WPX Series Y-Type Tee User Guide

Product Introduction
The WPX Series Y-Type Tee is a high-quality three-way connector manufactured by WENK Pneumatic. It is specifically designed for pneumatic systems that require branching or merging of air lines. This product features a male threaded connection on one end for easy connection to other threaded components, and push-in connections on the other two ends for quick tube attachment, making it an ideal choice for creating branch connections in pneumatic control systems, automation equipment, and industrial air lines.

Product Features
-
Y-Type Design: Branches at a 45-degree angle, reducing air flow resistance and enabling efficient air distribution
-
Male Thread on One End: Features a male threaded design on one end for secure connection to female threaded components
-
Push-In Connections on Two Ends: The other two ends feature push-in designs for quick tube connection, saving installation time
-
Premium Materials: Constructed from brass with nickel plating, offering excellent corrosion resistance and durability
-
Multiple Specifications: Compatible with tubing diameters from 4mm to 12mm, with thread sizes including 1/8" to 1/2" NPT

Installation Preparation
Tools Required
- Pipe cutting tool (such as a pipe cutter or sharp scissors)
- Measuring tape or ruler
- Sandpaper or file (for removing burrs)
- Teflon tape or pipe thread sealant
- Appropriate size wrench
Materials Required
- WPX Series Y-Type Tee
- Compatible pneumatic tubing (such as polyurethane, nylon, etc.)
- Female threaded components to be connected (such as valves, cylinders, etc.)

Installation Steps
Tube Preparation
- Use a pipe cutting tool to cut the tube vertically, ensuring a clean, burr-free cut
- Gently sand or file the edge of the cut to remove any burrs or sharp edges
- Measure and mark the length of tube that needs to be inserted into the fitting (typically 2-3 times the tube diameter)
Thread Preparation
- Inspect the female threaded component to be connected, ensuring the threads are intact and undamaged
- Wrap an appropriate amount of Teflon tape (in a clockwise direction) or apply pipe thread sealant to the male threads of the Y-type tee
- Ensure the Teflon tape or sealant evenly covers the entire threaded surface, but not excessively to avoid airway blockage
Y-Type Tee Installation
- Align the male threaded end of the Y-type tee with the female threaded component and gently thread it by hand
- Use a wrench to tighten moderately, but be careful not to overtighten to avoid damaging the threads
- Ensure the Y-type tee is securely installed without any looseness
Tube Connection
- Insert the prepared tube straight into one of the push-in ports of the Y-type tee until it reaches the internal stop
- Gently pull the tube to confirm it is securely connected (the tube should not be easily pulled out)
- Repeat steps 1-2 to connect the tube on the other end
- After installation, check if all connections are secure and ensure there are no leaks

Usage Precautions
-
Working Pressure: Use within the specified working pressure range of the product, avoid overpressure operation
-
Working Temperature: Avoid use in extreme temperature environments, refer to product technical specifications
-
Fluid Type: Only suitable for compressed air systems, avoid use with other gases or liquids
-
Regular Inspection: Periodically check if the connections are secure and if there are any leakage phenomena
-
Avoid Impact: Prevent the fitting from being subjected to severe impact or vibration, which may cause loose connections
-
Proper Disassembly: If disassembly is required, first release system pressure, then press the release collar on the push-in port while pulling out the tube

Troubleshooting
-
Insecure tube connection
- Possible Cause: Uneven tube cut or burrs
- Solution: Re-cut the tube, ensure a clean, burr-free cut
-
Leakage at threaded connection
- Possible Cause: Insufficient sealing material or not tightened enough
- Solution: Re-wrap with Teflon tape or apply sealant, tighten moderately
-
Leakage at push-in connection
- Possible Cause: Mismatched tube size or not fully inserted
- Solution: Confirm tube size matches, ensure fully inserted to the stop
-
Y-type tee damage
- Possible Cause: Over-tightening or using improper tools
- Solution: Replace with a new fitting, use appropriate tools and avoid over-tightening
