When it comes to selecting a rubber expansion joint, there are several options available. General Rubber makes a variety of different styles, including the Series 1500 Ultra-Spool and the Series 301 single sphere with fluoroplastic liners. These two types are recommended for use in a variety of applications.
General Rubber’s Series 1500 Ultra-Spool
The Series 1500 Ultra-Spool rubber expansion joint is a hand-built product with precise measurements. This expandable joint provides precise markings and pressure ratings, as well as greater movement capabilities than standard narrow arch designs. These joints are available in a variety of sizes, materials, and configurations. They can accommodate media and can be filled with rubber foam when required.
It can also be used as a flex connector, as it can absorb vibration and noise from adjacent equipment. In addition, rubber expansion joints can be used for piping, and they can absorb temporary pipe movements and thermal growth. These expansion joints are also often used as a component of metal bellows expansion joint systems. They can also serve as pipe alignment guides, too.
Series 301 single sphere
The Series 301 single sphere rubber expansion joint is made with high-quality EPDM rubber and reinforced with nylon tire cords. This material is more flexible than Neoprene and has improved physical properties. It also features a galvanized steel floating flange that engages with the rubber beaded end. The flange is designed to rotate easily, facilitating a quick installation. This rubber expansion joint type of expansion joint is ideal for isolating small diameter piping from the vibration of mechanical equipment.
The Single Sphere joint offers 225 PSI of pressure capacity and temperatures up to 230 degrees F. It also reduces vibration, pulsation shocks, and noise transmission. The flanges feature a self-cleaning arch and can rotate 360 degrees for a tight connection.
Series 301 single sphere with fluoroplastic liners
Series 301 single sphere connectors are ideal for small stress motions and noise reduction, and they can be matched with spool type expansion joints to facilitate direct replacements. In addition, the ultra-small face-to-face dimensions make the Series 301 connectors easy to handle. They also meet and exceed the requirements of the Rubber Expansion Joint Division of the Fluid Sealing Association.
Series 301 EPDM connectors feature high-temperature EPDM rubber and are available with a tube and cover construction. They also feature galvanized ductile iron threaded female union ends. They are also available with a neoprene lining.
Style 301 single sphere
The Style 301 single sphere rubber expansion joint is ideal for applications where the expansion rate is small. Its unique design can withstand temperatures up to 230 degrees Fahrenheit. It also reduces vibration, pulsation shocks and noise transmission. The single sphere enables fast installation. The single sphere also has a self-cleaning arch, and a solid plate flange grips the sealing area for tight connection.
This style is available in a variety of sizes, from 1-1/2 inch up to 36 inches. It is available in single sphere and double sphere models. You can also choose arch-type or spool-type types, depending on your application.
Style 301 single sphere with fluoroplastic liners
Style 301 single sphere connectors are ideal for applications requiring small stress motions and noise absorption. They also match spool type expansion joints, making direct replacements possible. These new connectors are easy to handle and are made with a short face-to-face dimension. They also meet or exceed the specifications of the Rubber Expansion Joint Division of the Fluid Sealing Association.
