Movement Capabilities
Style 9394
This multi-convoluted, lightweight expansion joint
is designed for low pressure applications that require
signifcant amounts of movement, axially and/or
laterally. Its low spring rates make it ideal for load cell
applications.
Note:
Flanged designs require retaining rings for an effective seal.
Sleeve type requires clamps; the overall length of the expansion joint
should include an additional 4" (101.6 mm) for clamping space.
