Clamp-type Rubber Expansion Joint
The Clamp-type Rubber Expansion Joint is a flexible joint designed for easy installation and disassembly. Instead of traditional flanged or threaded connections, this joint uses metal clamps (usually stainless steel) to secure both ends of the rubber bellow to the pipeline. It is widely used in low-pressure systems such as HVAC units, water pumps, drainage lines, and compact piping networks where space is limited and maintenance needs are frequent.
KKT Type Molded Clamp Expansion Joint
The KKT type molded clamp expansion joint is manufactured with an integrated molding process and secured with stainless steel clamps for quick installation and removal. Made from high-elasticity rubber or silicone, it provides excellent flexibility and sealing performance, making it ideal for piping systems that require fast connection, disassembly, and maintenance.
Features
Molded Construction: One-piece molded body ensures precise dimensions and higher strength.
Easy Installation: Clamp connection design eliminates the need for flange bolts, enabling quick assembly and disassembly.
Excellent Sealing: Reliable pressure resistance and sealing performance to prevent leakage.
Material Options: Available in EPDM, NBR, silicone, and other materials to meet different media requirements.
High Flexibility: Effectively compensates for pipe displacement and absorbs vibration and noise.
Applications
Sanitary piping systems in food and pharmaceutical industries
Water supply, drainage, and HVAC pipelines
Chemical and light industrial fluid transfer
Marine and shipbuilding piping systems
Temporary or mobile piping requiring fast installation and maintenance
Clamp-Type Silicone Expansion Joint
Our clamp-type silicone expansion joints are highly flexible and customizable. We accept orders starting from just one piece, and the length, size, and dimensions can all be manufactured according to customer drawings. This makes them especially suitable for projects requiring non-standard or tailored solutions.
Key Point: The main limitation of silicone clamp joints is their low pressure resistance. They are typically designed for working pressures below 0.6 MPa, which makes them ideal for large-diameter

Ordering Information
When ordering Clamp Rubber Expansion Joints, please make sure to confirm the following details to ensure accurate product matching and safe installation:
Nominal Diameter and Pipe Outer Diameter: Clamp-type joints rely on a precise fit to the pipe. Please confirm the exact outer diameter of the connected pipe.
Working Pressure and Temperature: Provide accurate data for system conditions to ensure proper material selection and performance.
Medium Type: Let us know whether the medium is water, air, oil, chemical, or others to choose the suitable rubber compound.
Rubber Material Requirement: Different media and temperatures require different rubber types (e.g., EPDM, NBR, Neoprene).
Installation Environment: If the joint will be used in an outdoor, corrosive, or high-vibration area, please inform us for suitable reinforcement.
Clamp Type and Material: We offer stainless steel or galvanized clamps; let us know if you have special preferences or standards.
Since clamp-type joints rely on flexible sealing and external clamping pressure, proper size matching and clamp tightening are critical to performance and leak prevention.
