PTFE Straight Compression Fittings

Description

PTFE Straight Compression Fittings

IKSONIC PTFE straight compression fittings are listed for tube connection enquiries, with threaded model designations across M, G, NPT, ZG, PT and R groups. The material named for this range is PTFE (polytetrafluoroethylene). Select the complete model designation, then confirm the connection dimensions and mating component requirements for your assembly.

IKSONIC is a China manufacturer and supplier handling factory and wholesale enquiries for PTFE fittings. The tables below retain 299 listed model entries, grouped by their markings. These entries are selection references, not complete dimensional drawings or confirmation of interchangeability.

Product Overview

Item	Details
Product	PTFE straight compression fittings
Material named	PTFE (polytetrafluoroethylene)
Model groups	M, G, NPT, ZG, PT and R markings, plus male-thread entries without a letter prefix
Selection references	299 listed model entries
Dimensions and units	Retained as listed; confirm the measurement unit and dimensional reference for each connection
Connection specification	Confirm thread requirements, tube dimensions and physical connection arrangement for the selected model

Reading the Model Designations

Model numbers, fractions, parentheses, repeated hyphens and the different φ and Ф characters are retained. Chinese labels are translated or transliterated into English as explained below. Male thread translates the original male-thread label. The term cun is transliterated source nominal pipe-size notation; the connection standard must be confirmed. It is not converted to an equivalent diameter or assigned a measurement standard here.

Do not assume that a diameter-symbol value identifies the tube outside diameter, inside diameter or fitting bore, or that an unlabelled number is in millimetres. Parenthetical values remain part of the designation and are not independently verified conversions. Provide your required dimensions with explicit units.

M, G, NPT, ZG, PT and R markings are reproduced as listed. Confirm the exact thread specification and mating connection for each selected entry. No equivalence between differently marked models, thread series or nominal sizes is asserted here. The designation alone does not establish the complete port arrangement.

Selection and Application Review

Identify the complete fitting designation and the connection required at each position. For tubing, provide the actual outside diameter, inside diameter where relevant, material and measurement units. For threaded connections, provide the required thread specification, nominal size, pitch where applicable, and mating component details. Confirm any installation-space or dimensional constraints before ordering.

Application suitability requires review of the medium, concentration, operating temperature, pressure and installation conditions. This listing does not establish numerical pressure or temperature ratings, chemical compatibility, dimensional tolerances or certification status.

China Factory and Wholesale Enquiries

For a wholesale enquiry, send the complete model designation and quantity for each item. Include your required connection arrangement, dimensions with units and service conditions. If your requirement is not listed, describe the configuration for individual review rather than substituting a similar-looking model.

Contact IKSONIC to discuss PTFE straight compression fittings, factory sourcing and specification requirements. Availability, order requirements and delivery timing need confirmation for the selected items.

Frequently Asked Questions

How do I choose a model?

Start with the complete designation in the relevant table, then confirm the actual tube dimensions, units, threaded connection requirements and fitting arrangement. Matching one number alone is not sufficient to establish compatibility.

Are the φ and Ф values tube outside diameters in millimetres?

The listed notation does not establish that interpretation for every entry. Provide the actual tube outside diameter and unit, and confirm the dimensional reference required for the selected fitting.

Are G, NPT, ZG, PT and R models interchangeable?

Do not select a substitute based on a similar nominal size. These markings are retained separately; the exact thread specification and mating component must be checked for your assembly.

Why do some PT models have two hyphens?

The tables retain the original single-hyphen and double-hyphen entries separately. The extra separator is not used to infer a different construction or port layout. Use the complete designation and confirm the intended configuration.

Do parentheses specify a verified size conversion?

No conversion is asserted by this listing. The parenthetical values are preserved as part of each model designation. Confirm the actual dimensions and units for the component you need.

Can I enquire about a non-listed configuration or wholesale quantities?

Yes. Provide the required connection details, dimensions with units, quantity and application conditions. Non-listed configurations require individual review.
