Plastic Steel Tee - FAQ Section
Q: What makes Plastic Steel Tee different from regular plastic tees?
A: Plastic Steel Tee incorporates steel fibers into the polymer matrix, providing significantly higher burst strength and impact resistance than standard plastic fittings. While maintaining all the corrosion benefits of plastic, our tee offers 3 times the pressure rating of conventional PVC tees.
Q: Can Plastic Steel Tee be used for hot water applications?
A: Yes, but with limitations. The Plastic Steel Tee performs optimally in temperatures up to 140°F (60°C). For short-term exposure (up to 4 hours), it can handle temperatures up to 180°F (82°C). We recommend consulting our technical specifications for continuous high-temperature applications.
Q: How should I install Plastic Steel Tee to ensure proper sealing?
A: For best results with Plastic Steel Tee:
- Clean and deburr all pipe ends before installation
- Apply thread sealant (Teflon tape or pipe dope) to male threads only
- Hand-tighten plus 1-1/2 turns with a wrench - never overtighten
- Align the tee branch correctly before final tightening
- For pressurized systems, conduct a hydrostatic test at 1.5x working pressure
Chemical Resistance Chart
| Chemical | Concentration | Temperature Limit | Resistance Rating |
|---|---|---|---|

| Sulfuric Acid | Up to 50% | 140°F (60°C) | Good |
| Sodium Hydroxide | Up to 30% | 180°F (82°C) | Excellent |
| Bleach (Sodium Hypochlorite) | Up to 15% | 100°F (38°C) | Good |
| Ethylene Glycol | 100% | 160°F (71°C) | Excellent |
Installation Guidelines for Plastic Steel Tee
- Always support piping on both sides of the Plastic Steel Tee to prevent stress concentration
- Maintain minimum 2" clearance from heat sources exceeding 200°F (93°C)
- For underground installations, use protective wrap in corrosive soils
- When transitioning between Plastic Steel Tee and metal pipes, use dielectric unions
- In vibration-prone applications, install vibration absorbers near the fitting

Additional Plastic Steel Tee FAQ
Q: Does Plastic Steel Tee require special tools for installation?
A: No special tools are required for Plastic Steel Tee installation. Standard pipe wrenches or strap wrenches work perfectly. However, we recommend using a torque wrench for critical applications to prevent overtightening. The recommended torque values are:
- 1/2": 15-20 ft-lbs
- 3/4": 20-25 ft-lbs
- 1": 25-30 ft-lbs
- 1-1/4" and larger: 30-35 ft-lbs
Q: What is the expected service life of Plastic Steel Tee?
A: Under normal operating conditions, Plastic Steel Tee has a projected service life of 25-30 years. Factors that may reduce lifespan include continuous exposure to UV radiation, temperatures exceeding recommended limits, or aggressive chemical environments. Our accelerated aging tests show less than 5% degradation after 10,000 hours at maximum rated pressure.
Q: Can Plastic Steel Tee be used for compressed air systems?
A: Yes, Plastic Steel Tee is approved for compressed air applications up to 150 PSI at temperatures below 120°F (49°C). For higher pressure air systems, we recommend our reinforced series which handles up to 300 PSI. Always install proper filters and dryers upstream to remove moisture and contaminants.
Maintenance Recommendations
- Inspect Plastic Steel Tee annually for signs of stress or deformation
- Check threaded connections for leaks every 6 months in critical applications
- Clean exterior surfaces with mild detergent - never use abrasive cleaners
- For chemical service, conduct more frequent inspections based on fluid aggressiveness
- Replace any fitting showing cracks, excessive wear, or thread deformation
