PFA Connectors
Product Overview
Fluoropolymer fittings for tube connections and OEM fluid assemblies
Yozonetech supplies PFA connectors for joining fluoropolymer tubing in equipment and fluid-handling systems. Choose straight, elbow, tee, threaded, reducing or adaptor configurations to match your tube dimensions and installation. The catalog includes insert-type, flared and welded connection designs, together with sleeves, union nuts, plugs and other components.
Product Advantages
A broad choice of configurations
Review 27 illustrated connector and component groups to define the flow path, connection interfaces and mounting arrangement.
Common inch tube sizes
The common specification table lists 1/8, 1/4, 3/8, 1/2, 3/4 and 1 inch tube-size designations with corresponding millimeter values.
Assembly components included in the range
Specify the connector body, sleeve or insert, union nuts and any required accessories together so the proposed assembly can be reviewed as a complete connection.
Custom specification support
Other specifications can be reviewed. Send a drawing, mating tube dimensions, thread requirements and quantity to confirm the proposed design, price and lead time.
Connection Design Options
| Connection family | Selection focus |
| Insert-type connections | Confirm tube interface, insert or sleeve design, nut and assembly requirements |
| Flared connections | Confirm flare geometry, preparation method and compatible nuts/components |
| Welded connections | Confirm weld-end geometry, mating material and joining procedure |
For chemically demanding or purity-sensitive service, specify the actual medium, temperature, pressure and cleanliness requirements. Material identity alone does not establish the finished assembly’s pressure rating or cleanliness qualification.
Common Sizes and Product Photographs
All five groups in the source common specification table use the same six nominal tube-size pairs below. These are mating tube-size designations, not overall connector dimensions, thread sizes or complete machining dimensions.
| Tube size (inch) | Catalog size (mm) |
| 1/8 | 3.175 |
| 1/4 | 6.35 |
| 3/8 | 9.53 |
| 1/2 | 12.7 |
| 3/4 | 19.05 |
| 1 | 25.4 |
| Catalog type group | Listed size coverage |
| Straight connection | All six inch/mm pairs above |
| Elbow connection | All six inch/mm pairs above |
| Tee connection | All six inch/mm pairs above |
| Male threaded connection | All six inch/mm pairs above |
| Other configurations | All six pairs listed; reducing unions, reducing elbows, reducing male fittings, reducing plugs and other parts require exact interface specifications |
Original catalog product photographs. Custom sizes and other specifications can be reviewed against your drawing.
Connector Designs Straight Elbow and Tee
Cross-section illustrations show the connection arrangements. Specify the exact design and mating tube rather than selecting from appearance alone.
Connector Designs Reducing Mounting and Adaptors
Reducing and adaptor designs require both end sizes and interface details. Panel-mount connections also require the mounting-hole and panel-thickness specification.
Connector Designs Threaded Ends Plugs and Components
Union nuts, sleeves, plugs and other components must match the selected connection family. The source shows two tee-adaptor and two union-elbow-adaptor forms; they remain separate illustrations here.

Applications and Installation Requirements
PFA connectors can be reviewed for chemical equipment, laboratory instruments and industrial fluid assemblies. For semiconductor or other contamination-sensitive systems, specify material grade, all wetted components, surface condition, cleanliness and packaging requirements for the exact product.
Provide normal and maximum temperature, working and peak pressure, fluid composition and any vacuum, pulsation or movement. Confirm the connector and tube ratings together. Request the appropriate assembly instructions and inspection requirements for the chosen connection design.
Frequently Asked Questions About PFA Connectors
1. Which PFA connector should I choose for my application?
Choose a straight union for joining tubing, an elbow for changing direction, a tee for branching, or a reducing connector for connecting different tube sizes. Send us your system layout or drawing so we can help identify the required connectors and simplify your purchasing list.
2. What PFA connector sizes can I order?
The catalog lists six common tube sizes: 1/8, 1/4, 3/8, 1/2, 3/4 and 1 inch, corresponding to 3.175, 6.35, 9.53, 12.7, 19.05 and 25.4 mm. These are nominal mating tube sizes. Include your actual tube OD, ID and tolerances when requesting a quote to confirm compatibility.
3. Can I order connectors for an existing tubing system?
Yes—send the tubing dimensions, connection details and a drawing or clear photographs of the existing fitting. These details help us review a suitable replacement and reduce the risk of ordering incompatible parts. Appearance alone is insufficient to confirm interchangeability.
4. How do I choose between insert-type, flared and welded connections?
The right choice depends on your tubing, assembly process, maintenance needs and operating conditions. Insert-type and flared designs require matching preparation and components; welded designs require compatible weld ends and a defined joining procedure. Share your installation requirements so the connection design can be reviewed before purchase.
5. Are these PFA connectors suitable for corrosive chemical transfer?
PFA connectors are an option for chemically demanding fluid systems, but suitability depends on the chemical, concentration, temperature and complete assembly. Send your process conditions with your inquiry so we can review the proposed connector and all wetted components together.
6. Can I use these connectors in semiconductor or high-purity systems?
For these applications, specify the required material grade, cleanliness, packaging and supporting documentation. Request confirmation for the exact connector before ordering. Defining these requirements early helps align the quotation with your equipment qualification needs.
7. Can I purchase nuts, sleeves and other components with the connectors?
The catalog includes sleeves, union nuts for insert-type and flared connections, plugs and other components. Include these items in your inquiry so the complete connection can be quoted together. Matching components at the purchasing stage helps avoid assembly delays caused by missing or incompatible parts.
8. Can you review custom sizes, reducing connectors or special adaptors?
Yes. Other specifications can be reviewed against your drawing. Provide both end sizes, thread details and any mounting dimensions, together with the required quantity. This allows us to confirm the proposed design, availability, pricing and lead time for your project.
9. What temperature and pressure ratings should I specify?
Provide your normal and maximum temperatures, working and peak pressures, and any vacuum or pulsation conditions. Ratings must be confirmed for the selected connector, tubing and assembled connection. Including these conditions in your inquiry helps us review a configuration that matches your actual service requirements.
10. How can I get an accurate quotation quickly?
Email ptfetube@yozonetech.cn with the connector type or drawing, tube OD and ID, end connections, quantity and operating conditions. Include cleanliness, packaging and documentation requirements, plus your requested delivery date. A complete inquiry helps reduce follow-up questions and makes quotations easier to compare.
