PRODUCT OVERVIEW
Multi-Interface, Multi-Thread Conversion in a Single Product Family
The supplied specification data identifies model names, interface descriptions, pricing fields, and quantities. Material, pressure, temperature, and detailed dimensions are not stated, so they are intentionally not inferred here.
The product range covers 10-32UNF, 1/4-28UNF, 5/16-24UNF, 1/2-20UNF, and M6 interface formats, together with tube-size references such as 1/16, 1/8, and 1/4. This makes interface compatibility the primary selection criterion rather than appearance or price alone.
CHET-10, CHET-11, CHET-17, and CHET-18 are explicitly identified in the source data. Their descriptions include combinations involving 1/4-28, M6, 1/2-20, and 5/16-24 interfaces, supporting straightforward comparison across mixed-thread connections.
CHZH01–CHZH10 are listed as adapter fittings, but the source data does not specify their exact end interfaces. They are therefore presented as a separate CHZH family, with interface details to be confirmed against the applicable product specification, drawing, or technical documentation before purchase.
Where a change in line direction is required, the range includes 1/4-28 flat-bottom and 10-32 coned-bottom L-shaped unions. For kit-based installations, matched options are also available either without fittings or as a 3-piece fitting kit.

INTERFACE STRUCTURE
How to Read Interface & Kit Specifications
When a specification combines tube size, thread, end geometry, and kit information, verify each item independently before ordering.
Current descriptions include 10-32UNF, 1/4-28UNF, 5/16-24UNF, 1/2-20UNF, and M6.
The same thread family may use different end geometries. Do not select by thread designation alone.
Selected specifications also reference 1/16, 1/8, or 1/4 tube sizes, which should be matched to the actual fluid line.
Confirm whether a matching 3-piece fitting kit is required to avoid missing components or duplicate purchases.
SELECTION GUIDE
Recommended Selection Sequence
A practical sequence is: tube size → thread → flat-bottom/coned-bottom → connection direction → required kit contents.
Identify the actual 1/16, 1/8, 1/4, or other tube requirement first.
Determine whether each side uses 10-32, 1/4-28, 5/16-24, 1/2-20, or M6.
Distinguish flat-bottom, coned-bottom, straight, and L-shaped configurations.
Choose between an adapter-only configuration and a matched 3-piece fitting kit where applicable.
APPLICATIONS
Typical Use Scenarios
Connect instrument-side and tubing-side components that use different thread standards.
Support connection combinations where the specification references different tubing sizes.
Use L-shaped unions where the fluid path must turn within a constrained installation space.
Use kit versions when a complete set of compatible connection components is preferred for laboratory assembly.
FAQ
Frequently Asked Questions
What is the difference between a 3-piece fitting kit and a version without fittings?
Selected interface combinations are offered in both forms. If compatible fittings are already available, compare the version without fittings. If you prefer a more complete matched purchase, compare the 3-piece fitting kit.
Can flat-bottom and coned-bottom interfaces be used interchangeably?
The supplied specifications list flat-bottom and coned-bottom variants separately. Treat end geometry as an independent compatibility parameter rather than relying on thread designation alone.
What are the exact interfaces for CHZH01–CHZH10?
The supplied data lists CHZH01 through CHZH10 as adapter fittings but does not provide their two end-interface parameters. Confirm the applicable product specification or technical documentation before purchase.
What if none of the standard options matches my setup?
A custom-size option is included. Provide both interface specifications, tube size, installation direction, dimensional constraints, and required quantity for review.
Why are material, pressure, and temperature ratings not shown?
Those fields are not included in the supplied source data. They are intentionally omitted rather than estimated.
