RT16.01W-11.5NPT YBG201 Threading Insert
Precision 11.5 TPI NPT Tapered Pipe Threading Solution for Multi-Material Applications
Product Overview
"Which threading insert is most reliable for leak-proof 11.5 TPI NPT tapered threads on hydraulic fittings and pressure vessels made of steel or stainless?"
The ZCC.CT RT16.01W-11.5NPT YBG201 is a specialized external threading insert designed for NPT (National Pipe Taper) 60° standards. Featuring the YBG201 Grade, this insert uses a multi-layered PVD coating that provides a high-toughness substrate for stable machining.
Engineered specifically for 11.5 Threads Per Inch (TPI), its partial profile (PB) ensures the necessary clearance and precision for tapered sealing threads. The YBG201 grade is the "versatile workhorse," offering excellent wear resistance and thermal stability across a wide range of ISO P (Steel) and ISO M (Stainless Steel) materials.
Key Features
- YBG201 Universal Grade: A perfect balance of hard coating and tough carbide, ideal for small to medium batch production where material types vary.
- Accurate 60° NPT Profile: Precision ground to meet strict ANSI/ASME B1.20.1 standards for tapered pipe threads, ensuring perfect metal-to-metal sealing.
- PVD Multi-Layer Coating: Specialized PVD process reduces friction and heat build-up, significantly extending tool life in alloy steels.
- Edge Stability: Designed to maintain edge sharpness even under the unique radial pressures of tapered threading cycles.

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.
