ISOTECH® IEJ-CP-SWEAT Copper Pipe Internally Pressurized Expansion Joint, is designed for high-pressure applications, and is ideal for projects focused on durable, high-performance infrastructure. Available in sizes from ¾” to 4” this model accommodates a total 2” pipe movement—1½” in pipe expansion and ½” in contraction. At the heart of the Expansion Joint are multi-layered, corrosion-resistant stainless steel bellows, optimized for internal pressurization to maximize strength in compression. Reinforced by square telescoping shrouds, the bellows are safeguarded against misalignment, over-compression, and external damage. This design also ensures precise axial movement, maximizing durability and system reliability.For compact installations, the slim profile allows seamless setup in walls, floors, and confined mechanical areas. ISOTECH Expansion Compensators avoid costly structural modifications and rather offer a reliable and adaptable choice for high-stress environments.
