Description

308/311 series expansion joints


The Original Multi-Ply Expansion Joint – Always Ask For Keflex™

Keflex™ 308 and 311 Series Multi-Ply Expansion Joints are the premier expansion joints in the industry. They offer the ultimate solution to piping thermal expansion problems. A wide variety of end configurations are available and pressure ratings range from vacuum to 600 PSI at room temperature.  Designed and manufactured in accordance with EJMA standards.

A variety of materials are also available for any type of media, including highly corrosive acids or gases. Keflex™ Multi-Ply Expansion Joints have a softer spring rate compared to other expansion joints with the same dimensions, making them easier to install, and requiring less force to actuate in service. The inner section of the engineering brochure, accessed through the link below, highlights the advantages of the multi-ply construction.
