Virgin PTFE Single Ferrules – Conical Tube Sealing Rings

Description

Virgin PTFE Single Ferrules for Tube Fittings

These white virgin PTFE single ferrules are conical sealing rings for compatible tube fittings. The tapered ring fits around the tube as one component of the connection. Select the ferrule together with the tubing and matching fitting geometry; a model designation alone is not enough to confirm fit.

IKSONIC is a China manufacturer and supplier of PTFE sealing components. For wholesale enquiries, choose a listed model below and provide the tube outside diameter, its measurement unit, and the dimensions of the mating fitting. Custom-size requirements can also be discussed, subject to technical review.

Product Overview

• Material: Virgin polytetrafluoroethylene (PTFE).
• Color: White.
• Form: Single ferrule with a conical outer profile and central tube opening.
• Selection: 37 listed ferrule model designations, reproduced below.
• Supply scope: Ferrule/sealing ring. Tubing, nuts and complete fittings shown in application photographs are not included unless separately specified in the quotation.

Complete Ferrule Model List

The table retains the original model notation and every stated numeric value, including parenthetical values. These are ordering references, not a dimensioned drawing. No unspecified unit or inside/outside diameter has been assigned to a model number. Confirm the measurement units, tube outside diameter and mating dimensions before ordering; parenthetical figures have not been converted or rounded.

Applications and Selection

These ferrules can be considered for compatible tube connections in fluid-handling equipment, gas-line assemblies and chemical-process tubing. Suitability must be assessed for the actual medium, service conditions, tubing material and fitting design. The application photographs show how a ferrule is positioned on a tube; they do not establish a pressure rating, temperature limit or compatibility with every fitting system.

For a replacement, compare the existing ferrule profile and the mating seat rather than relying only on a nominal model label. Provide the required bore, overall height, conical profile and mating dimensions, with units and tolerances, where available. Do not substitute a ferrule based only on visual similarity.

Wholesale and Custom-Size Enquiries

To request a quotation from IKSONIC, include:

• The listed ferrule model and required quantity.
• The actual tube outside diameter and whether the measurement is in millimeters or inches.
• The tube material, fitting type and relevant mating dimensions, all with units.
• Any required tolerances or custom dimensions, supported by a drawing or measured sample details.
• The service medium and operating conditions needed for a suitability review.

Contact IKSONIC to confirm the specification and scope of supply for your enquiry. Pricing and any custom-size feasibility should be confirmed for the requested configuration.

Frequently Asked Questions

Is this a complete tube fitting?

No. This listing is for the PTFE single ferrule/sealing ring. Tubes, nuts and complete connectors visible in the application photographs are examples of use, not an included assembly unless separately specified.

What material and shape are supplied?

The product is a white virgin PTFE ferrule with a conical outer profile. The exact dimensions must be confirmed for the model being ordered.

Does a model number specify an inside or outside diameter?

Not by itself. The source model labels do not define which physical dimension each figure represents. Confirm the tube outside diameter, units and fitting dimensions with your enquiry. Values such as 1.587 and 4.7625 are kept exactly as listed and are not rounded or treated as a separate dimensional specification.

Can I request a model not shown in the table?

You can submit custom-size requirements for review. Include a drawing or measured dimensions, tolerances, quantity and application details. Feasibility and the final specification need to be confirmed before an order is placed.

What pressure or temperature rating should I use?

No numerical pressure or temperature rating is specified here. A material description is not a rating for the assembled connection. Confirm suitability for your medium and operating conditions, together with the tubing and mating fitting, before use.
