AirTAC One-Touch Fittings and Push In Fittings Guide
Compare AirTAC one-touch fittings, AirTAC push in fittings, and compatible straight, elbow, branch, and tee fitting structures by thread, tube OD, and routing direction before you bundle them into a valve and tube quotation.
What This Fittings Category Helps You Solve
This page is for buyers who need to match thread, tube size, and routing structure before finalizing a cleaner pneumatic layout.
Straight Connections
PC fittings connect tube directly to threaded ports in the most direct layout.
Direction Changes
PL elbow fittings are useful where routing needs a turn at the connection point.
Branch Layouts
PB and PE structures support branch and tee routing where the line splits.
Use brand and supply paths to narrow fitting sourcing faster
Fittings can follow original-brand continuity, compatible supply, or guide-based replacement logic depending on the RFQ goal.
AirTAC Fitting Path
Use this path when the buyer requests original-brand continuity or known AirTAC references.
HKQD Compatible Path
Use this path when thread, tube OD, and routing fit matter more than original-brand continuity.
Replacement Guide Path
Use guides to compare structures and fit logic before compatible quotation.
Compare the Main Fitting Structures
| Series | Structure | Main Function | Common Sizes |
|---|---|---|---|
| PC Series | Straight male connector | Connect tube to a threaded port | 4 to 16 mm |
| PL Series | Male elbow connector | Change routing direction at the port | 4 to 16 mm |
| PB Series | Male branch tee | Create a threaded branch connection | 4 to 12 mm |
| PE Series | Union tee | Tube-to-tube branch routing | 4 to 12 mm |
Where These Fittings Are Commonly Used
Valve and Cylinder Connections
Build cleaner air paths between actuators, valves, and machine ports.
Compact Routing
Use elbow and tee structures where installation space is more restricted.
Maintenance and Replacement
Quickly match common fitting structures in MRO and line-repair work.
Bundled Orders
Combine fittings with tubing and valves in one more practical quotation.
What Buyers Usually Confirm Before RFQ
- Confirm tube outer diameter, thread type, and installation direction first
- Decide whether the fitting is straight, elbow, tee, or branch structure
- Check compressed air, vacuum, and routing conditions in the machine
- Prepare fitting quantity and whether valves and tubing should be quoted together
Best Inputs to Send
For faster matching, send thread size, tube OD, fitting structure, quantity, and whether the order should be bundled with tubing or valves.

Contact UsQuestions Buyers Ask Most Often
How do I choose between PC, PL, PB, and PE fittings?
PC is straight, PL is elbow, PB is a threaded branch tee, and PE is a union tee for tube-to-tube connection.
What tube sizes are commonly supported?
Common tube outer diameters include 4 mm, 6 mm, 8 mm, 10 mm, and 12 mm depending on the fitting series.
Can these fittings be used for vacuum as well as compressed air?
Many push-in fittings can be used for both vacuum and compressed air within the rated pressure range.
