PTFE

PTFE (polytetrafluoroethylene) hose assemblies are engineered for applications requiring nonconductive, smooth-bore fluid conveyance. The PTFE tube material provides chemical resistance across a broad range of industrial fluids, including fuels, lubricants, hydraulic oils, and corrosive media. The 301 stainless steel braided cover adds mechanical protection and pressure containment while maintaining flexibility. These assemblies are rated for a temperature range of -65°F to 450°F, making them suitable for both cryogenic and high-heat environments. The brass flareless JIC (FJIC) end connections offer leak-resistant sealing and compatibility with standard JIC fittings. 3G Electric supplies multiple SKUs of PTFE hose assemblies in varying inner diameters (5/16 in, 3/8 in, 1/2 in) and lengths (12 in as standard), with brass FJIC terminations. Each assembly is nonconductive, which is critical for applications where electrical isolation is required to prevent sparking or galvanic corrosion. The smooth bore design minimizes pressure drop and reduces particle entrapment, supporting clean fluid systems. These hoses are commonly used in fuel delivery, pneumatic controls, chemical transfer, and instrumentation lines. 3G Electric provides datasheets and logistics support for global procurement, enabling engineers and maintenance managers to specify and order PTFE hose assemblies with documented performance parameters.

Common Applications

  • Fuel delivery systems — PTFE hose assemblies (e.g., SKU 1PCP6) for nonconductive transfer of diesel, gasoline, or aviation fuels.
  • Chemical processing — PTFE hose assemblies (e.g., SKU 1PCN9) for corrosive chemical transfer in batch or continuous processes.
  • Pneumatic controls — PTFE hose assemblies (e.g., SKU 1PCN3) for clean, nonconductive air or inert gas lines in instrumentation.
  • Lubrication systems — PTFE hose assemblies (e.g., SKU 1PCP6) for oil or grease delivery in machinery requiring electrical isolation.
  • Cryogenic fluid handling — PTFE hose assemblies (e.g., SKU 1PCN9) for liquid nitrogen or other low-temperature fluids down to -65°F.

Frequently asked questions

Common questions about PTFE from 3G Electric.

What is the maximum operating temperature for PTFE hose assemblies supplied by 3G Electric?

The PTFE hose assemblies, such as SKU 1PCP6, 1PCN9, and 1PCN3, are rated for a temperature range of -65°F to 450°F. This covers both low-temperature and high-temperature industrial processes. The PTFE tube material maintains its integrity across this range, while the 301 stainless steel cover provides thermal stability. Always verify the specific fluid temperature limits and consult the datasheet for derating factors if the application involves rapid thermal cycling.

Are PTFE hose assemblies from 3G Electric electrically conductive?

No, these PTFE hose assemblies are nonconductive. The PTFE tube material is an electrical insulator, and the brass FJIC fittings do not create a continuous conductive path through the hose. This makes them suitable for applications where electrical isolation is required, such as in fuel handling systems or near sensitive electronic equipment. The nonconductive property is verified by the manufacturer and is a key specification for safety in explosive environments.

What end connection types are available on PTFE hose assemblies from 3G Electric?

The PTFE hose assemblies feature brass flareless JIC (FJIC) end connections. For example, SKU 1PCP6 has 3/4 in FJIC x 3/4 in FJIC, SKU 1PCN9 has 9/16 in FJIC x 9/16 in FJIC, and SKU 1PCN3 has 7/16 in FJIC x 9/16 in FJIC. These connections provide a metal-to-metal seal without the need for O-rings, suitable for high-pressure and high-temperature service. The brass material offers corrosion resistance and compatibility with standard JIC fittings.

What is the inner diameter range for PTFE hose assemblies stocked by 3G Electric?

3G Electric stocks PTFE hose assemblies with inner diameters of 5/16 in (SKU 1PCN3), 3/8 in (SKU 1PCN9), and 1/2 in (SKU 1PCP6). These sizes cover common industrial fluid handling requirements. The smooth bore design ensures minimal flow restriction and low pressure drop. For custom sizes or longer lengths, contact 3G Electric for availability and lead times.

Can PTFE hose assemblies be used with hydraulic fluids?

Yes, PTFE hose assemblies are compatible with a wide range of hydraulic fluids, including mineral oils, synthetic esters, and phosphate esters. The PTFE tube provides excellent chemical resistance and does not swell or degrade in contact with most hydraulic fluids. However, verify compatibility with specific fluid additives or extreme pressures. The 301 stainless steel cover provides burst pressure protection, but these assemblies are not rated for dynamic flexing in high-cycle hydraulic systems; they are best suited for static or low-motion applications.

Does 3G Electric supply PTFE products?

Yes — 3G Electric (S) Pte. Ltd. supplies PTFE products. We stock the PTFE catalog and supply genuine factory-original products with full manufacturer warranty and technical support.
