Dn110 Pvc Pipe Flexible Coupling Clamp Type Rubber Expansion Joint for Plastic Pipes
Clamp Type Rubber Expansion Joints are flexible connectors made of high-quality rubber, designed to absorb vibration, noise, thermal expansion, and minor misalignments in piping systems.
Unlike flange-type joints, clamp type joints are secured using stainless steel clamps, making installation and maintenance fast and easy without the need for bolt alignment or flange drilling.
Key Features:
Quick Installation: Uses clamp rings instead of bolted flanges, saving time and labor.
Flexible Movement: Allows axial, lateral, and angular movements.
Vibration & Noise Reduction: Excellent dampening for mechanical vibrations and noise transmission.
Corrosion Resistant: Available in EPDM, NBR, or Neoprene rubber with stainless steel clamps.
Leak-Proof Seal: Tight and secure sealing ensures reliable performance under pressure.
Compact Design: Space-saving design ideal for compact or mobile installations.

Industry Applications
HVAC Industry
“Flexible enough to fit in compact HVAC pipelines, this joint eliminates vibration from chillers and pumps – ensuring quieter operation and longer equipment life.”
Water Treatment
“EPDM clamp joints are ideal for water filtration systems and pump outlets – offering corrosion resistance and leak-free performance.”
Marine & Shipbuilding
“Clamp-on rubber bellows absorb engine vibrations and pipe movements on ships, while stainless steel clamps resist saltwater corrosion.”
Chemical & Oil
“NBR clamp joints provide a safe and flexible connection in chemical and oil pipelines where flanged connections are impractical.”
Installation Instructions:
Ensure pipe ends are clean and aligned.
Insert the rubber joint between the pipe ends.
Place the stainless clamps around both ends of the joint.
Tighten clamps evenly using a screwdriver or torque wrench.
Re-check clamp tightness after 24 hours of operation.
✅ Pro Tip:
For high-pressure or vertical installations, use control rods or limiters to prevent axial pull-out.
FAQ
Q1: Can this joint be used for hot water or steam?
A : Yes, EPDM material supports up to 120°C. For steam applications, please consult us for a special rubber formulation.
Q2: Is flange welding required?
A : No. This clamp-type joint is flange-free and requires only stainless steel clamps for sealing.
Q3: Can I use it in chemical pipelines?
A : NBR is suitable for oil and some chemicals. For highly corrosive fluids, we recommend consulting us for fluorine-lined options.
Q4: How long is the service life?
A : Typically 5–10 years under normal use. Regular inspection is recommended for long-term reliability.
Q5: Do you offer OEM or custom services?
A : Yes! We support OEM branding, custom sizes, materials, and packaging.
