Distribute Inch-Size Pneumatic Lines from a Plug-In Manifold
PKJ Series stem manifolds plug directly into a compatible push-to-connect port and distribute compressed air to multiple inch-size pneumatic tube branches. This can reduce the number of separate tees and adapters required in compact automation assemblies.
The push-in connections allow compatible polyurethane, nylon and other suitable pneumatic tubing to be installed quickly and removed for service when the circuit is safely depressurized.

Frequently Asked Questions
What is a stem manifold push-to-connect fitting?
It plugs into a compatible push-in port and provides multiple downstream tube connections.
What tubing is commonly used?
The source range identifies polyurethane and nylon pneumatic tubing as common materials.
What is the listed working pressure?
0–150 psi(g) / 10 bar(g).
Can it be used for vacuum?
The source specification lists vacuum duty to 29.5 inHg / 14 mbar(a).
Can the tubing be disconnected?
Yes. Compatible tubing can be released from the push-in connection after the system is safely depressurized.
Why use a manifold instead of several tees?
A manifold can create a cleaner, more compact distribution point with fewer separate connections.
Where are stem manifolds commonly installed?
They are used near valves, control panels, machine frames and pneumatic distribution points.
How do I choose the correct manifold?
Confirm host push-in size, outlet tube sizes, number of branches, required flow and operating conditions.
