Product Description

This product is the Heewework HW adapter T - type pipe fitting, which adopts a composite design of a brass nickel - plated metal port and a PA66 + glass fiber flame - retardant plastic sphere:

• Structural Design: T - shaped three - way branching structure. The metal port integrates NPT threads (accuracy ±0.05mm), and the plastic sphere has a red UV - resistant coating on its surface.
• Core Functions: Applicable to fire sprinkler systems, industrial pipelines, and HVAC systems, providing shock resistance, corrosion resistance, and high - load support.
• Certification Standards: Passed the UL94 V - 0 flame - retardant certification and ISO 16750 - 3 vibration test.

Core Values

• Safety and Reliability: Double - seal design reduces the leakage rate by 90%, and it shows no corrosion after a 96 - hour salt spray test.
• Efficient Operation and Maintenance: The red marking shortens the fault - location time by 40%.
• Cost Optimization: The composite material replaces the all - metal solution, reducing the unit cost by 55%.
