RT16.01N-11.5NPT YBG201 Threading Insert
Precision 11.5 TPI Internal NPT Solution for High-Pressure Leak-Proof Sealing
Product Overview
"Looking for a reliable internal NPT insert that ensures a perfect 1:16 taper fit and airtight seal in stainless steel pipe fittings?"
The ZCC.CT RT16.01N-11.5NPT YBG201 is a specialized internal threading insert dedicated to 11.5 TPI NPT (National Pipe Taper) standards. As a Full Profile insert, it machines the complete thread form—crest and root included—ensuring the exact geometry required for critical pressure-tight connections.
Utilizing the YBG201 PVD Grade, this insert combines a high-toughness carbide substrate with a heat-resistant nc-TiAlN coating. It is engineered specifically for internal boring operations where chip control is difficult, excelling in General Steels (P) and Stainless Steels (M).
Key Features
- Exact 11.5 TPI Full Profile: Ensures perfect thread crests and roots for high-pressure sealing without the need for additional topping tools.
- YBG201 PVD Coating: Offers superior balance of wear resistance and edge toughness, preventing chipping during interrupted internal cuts.
- Optimized Taper Control: Precision-ground geometry ensures the 1° 47' taper is maintained consistently throughout the thread length.
- Enhanced Chip Evacuation: Designed to prevent chip clogging within the internal bore, ensuring a smooth, mirror-like thread surface.

Typical Applications
- 1" to 2" NPT internal pipe threads (Common 11.5 TPI range).
- Oil & Gas hydraulic fittings and adapters.
- Water treatment systems and pressure vessel couplings.
- Consistent performance in Stainless 304, 316, and Alloy Steels.
Performance Edge
The 11.5 NPT Full Profile geometry is essential for applications where the thread must be leak-proof. Because it machines the tooth crest, it ensures that the thread's major and minor diameters are perfectly balanced relative to the taper, reducing the risk of galling or poor sealing.
Verified User Performance
"Excellent dimensional control. Every internal NPT gauge passed without issue. The YBG201 grade is very stable in 316 stainless."
— Mark S., USA"The full profile cresting saved us an extra finishing pass. Clean threads even in deep bores."

Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
