Plugs designed for HVAC duct and chimney blocking operations
Pipemade’s FlexPlugs are pressure operated plugs designed for HVAC duct and chimney blocking operations when you need to restrict a part of the duct system for cleaning purposes, or for example when you need to block one side of a branch connection.
These plugs are designed for temporary plugging & flow restriction, not to be used for extended amounts of time under pressure.
Use Temperature: Min. -10°C to max. +60°C
Manufactured in Finland from high quality, hi-flex PVC.

In order to inflate the plug we suggest you utilize a common manual pump or a battery operated tire inflator. The FlexPlug must always be inflated SLOWLY.
Do not exceed the maximum inflating pressure. If you inflate the FlexPlug with a compressor, it is necessary to use a pressure regulator to control the inflation pressure. The inflating device / pump / compressor must always have a pressure gauge for controlling the pressure used to inflate the FlexPlug.
NEVER inflate the FlexPlug into the maximum inflation pressure (1,5 bar) if it is not inside a pipe/duct or other supporting structure. The FlexPlug may overstretch or get damaged if it’s inflated in a free space and left pressurized.
Store these products in normal ambient room temperature, covered from direct UV / sun light.
FlexPlugs are equipped with a 1-year warranty against material and manufacturing errors/flaws, starting from the date of purchase.
