WPB Series T-Type Straight Tee Threaded Fitting User Guide
Product Introduction
The WPB Series T-Type Straight Tee Threaded Fitting is a high-quality pneumatic connection component manufactured by WENK Pneumatic, designed for branch connections in compressed air systems. This fitting features a T-shaped structure with quick-connect ports on two ends and a threaded port in the center, allowing for fast and reliable connection of air tubes with different diameters and threaded pneumatic components.
Constructed from high-strength PBT plastic body and nickel-plated brass threaded parts, this product offers excellent pressure resistance, corrosion resistance, and a long service life. It is suitable for various pneumatic systems, including industrial automation, mechanical manufacturing, packaging equipment, and other fields.
Installation Guide
Preparation Before Installation
- Confirm that the required fitting specifications match the tube diameter and thread size
- Check that the fitting is intact without cracks, deformation, or other defects
- Prepare necessary tools: tube cutter, sandpaper or knife (for processing tubes)
- Ensure a clean working environment to prevent dust and impurities from entering the pneumatic system
Tube Connection Steps
- Use a tube cutter to cut the tube to the required length, ensuring a flat and perpendicular cut
- Gently remove burrs from the tube cut using sandpaper or a knife
- Clean the inner and outer walls of the tube to ensure no dust, oil, or other impurities
- Press the release ring (black or blue part) of the fitting
- Insert the tube straight into the fitting until it can no longer be inserted
- Release the release ring and gently pull the tube to confirm a secure connection
Threaded Connection Steps
- Check that the threaded interface is clean and undamaged
- For PT (taper pipe threads), wrap an appropriate amount of Teflon tape around the threads (clockwise direction)
- Align the threaded pneumatic component with the threaded interface of the fitting
- Gently screw in by hand to ensure proper thread engagement
- Use a suitable tool (such as a wrench) to tighten moderately, but do not over-tighten to avoid damaging the threads
- Check that the connection is secure and leak-free
Usage Precautions
Safety Precautions
- Ensure the system is depressurized before installation to avoid injury from high-pressure gas
- Select fitting specifications that match the working pressure
- Avoid use in environments with corrosive gases, liquids, or high temperatures unless the product is specifically rated for such conditions
- Regularly check the connection status of the fitting to ensure no loosening or leakage
- When disconnecting the tube, always press the release ring before pulling out the tube to avoid forcefully pulling and damaging the fitting or tube
Maintenance
- Regularly inspect the fitting appearance; replace promptly if there are cracks, deformation, or other abnormalities
- Keep the fitting clean to avoid accumulation of dust, oil, and other impurities
- If impurities are found inside the fitting, gently blow them out with compressed air
- Fittings not in use for a long time should be stored in a dry, clean environment, avoiding direct sunlight and high temperatures
Troubleshooting
Common Problems and Solutions
-
Tube connection is not secure or easily falls off
- Cause: The tube cut is not flat or has burrs; the tube size does not match the fitting
- Solution: Cut the tube again to ensure a flat cut; replace with matching tube or fitting
-
Leakage at threaded connection
- Cause: Threads not tightened; improper or insufficient Teflon tape wrapping; damaged threads
- Solution: Tighten the threads moderately; re-wrap with Teflon tape; replace damaged fitting
-
Fitting leaks air
- Cause: Tube not fully inserted; tube cut not flat; damaged internal seal of the fitting
- Solution: Reinstall the tube, ensuring full insertion; re-cut the tube; replace with new fitting
-
Cannot insert tube into fitting
- Cause: Tube size too large; release ring not fully pressed; impurities inside the fitting
- Solution: Replace with appropriate size tube; ensure release ring is fully pressed; clean inside of fitting
