This multi-convoluted, lightweight expansion joint is designed for low pressure applications that require significant amounts of movement, axially and/or laterally. Its low spring rates make it ideal for load cell applications. Benefits - Lightweight design installs easily, costs less to ship
- Can be custom-designed for even greater movement capability
- Choice of construction materials suitable for wide range of temperatures
- Available in flanged or sleeve type design, up to 48" (1219 mm) I.D.
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. Pressure
- Without external reinforcing rings: up to 3 psi (0.2 bar)
- With external reinforcing rings: up to 15 psi (1.0 bar)
Vacuum
- Without internal reinforcing rings: up to 3 inches (75 mm) Hg
- With internal reinforcing rings: up to 15 inches (381 mm) Hg
Contact Garlock if higher vacuum or pressure ratings are required. Movement Capabilities
- 3/4" (19 mm) axial compression per convolution
- 5/8" (16 mm) axial elongation per convolution
- 5/8" (16 mm) lateral deflection per convolution
Movements are non-concurrent.Larger convolutions are available to provide more movement. Contact Garlock if above listed movements need to be exceeded. Alternate Tube and Cover Materials
- Neoprene
- Nitrile
- Hypalon*
- Natural/gum rubber
- EPDM
- FDA Neoprene
- FDA EPDM
- Viton*
