This is a good quality runner jointing with an insertion of fabric to give additional strength and prevent spread under compression. Recommended for water and very low pressure steam gaskets.

Concept

Rubber insertion jointingis essentially a packing to provide leak proof joint to prevent vacuum resulting to air, water and steam pressure.

Application

It is extensively used on calorifiers as a leak proof jointing device between flanges, for water pressure when it is used with a furnace balloon or process system.
