Can it replace seals in rotary equipment?

Yes, when the profile is designed for rotary motion and the operating speed, pressure and lubrication are suitable.

Can TYS help identify the cause of seal failure?

We can evaluate application information, groove dimensions and failure symptoms to help select a more suitable sealing structure.

What information should I provide?

Please provide dimensions, current material, pressure, temperature, medium, motion type and failure condition.

Key features

Alternative to Conventional Elastomer Seals Suitable for demanding applications where conventional rubber seals may face limitations from temperature, chemicals, friction or long-term deformation.

Spring Assisted Sealing The internal metal spring continuously energizes the PTFE sealing lip to maintain stable contact.

Reduced Dependence on Elastomer Elasticity Sealing force is supported by the spring instead of relying only on rubber compression.

Low Friction PTFE Surface Helps reduce sticking, breakaway resistance and dynamic wear.

Suitable for Difficult Media PTFE offers broad compatibility with many aggressive chemicals, gases and industrial fluids.

Custom Replacement Engineering Seal geometry can be designed according to the existing groove, working conditions and failure mode.

AI-Powered supplier vetting

SummaryThe supplier is identified as a trade company associated with manufacturing companies producing composite-material components and metal floating seals. It holds an ISO9001:2015 certificate, maintains documented corrective-action and complaint-handling procedures, and reports in-stock capability, defined inspection instructions, seven quality inspectors, ERP-based operational management, and flexible customization. However, the records show no quality assurance in quality-control processes, no valid manufacturing-capacity contract with an affiliated subcontractor, no overseas warehouse, showroom, agent, or branch, and zero countries listed for overseas services. Innovation evidence is limited: no new products were developed in the past year and no SDK is available, although ODM and OEM services are offered. The supplier has participated in Shanghai PTC 2023 and states OEM service for well-known brands, but no specific customer names or verifiable case details are provided.

CertificationsThe supplier holds an ISO9001:2015 certificate, providing explicit evidence of a certified supplier management system.

After-Sales capabilityDocumented and followed procedures exist for corrective and preventive actions and customer complaints. The supplier also reports in-stock capability and defined service procedures, but lacks overseas warehouses, showrooms, agents, and branches, with zero countries listed for overseas services.

Production capacityAssociated manufacturing operations cover composite products, floating seals, machining, pressing, drying, vulcanization, CNC, and injection facilities. The supplier reports inventory capability, seven quality inspectors, random finished-product inspection, ERP integration, and export sales of 41%–50%, but no valid manufacturing-capacity contract is recorded and quality assurance in quality-control processes is explicitly marked absent.

Customization capabilityThe supplier explicitly provides flexible customization and ODM services, and also reports OEM service for well-known brands. These statements support a positive assessment of customization capability.

Product Q&A

Q:Can a spring energized PTFE seal replace an O-ring?

In some demanding applications, yes. The final suitability depends on groove design, pressure, temperature, media and motion conditions.

Q:Why would an O-ring fail while a PTFE spring seal works better?

O-ring performance can be affected by temperature, chemical attack, swelling, compression set or friction. A spring energized PTFE seal uses a metal spring to maintain sealing force and a PTFE jacket for low friction and chemical compatibility.

Q:Can you use the existing O-ring groove?

Sometimes the existing groove can be adapted, but the groove dimensions should be reviewed before replacement.

Q:Can the seal be used when rubber swells in chemical media?

PTFE offers broad resistance to many chemicals, but the exact medium must be confirmed before material selection.

Q:Is it suitable for very low friction applications?

Yes. PTFE is commonly selected when low sliding friction is important.
