General service expansion joint for high pressure applications

GARFLEX® 8100 expansion joints feature rugged yet flexible nylon cord reinforcement in a molded spherical bellows design that ensures an exceptional burst pressure rating. The streamlined flowing arch design reduces turbulence and allows smooth, quiet flow-no need to fill the arch and restrict its movement.

GARFLEX® 8100 meets the requirements of ASTM F1123 and Navy/Coast Guard Specification 46CFR56.60-25(E).
