Series 1500 Ultra-Spool expansion joints are a domestic, hand-built product for the most demanding of applications. A precision built product designed to provide exacting specifications for tube and cover requirements, pressure ratings, markings, and special options. The wide arch will provide much greater movement capabilities than standard narrow arch designs. The tube can be constructed using a variety of elastomer products including EPDM, Chlorobutyl, Neoprene, Nitrile, Hypalon, Viton.

Style 1200 "Flexi-Spool" rubber expansion joints are designed to handle a multitude of industrial applications. "Flexi-Spool" expansion joints are a spool-type, hand-wrapped expansion joint with several construction features that provide advantages over standard expansion joints. The wide-arch style of "Flexi-Spool" provides several times the movement capability of standard narrow arch style joints.

A single sphere rubber expansion joint / flexible connector that is ideal for HVAC applications or general industrial installations. Capable of absorbing axial or lateral motion. Built-on steel flanges easily rotate for easy installation. Virtually eliminates vibration and noise caused by vibrating mechanical equipment such as pumps and chillers. EPDM tube and cover are high temperature rated. Built in standard face-to-face dimensions equal to single arch spool-type rubber expansion joints. Nylon reinforcing plies give Ultra Sphere expansion joints high working pressures.

A double sphere rubber expansion joint / flexible connector that is ideal for HVAC applications or general industrial installations. Capable of absorbing larger amounts of axial or lateral motion than single sphere products. Built-on steel flanges easily rotate for easy installation. 

A double sphere connector with built on metallic female NPT union ends. U303 connectors are available in standard or cabled styles. Choose either Neoprene or EPDM. Ideal for isolating noise and vibration between mechanical equipment and small diameter threaded piping. Style U303-EPDM has control cable assemblies attached to prevent over-extension. Factory installed steel body ring adds stability.

UNISOURCE SERIES ED. Style U expansion joints are elastomeric in both body and flange and are available in Neoprene, Hypalon, EPDM, Butyl, or fluoroelastomer Viton. Thinner in overall gauge than pressure piping expansion joints to protect thin wall duct systems. Style “U”, a U-joint without arch, designed for normal ducting movements. 

UNISOURCE SERIES ED. Style A expansion joints are elastomeric in both body and flange and are available in Neoprene, Hypalon, EPDM, Butyl, or fluoroelastomer Viton. Thinner in overall gauge than pressure piping expansion joints to protect thin wall duct systems. Style “A”, a rounded arch type joint, is designed for increased axial movement capabilities without pre-extension or compression. 

UNISOURCE SERIES ED. Style HA expansion joints are elastomeric in both body and flange and are available in Neoprene, Hypalon, EPDM, Butyl, or fluoroelastomer Viton. Thinner in overall gauge than pressure piping expansion joints to protect thin wall duct systems. Style “HA”, a sharp arch type joint, is designed for large movement capabilities without pre-extension or compression. 

Unisource metallic retaining rings are designed for use on all elastomeric expansion joints with duck and rubber flanges. Metallic retaining rings must be used when connecting the rubber flanges of expansion joints to the mating piping system flanges. Retaining rings consist of split circular sections of 3/8” thick carbon steel or stainless steel, drilled to match the expansion joint flanges. 

A control unit assembly is a system of two or more control rods placed across an expansion joint from flange to flange to minimize possible damage to the expansion joint caused by excessive motion of the pipeline. Standard control units assemblies consist of two rods, four triangular gusset plates, and necessary nuts, metal washers and rubber grommets.
