specs.

Great for pneumatics, air systems, or any project where you need a clean pass-through connection.
