CHDG Series Fluidic Interface Fittings
The CHDG Series is intended for interface connection and port-matching tasks in laboratory fluidic systems. The current range includes 12 standard models: CHDG-01 is identified as a 10-32UNF conical configuration, while CHDG-02 through CHDG-12 are listed as 1/4-28UNF flat-end configurations. A separate custom-order option is also available. Use the interface, end-structure, and purchase-type filters to narrow the available range.
Two Interface Systems Covering Conical and Flat-End Connection Needs
The supplied data explicitly identifies model names, interface descriptors, pricing, and quantity fields. Material, pressure rating, temperature, through-hole dimensions, and external dimensions are not provided and therefore remain subject to technical confirmation.
CHDG-01In the current specification data,10-32UNF Conical. When a laboratory device uses a 10-32UNF port and requires the conical geometry described in the current data, CHDG-01 should be the first model to verify.
CHDG-02 through CHDG-12are consistently identified in the current data as1/4-28UNF Flat End. These 11 models share the same interface and end-structure descriptors in the current source, so differences in length, outer diameter, internal geometry, or other dimensions cannot be determined from this data alone.
CHDG-02 through CHDG-12 are retained as separate models even though the currently visible parameters are the same. If the exact model number is known, select it directly. If only the interface is known, use the original part photo, equipment drawing, or measured dimensions to distinguish the required model.
The current specification data also includes a“Custom Configuration — Contact Us” purchase option. When standard models do not meet the required interface, envelope, or assembly conditions, provide thread details, dimensional constraints, quantity, and working-fluid information for review.
Selection Highlights
Current model descriptions cover 10-32UNF and 1/4-28UNF, allowing selection to begin with the equipment-side thread.
CHDG-01 is conical, while CHDG-02 through CHDG-12 are currently identified as flat-end models, providing a clear structural distinction.
Even where the currently visible parameters are identical, every CHDG-02 through CHDG-12 model remains listed individually.
When standard models do not meet the requirement, submit the interface, dimensional constraints, quantity, and working-fluid details for custom review.

Interface & Structure Guide
This is the only standard model in the current data explicitly identified as 10-32UNF, and it is also marked as conical.
Eleven models are explicitly identified as 1/4-28UNF, forming the main interface group in the current range.
The conical descriptor appears only for CHDG-01 in the current specification data.
CHDG-02 through CHDG-12 are consistently identified as flat-end structures.
Recommended Selection Sequence
First determine whether the equipment port requires 10-32UNF or 1/4-28UNF.
The current range is primarily divided into conical and 1/4-28UNF flat-end groups.
For CHDG-02 through CHDG-12, use the original model number, part photo, or drawing for further verification.
For non-standard interfaces or special geometry requirements, submit the relevant parameters for further review.
Typical Applications
Select the appropriate CHDG fitting according to the equipment-side thread.
When the original CHDG model is known, match the replacement directly by model number.
Use 10-32UNF conical versus 1/4-28UNF flat-end geometry to distinguish the current product groups.
Interface, geometry, or quantity requirements outside the standard range can be reviewed through the custom-order channel.
FAQ
How many standard CHDG models are currently available?
The current specification data includes CHDG-01 through CHDG-12, for a total of 12 standard models, plus one custom-order option.
Which model is the 10-32UNF conical option?
CHDG-01 is explicitly identified in the current data as the 10-32UNF conical model.
Which models are 1/4-28UNF flat-end?
CHDG-02, 03, 04, 05, 06, 07, 08, 09, 10, 11, and 12 are all identified as 1/4-28UNF flat-end models.
What is the difference between CHDG-02 and CHDG-12?
The supplied specification data only identifies these models as 1/4-28UNF flat-end. It does not provide length, diameter, internal geometry, or other dimensional fields, so their detailed differences cannot be determined from the current source.
Can I filter directly by interface?
Yes. The quick selector can narrow the list by 10-32UNF, 1/4-28UNF, or the custom-order option.
Are custom specifications available?
Yes. The current source includes a dedicated custom-order option. Feasibility should be confirmed based on the required interface, geometry, and quantity.
Why are material, pressure rating, and operating temperature not shown?
These technical fields are not included in the supplied specification data, so the page does not infer or publish unverified values.
Purchase & Technical Support
Standard CHDG models can be selected by interface thread, conical or flat-end structure, and exact model number. If only the interface is known and the exact CHDG-02 through CHDG-12 number cannot be determined, provide the original part photo, interface thread, key external dimensions, and required quantity for further verification.
