Product List

PTFE hose fittings connect a PTFE-lined hose to equipment or another connection. The fitting body is typically metal; “PTFE” describes the hose liner rather than the fitting body material.

Select the fitting by its hose-end design and assembly method as well as its equipment connection.

Product appearance or thread type alone does not confirm hose compatibility. Before selecting a fitting, verify the hose manufacturer and series, hose ID and OD, smooth-bore or convoluted construction, reinforcement type, fitting assembly method, end connection, material, and operating requirements.

For multi-SKU purchasing, send your existing part numbers, product list, hose specifications, drawings, or samples for review.

PTFE Hose Compatibility Checking

A fitting should be selected as part of a confirmed hose assembly rather than by thread size or appearance alone. PTFE hoses can differ in tube construction, wall thickness, reinforcement, dimensions, conductivity, and assembly requirements. These differences affect the insert, socket, sleeve, and assembly method required.

Provide the following information so the fitting and hose combination can be reviewed before sampling or volume purchasing.

Hose Manufacturer and Series

Provide the existing hose brand, series, specification sheet, or hose-marking photo.

End Connection

Specify the thread standard, size, sealing method, and straight, 45°, or 90° configuration.

Hose Dimensions

Provide the nominal size, actual ID and OD, and any available wall-thickness information.

Fitting Structure

Confirm whether a crimp or field-attachable fitting is required and provide any existing assembly reference.

Hose Construction

Confirm whether the hose has a smooth-bore or convoluted PTFE tube and identify its reinforcement construction.

Operating Conditions

Provide the media, working pressure, temperature range, movement, cleaning process, and applicable technical requirements.

Application

PTFE hose fittings are used in selected industrial fluid-transfer and equipment-connection systems where the hose construction, fitting material, end connection, assembly method, operating media, pressure, and temperature have been confirmed as a compatible combination.

Application suitability should be evaluated for the complete hose assembly. The performance of the PTFE hose tube alone does not determine the pressure, temperature, chemical compatibility, or service life of the finished assembly.

Topa Factory Video

This video presents selected production stages for PTFE hose fitting components, including raw-material preparation, CNC body machining, hose-insert processing, socket or sleeve production, thread machining, sealing-surface finishing, deburring, cleaning, surface treatment, inspection, identification, and packing.

For PTFE hose assemblies, dimensional control is required at both the hose end and the equipment connection. Important inspection points include insert geometry, socket or sleeve dimensions, thread accuracy, sealing surfaces, material, finish, cleanliness, and part-number identification.

Before repeat production, the fitting series, PTFE hose specification, assembly method, approved dimensions, material, finish, inspection requirements, packaging, and SKU identification should be recorded. Send your hose information, existing part numbers, drawings, and required quantities for production review.

Planning a Multi-SKU PTFE Fitting Order?

Send your PTFE hose specifications, fitting part numbers, end connections, material requirements, quantity per item, and delivery plan. Topa can review standard and selected custom configurations for distributor replenishment, hose-assembly supply, and OEM production requirements.

PTFE Fittings Features

Structure

Hose-End Interface

The insert, socket, or sleeve must match the dimensions and construction of the specified PTFE hose. A similar hose size does not by itself confirm assembly compatibility.

Connection End

The equipment end may use JIC, NPT, BSP, metric, ORFS, or another specified connection. Thread size, sealing method, mating component, and key dimensions should be verified together.

Assembly Method

Crimp fittings and field-attachable fittings use different components and assembly procedures. The applicable fitting series, tools, preparation steps, and inspection criteria should be confirmed before assembly.

Complete Assembly Review

Working pressure, temperature, chemical compatibility, movement, and service conditions should be determined for the approved hose-and-fitting combination rather than from the hose or fitting material alone

Material

Aluminum

Aluminum is a lightweight material with excellent corrosion resistance and is easily machined to provide high strength while keeping weight low. Aluminum PTFE fittings are commonly used in low to medium-pressure and temperature applications.

Stainless Steel

Stainless steel is an extremely corrosion-resistant metal that can withstand high temperatures and pressures and is well suited for use in chemically reactive environments. Stainless steel PTFE fittings exhibit excellent durability and stability in long-term use.

Carbon Steel

Carbon steel is a lower cost and high strength material suitable for use in environments subjected to higher pressures. It has poor corrosion resistance and often requires additional surface treatment (such as galvanizing or coating) to increase corrosion resistance.

FAQ

What is PTFE hydraulic fitting?

PTFE hydraulic fitting is a fitting specifically for PTFE hose, also known as Teflon hose

Do smooth-bore and convoluted PTFE hoses use the same fittings?

Do not assume they do. Their construction and dimensions may require different hose-end designs. Confirm the exact hose and fitting combination.

Can PTFE hose fittings be reused?

Permanent crimp or swaged fittings should not be treated as reusable. For a field-attachable design, follow the series-specific instructions for inspection and replacement of components. Replacing a sleeve or olive alone does not establish that the remaining parts are suitable for reuse.

How tight should PTFE fittings be?

Assembly requirements depend on the hose construction and fitting series. Use the applicable manufacturer-approved instructions for hose preparation, component installation, lubrication where permitted, crimp dimensions or tightening requirements, and final inspection. A single tightening value or assembly gap should not be applied to every PTFE fitting design.

How is chemical compatibility confirmed?

Chemical compatibility should be checked for every wetted component, including the PTFE tube, fitting body, reinforcement, seals, and any plating or internal components. The media, concentration, temperature, pressure, cleaning process, and exposure time should be reviewed before approving the assembly.

How are pressure and chemical compatibility confirmed?

Review the complete assembly at the intended temperature and pressure. Chemical compatibility must cover the fluid, its concentration, cleaning conditions, and all wetted materials.

Can you cross-reference existing PTFE fitting part numbers?

Existing supplier part numbers, catalogs, drawings, samples, and product photos can be used as identification references. Final interchangeability should be confirmed by checking the PTFE hose series, hose dimensions, fitting structure, connection end, key dimensions, material, assembly method, and operating requirements.

How to install PTFE fittings？

Installation procedures differ between crimp and field-attachable fittings. Confirm the hose and fitting series, prepare the hose according to the applicable instructions, use the specified components and tooling, follow the approved assembly dimensions or tightening procedure, and inspect the completed assembly before use.

Can different fitting sizes and configurations be included in one order?

Yes. Buyers can submit a multi-SKU list covering different hose sizes, end connections, body configurations, materials, and quantities.

Can I use a standard hydraulic fitting with PTFE hose?

Only if the fitting series is specified for that PTFE hose. Matching nominal size or thread type is not enough. The hose-end geometry, components, and assembly procedure must suit the hose.
