3/8UNION
In stock · ships from Knoxville
A 3/8-inch union connector is a plumbing or pneumatic fitting that joins two separate lines of the same diameter, allowing easy disconnection for maintenance or repair without cutting the line.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
These are commonly used in air systems, fluid transfer, and gas applications, and are available in materials like brass, malleable iron, or push-lock acetal. A union is typically replaced when it leaks, corrodes, or when system modifications require a breakable connection point.
