10-32 Coned Port
Appears in CHCQ-01, CHCQ-02, CHCQ-04, CHCQ-05, CHCQ-06 and CHCQ-07. Confirm that the mating component uses the same 10-32 coned interface format.
SCIENTIFIC FLUIDIC CONNECTION · CHCQ / CHSH
CHCQ Interface Adapters / CHSH Lock Rings
A compact selection family for laboratory fluidic connections and interface transitions. The range includes seven CHCQ adapter models covering combinations of 10-32 coned ports, 1/4-28 flat-bottom ports and Luer fittings, together with two CHSH lock-ring models for 3/8-24 and 5/16-24 thread specifications. Selection is organized around the interface at each end, the transition type and the exact model code.

PRODUCT OVERVIEW
Interface Conversion and Locking Components for Research Fluidics
Choose the model by matching the actual interface on the instrument side and the required interface or lock-ring thread on the connected component. Exact model identification remains important even when two items share the same nominal interface description.
The CHCQ series is differentiated primarily by the connection format at each end. Available combinations include 10-32 coned port to 10-32 coned port, 10-32 coned port to 1/4-28 flat-bottom port, 1/4-28 flat-bottom port to 1/4-28 flat-bottom port, 10-32 coned port to Luer fitting, and 1/4-28 flat-bottom port to 10-32 coned port.
For reliable model selection, identify the instrument-side interface first, then confirm the required downstream interface and transition direction. This approach helps avoid choosing by appearance or model number alone when multiple fittings have similar external forms.
The CHSH series covers lock-ring specifications rather than interface adapters. CHSH-01 is identified by a 3/8-24 thread specification, while CHSH-02 uses 5/16-24. These models should be selected according to the mating lock-ring thread requirement.
CHCQ-01, CHCQ-06 and CHCQ-07 all carry the same nominal description of 10-32 coned port to 10-32 coned port. Because their detailed geometry is not differentiated by the current catalog fields, retain the complete model code in purchasing records and confirm the drawing, existing part or technical reference when interchangeability is critical.
For applications where material, pressure rating, temperature range, sealing details or dimensional limits are important, request technical confirmation before ordering. This keeps model selection tied to the complete fluidic assembly rather than interface naming alone.

INTERFACE STRUCTURE
Interface and Structure Guide
Use these descriptions to interpret model naming and narrow the interface family. Final dimensional compatibility should be confirmed from the mating component or technical drawing.
1/4-28 Flat-Bottom Port
Used by CHCQ-02, CHCQ-03 and CHCQ-05. It can form either a same-interface arrangement or a transition to a 10-32 coned interface.
Luer Transition
CHCQ-04 combines a 10-32 coned port with a Luer fitting for applications that require a transition between these two connection formats.
CHSH Lock Rings
CHSH-01 uses a 3/8-24 thread designation and CHSH-02 uses 5/16-24. Select the lock ring by the required mating thread specification.
SELECTION GUIDE
Recommended Selection Sequence
A practical selection sequence is: instrument-side interface → opposite interface or lock-ring thread → structure type → exact model code.
Identify the First Interface
Confirm whether the connection uses a 10-32 coned port, 1/4-28 flat-bottom port or a lock-ring thread.
Identify the Opposite Side
Determine whether the assembly needs the same interface, a mixed-interface adapter, a Luer transition or a lock ring.
Match the Model
Use the selector above to narrow the list, then retain the complete CHCQ or CHSH model code for ordering.
Confirm Critical Parameters
For material, pressure, temperature, sealing or dimensional constraints, request technical confirmation before purchase.
FAQ
Frequently Asked Questions
What is the difference between CHCQ-02 and CHCQ-05?
Both connect a 10-32 coned port and a 1/4-28 flat-bottom port, but the interface order is reversed in their model descriptions. If installation direction matters, confirm which side of the assembly requires each interface.
How should CHCQ-01, CHCQ-06 and CHCQ-07 be distinguished?
All three are identified as 10-32 coned port to 10-32 coned port. Their detailed dimensional or structural differences are not defined by the current catalog fields, so use the exact model code and confirm the drawing, existing part or technical reference when replacement compatibility is critical.
How do I choose between CHSH-01 and CHSH-02?
Choose by lock-ring thread: CHSH-01 is 3/8-24 and CHSH-02 is 5/16-24.
Where can I confirm pressure, temperature, material or dimensions?
These parameters should be confirmed for the exact model and application before ordering. Contact technical support with the model number, mating interface and operating requirements.
