The PTFE shield is manufactured from three layers of woven Teflon coated fibreglass fabric with a central Teflon scrim for strength. This material is inherently resistant to Ultra-Violet radiation.
There is a litmus leak indicator patch contained within a clear Teflon window.
The easy to fit, lock tight, fastening system comprises a Velcro strip coupled with a braided 100% Teflon coated fibreglass draw string. When tightened the fabric is drawn over the flange bolts toward the pipe wall thus eliminating a lateral spray out.
The design enables leaks to be released without danger, avoiding pressure-build up within the shield.
The PTFE shield design allows easy installation and removal with no special tools. It can be re-used, even in the event of a leak, thus providing a long term solution.
