Our NPT and BSP Service Tees are engineered for high-performance plumbing and industrial piping systems. Designed to connect three pipes at a strategic junction, these service tees feature a dedicated branch connection that extends from the side, facilitating seamless fluid diversion from main lines to secondary pipes. This design is critical for efficient system maintenance, repair, and monitoring without disrupting the primary flow.
Manufactured from premium ASTM A197 malleable iron, these fittings are available in both Black and Hot-dipped Galvanized finishes to ensure maximum durability. Whether you require NPT or BSP threading, our service tees provide a leak-proof, robust connection suitable for a wide range of pressure environments, combining 30 years of casting expertise with strict international quality standards.

Frequently Asked Questions
NPT (National Pipe Tapered) is primarily used in North America, while BSP (British Standard Pipe) is common in Europe and Asia. We provide both to ensure compatibility with your regional piping standards.
Hot-dipped galvanizing creates a thick, metallurgical bond of zinc (ASTM A 153) that acts as a sacrificial barrier, preventing the underlying malleable iron from rusting in corrosive environments.
Yes, our fittings are manufactured to ASTM A197 standards, providing the structural strength required for various industrial plumbing and pressure-bearing systems.
Our standard delivery time is approximately 35 days upon receipt of the advanced payment, ensuring quality casting and surface treatment.
While our standard range is 1/4" to 4", we have over 30 years of casting experience and can discuss custom specifications based on your project's technical requirements.
We support TT (Telegraphic Transfer) and L/C (Letter of Credit), typically requiring a 30% advance payment with the balance due before shipment.
