Flare-Thru PTFE Hose Assemblies – Full-Flow Chemical Hose Solutions

Custom-manufactured PTFE hose assemblies engineered for maximum chemical resistance, smooth bore integrity, and reliable performance across demanding industries.

WHAT IS FLARE-THRU PTFE HOSE?

Flare-Thru PTFE hose assemblies are engineered so that the PTFE liner extends through the fitting or flange sealing face, creating a continuous, smooth internal flow path. This design ensures the liner — not metal — is the only wetted surface inside the hose assembly, enhancing chemical compatibility and cleanability while reducing contamination issues.
This smooth bore integrity benefits:

  • Process engineers optimizing fluid handling performance
  • Maintenance teams seeking fewer operational issues
  • Buyers & distributors looking for high-performance, specification-ready assemblies

WHY FLARE-THRU DESIGN MATTERS

Standard PTFE Assemblies
In many hose assemblies, the liner stops short of the fitting, exposing metal surfaces to the fluid pathway. Over time, this can lead to media entrapment, corrosion points, or difficulty achieving sanitary cleaning — especially with aggressive chemicals or high-purity fluids.

Flare-Thru Advantage
With flare-thru construction, the PTFE liner:

✔ Extends through the end connection face
✔ Maintains a smooth, uninterrupted bore
✔ Eliminates exposed metal in contact with media
✔ Reduces product buildup and dead zones

This delivers a more robust and reliable assembly for critical process conditions.

PRODUCT FEATURES & OPTIONS

Construction Overview
Liner: Smooth bore PTFE designed to be the only wetted internal surface for optimal chemical compatibility and flow performance.
Reinforcement Options: We offer multiple braid and cover materials to match application needs:

  • 304 stainless steel braid
  • 316 stainless steel braid
  • Polypropylene braid
  • Kynar® braid
  • Silicone outer covers
  • EPDM outer covers

These options balance chemical resistance, abrasion protection, and visual identification for plant environments.

End Connection Types:

  • Flanged (ANSI/ASME and custom patterns)
  • Threaded (NPT, BSP, etc.)
  • Sanitary clamp connections
  • Custom engineered configurations

All assemblies are built to specification and quality-inspected prior to shipping.

Key Benefits

  • Smooth, continuous internal bore – no exposed metal results in reduced contamination and easier cleaning.
  • Custom assemblies built to order – lengths, fittings, and materials tailored to your system.
  • Multiple braid and cover choices – to meet physical protection and identification needs.
  • Enhanced chemical compatibility – PTFE stands up to aggressive acids, solvents, and high temperatures.
  • High-purity suitability – ideal for pharmaceutical, food & beverage, and biotech environments.
