FEATURES:

• No more catastrophic plug failures due to defective gauges or operator errors. If the plug is accidentally over-inflated, the relief valve engages, relieving any excess pressure and preventing plug rupture.

• When the relief valve engages, it relieves the excess pressure in the plug, but does not completely deflate, allowing the plug to stay in use throughout the application. Unlike other manufacturers rupture protection devices cause their plugs to fully deflate, shutting the job down and causing tests to fail or back pressure to be relieved. The LANSAS  RUPTURE PROTECTED Pipe Plugs work without this hassle or mess!

• The  relief valve is recessed mounted to prevent physical damage during transportation and jobsite use.

• The LANSAS®  Rubber Dirt Cover protects the  air relief valve against the harsh work environment. Dirt and debris is kept away from the valve.

• The  relief valve is not a single use device and will relieve over and over. Unlike other manufacturers who offer a one-time use solution which requires you to purchase replacement units each time. Our less costly   relief valve will protect your plug for many uses.

• The  air relief valve on the LANSAS®  RUPTURE PROTECTED Pipe Plug begins to relieve air from the plug once is has been over-inflated by a maximum of 33% above the Required Inflation Pressure for the plug and resets (reseals) when the pressure is equalized at or just below the Required Inflation Pressure again.
