Tees

Valco tees are precision fluidic connectors designed to join three tubing lines of the same outer diameter, creating consistent, low-volume flow paths in chromatography and analytical systems. These tees support reliable signal splitting or flow distribution while maintaining system integrity.

Standard Valco tees are manufactured from 300 series stainless steel for strength and chemical compatibility. Additional material options—including Hastelloy C, gold-plated stainless steel, and titanium—are available for aggressive solvents, inert applications, or specialized operating environments.

Key Definitions â–¶
Tee Fitting
A fluidic connector that joins three tubing lines of the same outer diameter, enabling flow splitting or merging in chromatography systems.
Tubing OD
The outer diameter of tubing. Valco tees are selected based on matching tubing OD to ensure proper compression and sealing.
Flow Distribution
The division or merging of fluid paths through a tee fitting while maintaining consistent system pressure and volume.
300 Series Stainless Steel
A corrosion-resistant stainless steel commonly used in chromatography fittings for strength, durability, and chemical compatibility.
Compression Connection
A sealing method that uses a nut and ferrule to compress onto tubing, creating a leak-resistant interface without permanent tubing deformation.
Material Options
Valco tees are available in 300 series stainless steel, Hastelloy C, gold-plated stainless, and titanium to support aggressive or specialized applications.
Frequently Asked Questions â–¶
What are Valco tees used for?
Valco tees are used to connect three tubing lines of the same outer diameter, allowing flow splitting or merging in chromatography and analytical systems.
Do all three ports on a Valco tee use the same tubing size?
Yes. Standard Valco tees are designed for three lines of the same tubing outer diameter to ensure consistent compression sealing and balanced flow paths.
What materials are available for Valco tees?
Standard tees are manufactured from 300 series stainless steel. Optional materials include Hastelloy C, gold-plated stainless, and titanium for aggressive solvents or specialized applications.
Are Valco tees suitable for HPLC and UHPLC pressures?
Yes. Valco tees are engineered for high-pressure chromatography environments and are commonly used in HPLC and UHPLC systems when properly installed.
Can Valco tees be reused?
The fitting body may be reused, but nuts and ferrules should be inspected for wear. Replacing deformed ferrules is recommended to maintain reliable sealing performance.
