Valco HPLC Fluidic Connections
Chrom Tech provides a complete line of Valco HPLC fittings and fluidic connections engineered for leak-free, high-pressure performance. These precision-machined stainless-steel components—including unions, tees, crosses, reducers, and adapters—are designed to deliver secure, consistent flow paths in liquid chromatography systems.
Valco fittings use a compression-style ferrule design, ensuring tight, reproducible seals without deformation or flow restrictions. Whether connecting capillary tubing, adapting between thread types, or linking multiple flow paths, Valco hardware offers reliability and chemical compatibility for demanding analytical applications.
From internal unions and reducing connectors to NPT adapters and syringe fittings, Chrom Tech supports laboratories with durable components that help maintain system integrity and chromatographic precision.
Frequently Asked Questions
What makes Valco fittings ideal for HPLC systems?
Valco fittings are manufactured to high precision tolerances, providing excellent sealing, corrosion resistance, and mechanical stability even under high-pressure chromatographic conditions.
How do internal unions differ from reducing unions?
Internal unions connect tubing of the same internal diameter, while reducing unions join tubing of different sizes, allowing seamless transitions in flow paths without introducing dead volume.
Are Valco fittings compatible with other manufacturer systems?
Yes. Valco stainless-steel fittings and adapters follow standard HPLC thread and port dimensions, making them compatible with most major instrument brands and connection types.
