Expansion Joints with Flanged Ends
These joints reduce stress, vibration, and noise in piping systems by providing a point of flexibility to absorb movement. The flanged ends rotate for easy bolt hole alignment during installation. They mate with a same-size flat-surface Class 150 flange without the need for a gasket. Joints have a flexible body that is reinforced with nylon for added strength.

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 Sealing Flanged Ends for Metal Pipe
Because the flanges are molded into the body for a wide sealing surface, these joints provide a tighter seal than other expansion joints. Each flange is supported by a zinc-plated steel plate. Flanges mate with a same-size flat-surface Class 150 flange without the need for a gasket. Joints reduce stress, vibration, and noise in metal piping systems by providing a point of flexibility to absorb movement. They have a flexible body that is reinforced with cord for added strength.

Chemical-Resistant Expansion Joints with Flanged Ends
- For Use With: Coolant, Hydrochloric Acid, Water
- Temperature Range: -0° to 400° F
- Maximum Pressure: 130 psi @ 72° F
- Maximum Vacuum: 29 in. of Hg @ 72° F
The PTFE body on these expansion joints has a super-smooth surface that stands up to corrosive chemicals. Joints have a triple-bulb design that provides excellent vibration absorption, reducing stress on your piping system. The flanges mate with a same-size flat-surface Class 150 flange without the need for a gasket. Limit rods are attached to the flanges to prevent overextension.

Clamp-On Expansion Joints
- For Use With: Calcium Chloride, Oil, Petroleum, Sewage, Sludge, Sodium Carbonate (20% in Water), Water
- Temperature Range:
Neoprene Rubber: -20° to 220° F
Silicone Rubber: -75° to 500° F - Maximum Pressure: 150 psi @ 72° F
- Maximum Vacuum: 20 in. of Hg @ 72° F
Slip these joints over your pipe ends and tighten the band clamps for a secure hold. Joints have a triple-bulb design that provides excellent vibration absorption to reduce stress on your piping system. They also have reinforcing rings for extra support during pressure surges and in vacuum applications.
Neoprene rubber joints are more abrasion resistant than silicone rubber joints.
