Y Pieces

Y Pieces

Glass Y Pieces are pipeline fittings designed to split or combine fluid flow at an angle, typically around 45°, offering smoother flow characteristics compared to standard tees. This angled configuration minimizes turbulence, pressure drop, and mechanical stress, making Y pieces ideal for sensitive chemical, pharmaceutical, and vacuum applications.

Manufactured from borosilicate glass 3.3, Y pieces provide exceptional chemical resistance, thermal stability, and full transparency for real-time visual inspection of flow behavior, bubbles, or color changes.
