    High-Temperature All-Metal Pipe Expansion Joints with Flanged Ends

    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).

    Pipe Expansion Joints with Threaded Ends

    Connect male threaded pipe to these expansion joints to add a point of flexibility in your line that reduces stress, vibration, and noise. These joints have a double-bulb design that absorbs more movement and vibration than other expansion joints. Made of neoprene, they’re more abrasion resistant than silicone rubber joints. Their flexible body is reinforced with nylon for added strength.

    Connect different pipe sizes in your line while adding a point of flexibility between them. These expansion joints absorb movement between two connected pipes to reduce stress, vibration, and noise. Their flanged ends mate with same-size Class 150 flanges without the need for a gasket. Each flange is supported by a zinc-plated steel plate. The body of these expansion joints is reinforced with cord for added strength.
    Your pipe system must be rigidly anchored on both sides of the expansion joint to control expansion or contraction of the line. When proper anchoring cannot be provided, limit rods (sold separately) are required.

    Clamp-On Pipe Expansion Joints for Drain, Waste, and Vent

    These joints are designed for vertical use to reduce stress, vibration, and noise in drain, waste, and vent systems. Slip them over the end of your pipe and tighten the band clamps for a secure hold. They have an internal stop to ensure pipe is in the proper position.
