EZ-FLO® Style 206

Expansion joints for general service applications

Garlock’s Style 206 EZ-FLO® Expansion Joint with an ABRA-SHIELD® tube is the only offering specifically engineered for abrasive high-temperature media. This unique, proprietary material provides 50% better abrasion resistance than standard materials, and lasts up to 3 times longer than traditional EPDM and gum rubber expansion joints.

Remains unphased after long-term exposure to high-heat and aggressive media, providing long-lasting protection in extreme applications where safety is a concern.

Style 206 spool-type non-metallic piping expansion joints are manufactured with Garlock’s self-flushing flowing arch design, eliminating the media build up responsible for premature failure in other wide arch designs.

This proprietary construction reduces fluid turbulence, often the culprit of catastrophic piping and equipment failure. Garlock style 206 is intended for use in dynamic, high-pressure applications where low spring rates and higher movements are a requirement.

ABRA-SHIELD® is Garlock’s proprietary urethane elastomer designed to reduce wear and extend service life. This unique material was developed for extreme temperatures and highly abrasive applications typically found in the power generation, fertilizer, mining, chemical, oil and gas industries. In many cases, this material eliminates flow liners and associated gaskets, creating an easier, more cost-effective solution.

Style 206 is available in the following cover material options to protect the exterior of your expansion joint: Chlorobutyl for general service, EPDM and Fluoroelastomer for UV, ozone, water impermeability and temperatures up to 300°F. Neoprene is an excellent choice for marine use, while utility grade Nitrile is perfect for oily environments.
For added durability, all Garlock expansion joints are painted with a proprietary blue protective coating.

  • Self-flushing design eliminates media buildup and reduces fluid turbulence
  • High pressure resistance ensures longer life and reduces inventory requirements

ADDITIONAL INFORMATION

Standard Design

  • Tube — Standard chlorobutyl liner extends to outer edge of the flange for excellent chemical resistance. The flowing arch design adds pressure resistance and reduces product buildup. Seamless tube creates a positive flange seal without gaskets.
  • Body — Rubber impregnated tire cord and polyester cross-wrapped in bias-ply construction.
  • Cover — Homogeneous layer of chlorobutyl elastomer extends to the outside edge of the flange. Coated with a weather-resistant protectant.

Optional Configurations

  • Custom drilling: ANSI, DIN, AWWA, BS, JIS, and special drilling patterns available on request
  • Extended Face-to-Face (pressure/vacuum ratings may be affected)
  • Accomodate misalignment: lateral, angular, and torsional offsets
