Imperial 375FS 45° Large Size Flaring Tool (1/8″ to 3/4″ O.D.)

Built for demanding HVAC/R and automotive A/C applications, the Imperial 375FS delivers clean, repeatable 45° flares on soft copper, aluminum, and brass tubing ranging from 1/8″ to 3/4″ O.D. Featuring a quick slip-on yoke and a hard chrome-finished swivel cone, this flaring tool significantly reduces the physical effort needed to form a perfect flare. The positive clamping bar securely locks the tube to prevent creep, ensuring square, true flares and reducing the need for leak-related reworks.

Technical Specifications

Note: Specifications confirmed via official Imperial documentation. The maximum supported size for the 375FS is strictly 3/4″ O.D.

Tradie Pro Tip: Always deburr the tube inside and out before flaring, and lightly oil the cone. Aim the tube end to sit flush and square in the positive clamping bar—this proper preparation is what stops split flares and weeping joints upon seating.
