Use Case |
Connect grooved main pipe to threaded branch pipe |
Two different connections. One fitting.
- Have you ever tried connecting a grooved main line to a threaded branch? It can be frustrating. You need adapters, maybe a flange, or even welding.
- Not anymore.
- This grooved threaded reducing tee is designed to solve that problem. It has grooved ends for the main pipe and a threaded outlet for the branch. A customer in the UAE contacted me last year for a fire sprinkler project. The main line was grooved, while the sprinklers were threaded. He was preparing to use multiple adapters. I suggested this tee instead. One fitting. Problem solved.
- The grooved threaded reducing tee is made of ductile iron. We cast it, apply anti-corrosion coating, and then machine the threads. Grooved sizes range from DN50 to DN300, and threaded outlets range from DN15 to DN100.
No Adapter Stacking. No Extra Leak Points.
- Every additional adapter increases the risk of leakage. This grooved threaded reducing tee eliminates three to four separate fittings in one solution. That means less installation work and fewer potential leak points.
- Jianzhi Group manufactures this product. We supply to over 130 countries and hold BSI and SNI certifications, ensuring smooth export clearance.
- Minimum order is 10,000 RMB. Mixed sizes are accepted. OEM branding is available with simple logo printing.
