• Full 1"-2" Professional Pipe Threading Die Set – ANSI B1.20.1 Certified NPT/NPTF Threads Designed for heavy-duty SCH40/80 pipes, this 4-die set (1-1/8", 1-1/4", 1-1/2", 2") delivers precise NPT/NPTF threading with industrial-grade durability, cutting 3000+ threads per die.
• 47745 (Economy) vs. 47770 (Industrial) Model Comparison–High-Speed Alloy vs. Molybdenum Reinforced.The 47745 (2-year warranty) features high-speed alloy steel for light repairs and DIY plumbing jobs. The 47770 (2-year warranty) has a molybdenum-reinforced core, offering 35% higher fatigue resistance for demanding oil/gas pipe threading.
• Military-Grade Heat-Treated Steel – 1800 PSI and 2500 PSI (47770) Pressure RatingsThe economy 47745 handles 1800 PSI for HVAC and plumbing repairs, while the industrial 47770 withstands 2500 PSI for high-pressure oilfield and industrial use.
• ASTM A519 Pressure-Tested – Anti-Rust Coating for Longevity and Precision Threads Rigorous ASTM testing ensures leak-free threading. Corrosion-resistant coating extends tool life in wet/humid conditions, while precision-cut teeth prevent slippage and seal failure.
