PEEK Flangeless Fittings
Designed for laboratory fluidics, chromatography, and microfluidic tubing connections, this PEEK flangeless fitting family covers tubing ODs from 1/32″ and 1/16″ through 2.0–4.0 mm, 1/8″, and 3/16″. Three thread families—10-32, 1/4-28, and 5/16-24—support straightforward selection by tubing size, thread, ferrule/sleeve configuration, and documented pressure rating.

Applications
Designed for serviceable tubing connections across research fluidic systems, with selection based on interface requirements rather than a single application category.
Chromatography & LC Fluidics
For internal or external small-bore tubing connections where serviceability and component replacement are important.
Microfluidic & Reaction Systems
Supports compact connections between microreactors, pump/valve modules, and small-scale fluid transport components.
Custom Laboratory Fluidics
Standardize selection by tubing OD and thread to reduce assembly errors caused by mixed fitting specifications.
High-Pressure Research Fluidics
Where pressure capability is critical, prioritize models with documented ratings and verify tubing, port, and assembly conditions for the complete system.
Installation & Use Guide
Verify tubing OD, thread, port geometry, and ferrule/sleeve configuration together. Do not substitute a visually similar model without confirming the full interface.
Confirm Tubing OD
Use the actual tubing OD as the first selection criterion and avoid mixing imperial and metric tubing specifications.
Verify Thread
Confirm 10-32UNF, 1/4-28UNF, or 5/16-24UNF and verify whether a flat-bottom port is required.
Match Ferrule / Sleeve
For CHFTJ models, verify both the CHRH ferrule and the corresponding CHRT stainless-steel sleeve.
Verify Pressure Rating
Final pressure capability depends on tubing, mating port, and assembly conditions. Contact technical support for models without a documented rating.
Frequently Asked Questions
Quick guidance for distinguishing similar models, interface differences, and documented specification values.
What are the main differences between CHFT, CHFTJ, and CHFTS?
CHFT is the standard flangeless series, CHFTJ uses 316L stainless-steel sleeves, and CHFTS is intended for higher-pressure configurations. Always verify tubing OD, thread, ferrule system, and pressure requirements together.
Why are there multiple models for 1/16″ tubing?
The same tubing OD may be offered with different threads, inverted or flat-bottom structures, ferrule combinations, or pressure designs, so tubing size alone is not sufficient for selection.
What does “—” mean in the pressure-rating column?
It means no explicit pressure rating is provided for that model in the available product documentation. A value is not inferred from similar models.
Can I match a fitting to an existing valve or manifold?
Yes. Provide tubing OD, equipment-side thread, port geometry, target pressure, and media information to narrow the model range.
Purchase & Technical Support
Standard CHFT, CHFTJ, and CHFTS models can be specified directly by model number. If your fluidic interface is uncertain, send the tubing OD, thread, port orientation, target pressure, and media information for technical confirmation.
