SealTight

IDEX SealTight Fingertight Fittings

IDEX SealTight Fingertight fittings are engineered for ultra-secure, high-pressure connections in demanding LC and UHPLC applications. Designed to connect 1/16" OD tubing to 10-32 coned ports, these fittings deliver exceptional sealing performance without the need for tools.

  • Rated up to 9,000 PSI (620 bar) for extreme pressure workflows
  • Dual-compression design creates two independent sealing zones
  • Slotted ferrule end forms a secondary compression point for added security
  • Fingertight installation eliminates wrenches and reduces port damage
  • Ideal for UHPLC systems where leak prevention is critical

The patented dual-compression SealTight system features a slotted ferrule tip that creates a second sealing interface inside the port. This design dramatically improves leak resistance while minimizing tubing deformation—making it a trusted solution for high-pressure analytical separations.

Chrom Tech is an authorized distributor of IDEX fluidic components and stocks SealTight Fingertight fittings for fast shipping and expert technical support.

Key Definitions â–¸
SealTight Technology
A patented dual-compression sealing system that creates two independent seal points inside the port, improving leak resistance at ultra-high pressures.
Dual-Compression Design
A sealing mechanism where both the ferrule body and the slotted tip compress, forming two sealing zones for added security.
Slotted Ferrule Tip
A precision-cut ferrule end that flexes during tightening to create a secondary compression seal inside the port.
10-32 Coned Port
A standard chromatography port geometry designed for fingertight fittings and high-pressure applications.
Fingertight Fitting
A fitting designed to be installed by hand without tools while maintaining consistent sealing performance.
UHPLC Compatibility
The ability to perform reliably at extremely high pressures common in ultra-high-performance liquid chromatography systems.
Frequently Asked Questions â–¸
What makes SealTight fittings different from standard fingertight fittings?
SealTight fittings use a dual-compression design that forms two sealing points inside the port, helping deliver stronger leak resistance in high-pressure LC and UHPLC connections.
Do SealTight fittings require tools to install?
No. They are designed for fingertight installation to reduce the need for wrenches and help prevent damage from overtightening.
What tubing and port types are SealTight fittings designed for?
These fittings are commonly used with 1/16" OD tubing and 10-32 coned ports. Some SealTight ferrules also fit M6 coned configurations depending on the part.
Are SealTight fittings suitable for UHPLC pressures?
Yes. SealTight fittings are commonly specified for high-pressure workflows and are often used in UHPLC connections where leak prevention is critical.
Can I reuse SealTight fittings and ferrules?
In many cases, yes. For best results, inspect ferrules for deformation or wear and replace the ferrule if you see leaks or reduced sealing performance.
