High-Temperature All-Metal Expansion Joints with Flanged Ends
- For Use With: Air, Natural Gas, Oil, Steam, Water
- Temperature Range: -20° to 800° F
- Maximum Pressure: 150 psi @ 72° F
- Maximum Vacuum: 29 in. of Hg @ 72° F
These all-metal expansion joints can handle higher temperatures than rubber expansion joints. They reduce stress, vibration, and noise in piping systems by providing a point of flexibility to absorb movement. Joints are made of 304 stainless steel for very good corrosion resistance. The flanged ends rotate for easy bolt hole alignment during installation. Flanges mate with a same-size flat-surface Class 150 flange with a gasket (sold separately).
Liners (sold separately) slide into the expansion joint to provide a smooth interior for unrestricted flow.

Expansion Joints with Butt-Weld Ends
- For Use With: Air, Natural Gas, Oil, Steam, Water
- Temperature Range: -20° to 800° F
- Maximum Pressure: 150 psi @ 72° F
- Maximum Vacuum: 29 in. of Hg @ 72° F
These joints weld to unthreaded pipe or another butt-weld fitting for a leak-resistant, permanent connection. They reduce stress, vibration, and noise in metal piping systems by providing a point of flexibility to absorb movement.

Sanitary Expansion Joints with Flanged Ends
- For Use With: Beverage, Food, Nonabrasive Slurry, Water
- Temperature Range: -60° to 300° F
- Maximum Pressure: 150 psi @ 300° F
- Maximum Vacuum: 26 in. of Hg @ 72° F
- Specifications Met: FDA Compliant 21 CFR 177.2600
Designed for piping systems in breweries, food plants, and other sanitary environments, these flexible joints reduce stress, vibration, and noise by absorbing movement. Made of stainless steel, they won’t corrode from frequent washdowns with harsh cleaners. To eliminate crevices that could hold water and bacteria, the surface is highly polished. An interior silicone liner keeps out contaminants, too, while also damping sound and vibration. The liner is FDA compliant for direct contact with food. Flange gaskets are built into the liner, so these joints mate easily with Class 150 flanges, no additional gasket required. Limit rods protect them from overextension. These joints are not for use with steam.
