PEEK One-Piece Fluidic Fittings
The CHZT Series is a family of PEEK one-piece fluidic fittings developed for analytical instruments, precision laboratory fluidics, compact reaction systems and research equipment. The range includes round-head, flat-head, extended-thread, radius-knurled and external-hex tapered configurations, together with custom distribution structures. Selection can be organized around available installation space, operating method, equipment interface and required flow-path layout.
One-Piece Connection Options for Precision Research Fluidics
CHZT Series PEEK fittings are intended for compact fluidic connections in laboratory instruments, analytical equipment, small reaction platforms and modular research systems. The one-piece format simplifies component identification and installation, which is useful in experimental setups that are frequently assembled, adjusted or reconfigured.
Different models are distinguished primarily by head geometry and installation method. Large round heads provide a larger manual operating surface; small round and flat heads suit restricted spaces; knurled heads improve manual grip; and external-hex tapered versions support tool-assisted installation where access permits.
CHZT-1604 uses an extended-thread design for positions requiring greater effective thread engagement or installation depth. CHZT-1610 and CHZT-1611 both use external-hex tapered geometries, but their exact interface and dimensional differences should be confirmed against the required specification before ordering.
For multi-outlet distribution, special interfaces, non-standard thread length or instrument-specific integration, custom configurations can be discussed using interface dimensions, drawings, available envelope and flow-path requirements.
Design Features
Round, flat, knurled and external-hex forms provide options for different installation clearances and operating methods.
A clear, integrated structure helps simplify identification and installation in experimental fluidic assemblies.
Designed for research systems where a non-metallic engineering-polymer fitting is preferred. System compatibility should be confirmed for the actual medium and operating conditions.
Special interfaces, distribution counts, thread lengths and external geometry can be reviewed for instrument-specific requirements.

Interface & Selection Checklist
Verify tubing outside diameter, tubing material and connection position before selecting a fitting.
Different instruments and fluidic modules may use different threads and interface forms; verify the exact port specification before ordering.
Small round or flat heads are useful in compact spaces; external-hex tapered designs are relevant where tool-assisted installation is required.
If a standard fitting cannot reach the required engagement depth, review the CHZT-1604 extended-thread configuration.
Round and knurled heads are suited to frequent manual handling, while external-hex versions support tool access.
For multi-port distribution, special threads, unusual heads or equipment-specific structures, provide a drawing or dimensional information.
Typical Applications
Connections within or around liquid-transfer paths and tubing modules in analytical instruments.
Connections among tubing, valves and fluidic modules in research experiments.
Inlet, outlet and auxiliary fluidic connections around small laboratory reaction devices.
Experimental platforms that require repeated disassembly, reassembly and flow-path adjustment.
Custom distribution structures can route one inlet toward multiple downstream flow paths.
Custom connection structures can be reviewed against instrument, fixture or experimental-device interfaces.
Installation & Use Guide
Confirm that the fitting model, equipment port and connected tubing match before installation.
Inspect ports and tubing connection areas to keep particles, dust and debris out of the flow path.
Keep the fitting aligned with the interface during engagement and avoid forcing an angled thread start.
For tool-assisted installation, follow the requirements of the actual interface and avoid unnecessary over-tightening.
After installation, inspect the connection and flow path under the intended experimental conditions.
For non-standard fittings, finalize drawings, interface dimensions and quantities before fabrication.
Frequently Asked Questions
What is the main difference between CHZT-1602 and CHZT-1603?
Both are one-piece round-head fittings. CHZT-1602 uses a larger round head, while CHZT-1603 uses a smaller round head. Final selection should also consider the equipment interface and available installation space.
Why are CHZT-1610 and CHZT-1611 both described as external-hex tapered fittings?
Both models belong to the same geometry family but represent different specifications. Exact dimensional and interface differences should be confirmed for the required model before ordering.
Which models should I consider for a compact installation?
CHZT-1603 small round-head and CHZT-1605 flat-head configurations are useful starting points, while the actual interface and surrounding clearance still need to be verified.
Which structures are convenient for frequent manual disassembly?
Round-head and knurled geometries are generally easier to handle manually. CHZT-1602, CHZT-1603 and CHZT-1606 are useful models to compare when operating space permits.
Can special thread lengths or special interfaces be supplied?
Custom configurations can be reviewed. Please provide interface dimensions, tubing specification, thread information, envelope limitations or a structure drawing.
Can multi-outlet distribution structures be customized?
A 1-in / 6-out custom configuration is included in the current range. Other inlet/outlet arrangements can be discussed based on the required experimental flow path.
What information should I provide if I do not know the model?
Provide the equipment model, existing fitting photo, port photo, tubing outside diameter and installation-area photo whenever available. This helps narrow the model and interface requirements.
