Teflon® Woven Flange Guards

Porous spray guards can be used around flanges and known potential leak points, causing the material to coalesce back to a liquid and rendering it non-hazardous.

The Spray Guard is manufactured from three layers of woven Teflon® coated fibreglass fabric, with a central Teflon® liner for strength and a 100% TFE draw string and a Velcro fastener. This material is inherently resistant to Ultra-Violet radiation and includes a ‘litmus’ leak indicator patch contained within a clear Teflon window.

When the draw string is tightened the fabric is drawn over the flange bolts to the pipe wall and eliminates lateral spray out and mist formation.

The fluid leak is contained, remains as a liquid and will seep through the Spray Guard to fall as droplets.

The Teflon® Spray-Guard is designed for use on flanges valves, threaded connections, pumps, flow meters & special applications.

The Spray Guard is fully re-useable and is currently used on several UK Offshore installations and within the maritime industry for vessel engine rooms. The Spray Guard is ABS type approved.
