IS Gland-Pak Expansion Joints
The Type “IS” Gland-Pak is ideal for use where a guided expansion joint is desired, but where circumferential space is limited. IS type expansion joints use Gland packing rope which can be tightened in service. The gland design, using graphite rope, allows for complete in line field replacement of the packing. Flake graphite packing is not used in the IS design, eliminating any concern of minute graphite flakes entering the media flow.
