Redflex Expansion Joints
Cost-Effective Solution for Flow Control Problems
Red Valve manufactures a complete line of Redflex Expansion Joints, rubber fittings and rubber pipes. Expansion joints are designed to alleviate piping stress, compensate for movement, reduce noise, and isolate vibration.
Redflex products can be custom-built in a variety of styles and configurations to accommodate pipe size reductions, misalignments and offsets. Red Valve offers flanged and slip-on connections, single or multiple arches, and a range of elastomers to meet process conditions.
​
The Redflex product line also includes rubber fittings, rubber elbows, vibration pipe, and rubber pipe to accommodate radius turns. Red Valve also custom builds many unique rubber products, such as headers with multiple pipe connections.
-
Series J-1 & J-1 Wide Arch Redflex Flanged Expansion Joints are used to compensate for pipeline movement and vibration. The construction of a Redflex Expansion Joint is very much like a heavy-duty truck tire - layers of high-quality elastomers are reinforced with steel wires and synthetic fabrics.
-
The inner layer forms a tube that extends through the inside of the joint and across the face of the end flanges. This layer is chosen based on its chemical compatibility and abrasion resistance and temperature rating to the process material.
-
The middle layer of the joint contains the bias-ply synthetic fabric reinforcement that gives the joint its form and pressure rating, and a layer of wire reinforcement for added strength.
-
The outer layer of the joint is chosen to be compatible with the environment in which the joint is to be installed - usually Neoprene or Butyl. This allows the joint to stand up to occasional contact with oils, corrosion and weathering
-
Redflex Expansion Joints features full-face integral flanges that eliminate the need for additional gaskets when installing the joint. The flanges are drilled to mate with ANSI 125/150 flanges, with special drilling available upon request. Galvanized or stainless steel retaining rings can be provided to protect the flange and distribute forces evenly. Redflex Expansion Joints can also be manufactured to meet Coast Guard and military standards as well.
-
Redflex Expansion Joints are available with a single arch, double arches or triple arches to meet the face-to-face and movement requirements of the installation. The arches, along with the flexibility of the elastomer construction, allow the J-1 to provide stress relief in piping systems due to thermal expansion and contraction, mechanical movements and vibration. Special multiple arch designs, filled arches and wide arches are also available.
-
Red Valve's J-10, J-11, R-4 & R-3 Concentric and Eccentric Redflex Reducing Expansion Joints are designed to allows simple connection of different sized pipes. Reducing Expansion Joints also provide all of the benefits of a Redflex Expansion Joint. Reducers can be used as pipe reducers or increasers, expansion joints, flexible connectors and vibration eliminators.
-
Redflex Reducers were designed to replace metal reducers in the pipeline. Standard reducers have a smooth-walled reduction from flange to flange. Reducing Expansion Joints are available in single, double and triple arches, in either open or filled models. The multiple arches are used in applications where expansion or contraction will occur.
-
The advantage of an all-rubber reducer over a metal reducers is the flexibility and durability of the elastomer. Filled reducers are usually used on slurry and abrasive applications to prevent the collection of material, which can settle in the arches. Redflex Reducers eliminate noise and isolate vibration in the pipeline, reduce stress, eliminate electrolysis and protect against start-up surges. Concentric reducers save installation space and reduce costs.
-
Red Valve manufactures concentric reducers to meet your exact piping needs. The flanges are designed to meet ANSI Class 125 drilling. Redflex Reducers are available in a variety of elastomers to satisfy the chemical compatibility and temperature of the process fluid. Piping systems must be anchored when using concentric reducers. Standard control rods cannot be used to prevent overextension or elongation. This is particularly of concern in larger diameter sizes, over 12”, where the smaller end joint control rods have a lever effect. Special design control rods with backup plates may need to be engineered.

Red Valve manufactures Series SL-53, SL-50 & SL-100 Redflex Slip-On Expansion Joints to suit special low-pressure applications where a quick installation is important. The SL-50 Expansion Joint is designed to be quickly installed onto standard schedule 40 pipe. It uses slip-on connections with stainless steel mounting bands for a secure connection. The SL-50 features an inner tube that is chosen to be compatible with the process material, a middle layer containing fabric and wire reinforcement, and an outer layer to protect the joint from occasional contact with oils, corrosion and weathering. The SL-50 can be constructed in custom lengths, with custom cuff I.D. and custom configurations.
-
Slip-on Series SL-53 Triple Arch Expansion Joints are designed to allow for greater contraction, expansion and lateral movement than the SL-50. The internal diameter of the SL-53 is equal to the outside diameter of replacement pipes. The SL-53 slips over the ends of an open pipe and is secured by clamps. Construction consists of a tube made of natural or synthetic rubber, a hand fabricated body consisting of high-quality synthetic fabric for reinforcement, and a cover wrap used to protect the unit against occasional contact with oil, weathering, ozone and corrosives. The SL-53 Triple Arch Expansion Joint is simple and economical to use. The SL-53 Expansion Joint will absorb movement from vibration, thermal expansion and contraction, and allow for misalignment of piping.

Red Valve offers a complete line of Rectangular, Circular and Custom Fabricated Redflex Ducting Expansion Joints. Our ducting joints are available in a variety of different elastomers to match your chemical and temperature requirements. Custom back-up rings in galvanized or stainless steel are also available.
-
Redflex Ducting Expansion Joints are designed for use on lightweight ductwork commonly found in odor control, air handling and vapor / heat / dust recovery systems. The flexible rubber construction of the joint accommodates motion caused by biaxial, lateral, torsional and angular movements concurrently. The rubber also helps to absorb the vibration of fans, reducing stress on the ductwork.
-
Redflex Ducting Joints are available in a variety of sizes and styles to meet any need. Our ducting joints are also used in a variety of municipal and industrial applications such as power plants, FGD systems, HVAC, odor control systems, aeration and military vessels.

Redflex Rubber Fittings & Elbows are strong, durable and flexible. They reduce noise and vibration from pumps, compressors and other equipment, and allow for minor misalignment where abrasion or corrosion will damage normal piping. Standard construction is a rubber tube with cotton duck reinforcement and a synthetic cover, for use with maximum continuing temperatures up to 180°F. For extra strength, spiraled steel wires are embedded in the body of the elbow from flange to flange. Redflex Rubber Fittings have a 50 psi working pressure standard, maximum of 75 psi, and can withstand 10" Hg vacuum. Can be manufactured with full vacuum upon request.
-
Standard fittings include 90° long and short radius elbows, 45° elbows, crosses, Y and T connections. Red Valve also has produced a wide range of custom configurations with multiple connections, integrated expansion joints and much more. Contact Red Valve with your custom needs and see how we can provide a solution.
