Threaded Pipe Fittings
- Reliable Sealing: Tapered threads and precise machining ensure tight, leak-resistant joints in high-pressure piping systems.
- Wide Compatibility: Supports multiple materials and thread standards for integration with existing industrial, commercial, and utility pipelines.
- High Pressure Rating: Designed for 2000 lb, 3000 lb, and 6000 lb service classes in demanding environments.
- Full Size Range: Covers common nominal pipe sizes from 1/8″ to 4″ NPS for flexible system design.
- Easy Installation: Threaded connections allow quick assembly, disassembly, and modification without welding operations.
