Description
PTFE Hexagonal Blind Pipe Caps
IKSONIC PTFE hexagonal blind pipe caps combine an internal thread, a closed end and an external hexagonal profile. These female-threaded caps are intended for closing compatible male-threaded pipe or fitting connections. The listed material is virgin PTFE (polytetrafluoroethylene), with a white appearance.
Choose from 83 listed thread options across G, NPT, PT and metric M series. IKSONIC is a China manufacturer and supplier for wholesale PTFE component enquiries. For factory sourcing, confirm the exact thread designation, required quantity and application conditions rather than selecting a cap by appearance alone.

Heat and Corrosion Resistance: Confirm the Application
This PTFE cap range is offered for applications where resistance to high and low temperatures and corrosion is a material-selection requirement. Suitability must be reviewed for the actual medium, concentration, operating temperature, pressure and installation conditions. No numerical temperature limit, pressure rating or universal chemical-compatibility claim is specified for this listing.
A matching nominal size alone is not enough to confirm a connection. Verify the thread series and pitch where applicable, the mating component, available thread engagement and the appropriate sealing method. Confirm any required dimensions or tolerances that are not listed in the tables before ordering.
Wholesale and Custom Enquiries
For a wholesale enquiry, provide the exact thread designation and quantity for each size. Include the mating connection, required cap dimensions and intended operating conditions. If you need a non-listed specification, describe it clearly so the factory can review the custom requirement. Contact IKSONIC to discuss PTFE hexagonal blind pipe caps and confirm the configuration for your application.
Frequently Asked Questions
Are these caps female-threaded or male-threaded?
They are female-threaded pipe caps with an internal thread and an external hexagonal profile. The hexagonal exterior is not an external thread.
Which thread options are listed?
The range lists 12 G options, nine NPT options, nine PT options and 53 metric M options, for 83 thread designations in total. The complete selection is shown in the tables above.
Are PT, RC and ZG automatically equivalent?
No interchangeability should be assumed from the markings alone. The PT options also carry RC and ZG markings; confirm the applicable thread specification and mating connection before selection.
Does a DN reference give the cap’s actual dimensions?
No. The DN references shown beside some G options are nominal references. They do not establish the cap’s bore, hexagon size, overall height or thread depth. Confirm the dimensions needed for your assembly separately.
What temperature or pressure rating applies?
No numerical operating rating is stated here. Heat resistance and corrosion resistance must be assessed against the actual service conditions. Request application-specific confirmation before use.
Can I enquire about custom sizes or wholesale quantities?
Yes. Provide the required thread designation, dimensions, quantity and application details. Non-listed configurations and any documentation requirements need confirmation for the individual enquiry.
