To select a corrugated R14 wire-braided PTFE hose, confirm the conveyed medium, operating temperature and pressure, hose dimensions, connection type, movement, and installation environment before requesting a quotation. “R14” can be used differently across product catalogs, so buyers should verify the construction and performance data on the supplier’s drawing or datasheet rather than relying on the designation alone. A suitable hose assembly combines a PTFE liner, reinforcement, and end fittings chosen for the actual service conditions. At Hengshui Xinchi Hose Manufacturing Co., Ltd., we recommend sharing these application details early so our team can help clarify the required configuration.

This guide is for procurement teams, engineers, equipment manufacturers, and maintenance buyers comparing corrugated PTFE hose assemblies. It is useful when a project requires chemical compatibility, flexibility, or a hose assembly that can be specified with suitable end connections. It can also help buyers prepare a complete request for quotation (RFQ) and identify questions that need supplier confirmation.
It is not a substitute for a product datasheet, engineering review, or application-specific compatibility check. A hose’s safe operating limits depend on its size, liner construction, braid, fittings, temperature, pressure, and installation. Confirm all limits for the exact assembly you intend to purchase.
A corrugated PTFE hose has a flexible, convoluted PTFE liner rather than a smooth-bore liner. A metal wire braid, commonly stainless steel, reinforces the hose and helps it resist pressure and external mechanical effects. End fittings connect the hose to equipment or piping, so the completed assembly—not just the liner—must match the service requirements.
“R14” is a designation used in some product descriptions, but buyers should confirm what it means in the specific supplier’s catalog. Do not assume that two hoses labeled R14 have identical dimensions, pressure ratings, materials, or qualification requirements. Request a drawing and technical data for the selected size and assembly.
The corrugated profile allows the liner to flex, which can be useful where a rigid pipe would not accommodate movement or routing. PTFE is selected in many applications for its chemical resistance, but compatibility still depends on the specific chemical, concentration, temperature, and exposure conditions. The wire braid reinforces the hose, while the fitting design provides the connection to the system.
These features do not make every corrugated hose suitable for every service. Excessive bending, twisting, vibration, unsupported weight, or operation outside the confirmed limits can shorten service life or create a safety risk. Follow the manufacturer’s installation guidance and inspect the assembly as part of normal maintenance.
Configurations can differ by liner profile and size, braid material and coverage, fitting material, fitting style, and assembly length. Stainless steel grades such as 304 or 316 may be requested for braid or fitting components, but the appropriate grade depends on the environment and product configuration. Ask the supplier to identify each wetted material and external material in the offered assembly.
PTFE has a melting point of approximately 327°C, but this material property is not a hose operating-temperature rating. The usable temperature range of a completed hose assembly may be lower and can vary with pressure, size, fittings, and construction. Use the supplier’s assembly-specific operating limits, not the liner’s material property, to assess suitability.
| Specification | What to confirm |
|---|---|
| Hose size | Inside and outside dimensions, nominal size, and dimensional tolerances |
| Pressure and temperature | Operating and peak conditions, plus applicable limits for the complete assembly |
| Materials | PTFE liner, braid grade, fitting material, and any additional wetted components |
| Connections | Fitting type, size, thread or flange details, orientation, and sealing method |
| Installation | Assembly length, routing, minimum bend guidance, movement, and support requirements |
Start with the medium that will pass through the hose. Provide the chemical name, concentration if known, and whether the hose will see cleaning agents or process fluids during service. Ask the supplier to review compatibility for the actual conditions rather than relying on a general statement that PTFE is chemically resistant.

Next, describe the pressure and temperature profile, including normal operation, startup, shutdown, surges, and cleaning cycles where relevant. State whether the system is pressurized, under vacuum, or exposed to both conditions. A hose that meets one operating condition may not be appropriate for a different peak condition.
Finally, explain how the hose will be installed and used. A static connection has different movement demands from an assembly that flexes during equipment operation. Provide the space available for routing, expected movement, nearby heat sources, exposure to abrasion, and any support or protective sleeve requirements.
A clear RFQ lets suppliers quote the same requirement. For example, a buyer might describe an illustrative assembly length of 1,000 mm and a hypothetical operating pressure of 10 bar, then separately state the actual project values for review. These example figures are not a recommended hose specification or a rating for any R14 product.
Include required quantities, delivery destination, target schedule, packaging needs, and any documentation requested by your organization. If a specification is not yet fixed, identify it as open for supplier review instead of presenting an estimate as a final requirement. This makes it easier to identify technical gaps before commercial terms are compared.
Pricing depends on the selected diameter, liner and braid configuration, assembly length, fittings, materials, quantity, and documentation or packaging needs. Custom end connections or special inspection requirements can also affect the quotation. For an accurate comparison, request pricing against a complete drawing or a shared specification.
Minimum order quantities and lead times vary by configuration, material availability, production planning, and order size. We do not recommend assuming a standard MOQ or delivery period without confirming the current offer. Ask suppliers to state the quoted quantity, production lead time, shipping terms, and the point at which the schedule begins.
Compare suppliers on technical fit as well as price. A low initial price does not establish that the hose is compatible with the medium or suitable for its installation. Resolve differences in construction, test documentation, and commercial terms before selecting a source.
A corrugated R14 wire-braided PTFE hose should be specified as a complete assembly, with its designation, construction, dimensions, materials, fittings, and operating limits confirmed by the supplier. The most important selection inputs are the medium, pressure, temperature, dimensions, connections, and installation conditions. Because nomenclature and ratings can vary, verify them against the exact product documentation instead of inferring performance from “R14.”
To move your project forward, prepare an RFQ with the application details, target dimensions, connection requirements, quantity, and schedule. Hengshui Xinchi Hose Manufacturing Co., Ltd. can review the information and discuss a suitable hose configuration, available customization, and the documentation required for your evaluation. Contact our team with your drawings or specifications to request a product consultation and quotation.
