NTF66 – Navtek Flaring Tool 3/4″ Max OD – Precise Flaring Every Time

The Foundation of Every Leak-Free Connection

A quality flare is the foundation of a leak-free refrigerant connection — and the Navtek NTF66 Flaring Tool is designed to deliver one, every single time. With axial spacing and a patented rivet connection, the NTF66 produces consistent, accurate flares across six common tubing sizes, making it an essential tool for every HVAC installation and service technician.

Axial Spacing for Consistent Flare Geometry

The NTF66’s axial spacing system controls the depth and angle of the flare cone with precision on every use — eliminating the guesswork that leads to under-flared or over-flared connections. The result is a repeatable, dimensionally accurate flare that seats correctly and seals reliably every time.

Patented Rivet Connection for Secure Operation

The patented rivet connection design locks the flaring cone securely in place during the flaring process, preventing movement and ensuring consistent contact between the cone and the tube end. This precision engineering is what sets the NTF66 apart from standard flaring tools.

Nitride Treatment for Enhanced Durability

The NTF66 has undergone nitride surface treatment — a hardening process that significantly increases surface hardness and wear resistance compared to untreated steel. This makes the NTF66 more robust and longer-lasting, maintaining its precision flaring performance over years of professional use.

Six Tubing Sizes Covered

The NTF66 handles tubing OD sizes of 1/4″, 5/16″, 3/8″, 1/2″, 5/8″, and 3/4″ — covering the full range of copper tube sizes commonly used in residential and light commercial HVAC and refrigeration work. One tool handles every size you’ll encounter on the job.

Built for Daily Professional Use

Ergonomic, precise, and built to last, the NTF66 is designed for technicians who flare tube daily and can’t afford inconsistent results. When the quality of your flare determines the quality of your installation, the NTF66 gives you the confidence to work efficiently and accurately.
