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."
— David L., Canada

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
