Yes. Pressure or leak testing is strongly recommended, especially for gas and critical systems.

Yes. No curing time is required.

No. PTFE tape is a standalone mechanical sealing material.

Usually 3–8 wraps depending on pipe size, tape density, and application conditions.

Threads must be clean. Wrap in the tightening direction starting from the second thread with consistent tension.

Yes. Installation guides, videos, and application instructions are available.

No. It is recommended to replace the tape after disassembly to ensure sealing reliability.

Check product selection, wrapping method, and thread condition. Reinstallation or replacement may be required.

Generally no, unless the threaded connection is disassembled and reinstalled.

The plastic spool has a shelf life of approximately one year. The PTFE tape itself has no expiration date under proper storage conditions.

We accept T/T (bank transfer) and sight L/C.

Standard packaging is 10 rolls per blister pack, with customized inner boxes and export cartons depending on product size.

Yes, subject to stock availability and production capacity.

Yes. We support worldwide export and region-compliant logistics solutions.

Yes. Phased shipment options are available for project-based orders.

Yes. Annual supply agreements and stable supply chain support are available.

Yes. We support customization of size, density, color, packaging, and private branding.

For regular orders, it takes 35-40 days after receiving the deposit. For project-based orders, confirmation will be based on production schedule and specifications.

MOQ depends on product series. Standard MOQ is typically 20,000 rolls per item, with flexibility for project-based and long-term cooperation orders.

Yes. Certification reports including UL, DVGW, and WRAS are available.

Yes. We support EPC projects, bulk procurement, and long-term supply agreements.

Yes. Equivalent replacement solutions are available, subject to validation under actual operating conditions.

Yes. Samples are available for field testing, system validation, and performance evaluation.

Yes. Different product series comply with standards such as UL, DVGW, WRAS, and AGA depending on application requirements.

Yes. We provide certifications, technical specifications, and testing documentation for EPC bidding and project approval.

Yes. PTFE offers excellent resistance to most chemicals, though compatibility should be verified for strong oxidizers.

The standard operating temperature range is −190°C to +260°C (−310°F to +500°F). Performance may degrade beyond this range.

Leakage is usually caused by incorrect product selection, improper installation, or insufficient tape density.

Standard-density tape may deform under pressure, increasing delayed leakage risks in critical systems.

PTFE tape is easier to install and removable, while liquid sealants are better for permanent sealing applications.

Yellow is the industry-recognized color for gas applications, improving safety identification on-site.

High-density tape offers better creep resistance, sealing stability, and longer service life.

GasSafe is for gas systems, Aqua for water systems, ChemGuard for chemical applications, and UltraGas for oxygen and high-purity gas systems.

Yes. We assist with product selection, system compatibility analysis, and troubleshooting support.

Product selection should always match media, pressure, temperature, and certification requirements. Incorrect selection may lead to delayed leakage rather than immediate failure.

Yes. Technical specifications, material data, test reports, and engineering recommendations are available for design evaluation and system assessment.

Yes. Different product series vary in density, creep resistance, cold flow performance, and certification systems such as UL, DVGW, and WRAS.

Yes. We provide application-based selection guidance and recommend suitable product series for gas, water, chemical, oxygen, and industrial systems.

Selection should be based on four key factors: media type (gas, water, chemical, oxygen), pressure level, temperature range, and required certifications such as UL, DVGW, or WRAS. Critical systems should use engineering-grade or high-density tape to avoid delayed leakage risks.

Yes,we have.
