Fingertight Fittings

IDEX Fingertight Fitting Categories

Chrom Tech offers a complete selection of IDEX Fingertight fittings engineered for fast, secure, and tool-free fluidic connections in HPLC, UHPLC, and laboratory flow systems. Designed to reduce downtime and simplify routine maintenance, Fingertight fittings eliminate the need for wrenches while maintaining consistent sealing performance for repeatable, leak-resistant connections.

Key Definitions â–¸
Fingertight Fitting
A fluidic connector designed to be installed securely using only finger pressure—eliminating the need for wrenches or tools while maintaining a leak-resistant seal.
One-Piece Design
A fitting construction where the ferrule is permanently integrated into the nut, allowing fast installation and preventing the ferrule from sticking inside the receiving port.
Two-Piece Design
A fitting configuration using a separate, replaceable ferrule—allowing worn ferrules to be replaced without discarding the nut for improved cost efficiency.
SealTight Technology
A dual-compression sealing system that creates two independent sealing zones to improve pressure tolerance and leak resistance in high-pressure LC applications.
LiteTouch System
A dual-grip ferrule system designed to hold tubing at two compression points while preventing tubing twist during installation—optimized for hard tubing such as stainless steel and PEEK.
Coned Port
A port geometry featuring a tapered internal surface that allows tubing and ferrules to seat securely for high-pressure sealing in chromatographic systems.
Frequently Asked Questions â–¸
What is the difference between one-piece and two-piece Fingertight fittings?
One-piece fittings have an integrated ferrule for quick installation, while two-piece fittings use a separate ferrule that can be replaced independently—making them more economical for high-use systems.
Do I need tools to install Fingertight fittings?
No. Fingertight fittings are designed to be installed securely using only finger pressure, eliminating the need for wrenches or specialty tools.
Which Fingertight fitting is best for high-pressure applications?
SealTight Fingertight fittings are recommended for high-pressure workflows, as their dual compression system provides enhanced leak resistance at pressures up to 9,000 PSI.
Can LiteTouch fittings be used with soft polymer tubing?
No. LiteTouch fittings are designed for hard tubing such as stainless steel and PEEK. Using them with soft tubing may collapse the tubing ID.
How do I choose the correct Fingertight fitting?
Selection depends on tubing OD, port type, pressure requirements, and material compatibility. Chrom Tech specialists can help you select the optimal configuration.
