VIBRO CONNECTORS VRTF

VIBRO CONNECTORS VRTF is a high-performance vibration isolator and noise suppressor built for demanding piping systems. This advanced double sphere rubber expansion joint excels at absorbing multi-directional movement and maintaining system integrity under harsh operating conditions.

Superior Flexibility Through Double Sphere Design

The double sphere joint design offers a longer installation length than traditional single sphere joints — delivering greater flexibility and higher displacement capacity. This makes it the ideal solution for systems that require significant movement accommodation or complex piping layouts where space is limited and performance cannot be compromised.

Precision Engineering for Lasting Reliability

VIBRO CONNECTORS VRTF features a precision-molded dual sphere rubber body paired with robust flanged end connections. Together, they deliver outstanding elasticity and consistent, long-term reliability.

The specially formulated rubber compound actively dampens dynamic forces traveling through piping systems while effectively counteracting thermal expansion and contraction caused by temperature fluctuations.

Vibration Absorption & Acoustic Control

The flexible rubber element absorbs vibration energy before it reaches connected equipment — eliminating the need for it to travel through rigid piping. This protects downstream equipment and significantly reduces operational noise.

For environments where noise control is a priority, VIBRO CONNECTORS VRTF serves as an ideal acoustic solution, delivering measurable soundproofing performance across a wide range of installations.

Built for Diverse Industrial Applications

Operating within rated movement limits ensures maximum performance and long service life. VIBRO CONNECTORS VRTF is suited for a broad spectrum of industrial applications, including:

  • HVAC systems
  • Process piping
  • Pump connections
  • Facilities requiring intensive vibration control and acoustic treatment

Description

VRTF double sphere rubber expansion joints leverage the inherent advantages of advanced rubber compounds, offering:

  • High Elasticity & Flexibility: Accommodates axial, lateral, and angular displacements while maintaining structural integrity
  • Vibration & Noise Reduction: Effectively isolates mechanical vibration and suppresses noise transmission throughout the piping system
  • Media Compatibility: Available in various rubber formulations (e.g., NR, SBR, IIR, NBR, EPDM, CR, FKM) to suit specific chemical, thermal, and environmental conditions
  • Environmental Resistance: Provides excellent resistance to weathering, radiation, and corrosive media
  • Durability & Maintenance: Lightweight, easy to install, and maintain, with reliable sealing performance and long service life

Important Note: To prevent damage, the joint must be protected from sharp metal edges and must not be installed beyond its rated movement capacity.

Selecting the appropriate VRTF double sphere rubber expansion joint requires consideration of the following parameters:

  • Compatibility between the conveyed medium and selected rubber material
  • Full operating range of temperature, pressure, and vacuum
  • Required movement (axial, lateral, angular) based on system dynamics
  • Dimensional spacing between pipe flanges and connection type

With this information, our application engineers can assist in identifying the optimal joint configuration for your specific project requirements.

Due to its superior flexibility and vibration isolation properties, the VRTF double sphere rubber expansion joint is widely used in:

  • Raw Water & Sewage Transfer Systems
  • Cooling Water Circuits in Thermal Power Plants
  • Metallurgical and Chemical Process Pipelines
  • Condensate and Petrochemical Transport Lines
  • Flexible Connections in Long-Term and Temporary Installations
  • Granular, Powder, and Low-Temperature Gas Conveyance

Its wear-resistant rubber composition also makes it suitable for abrasive media and dynamic flow conditions across various industries.

For custom applications, OEM and ODM services are available. To determine the ideal double sphere rubber expansion joint, it is essential to evaluate:

  • Medium compatibility with selected rubber material
  • Full temperature, pressure, and vacuum range
  • Required movement characteristics
  • Flange-to-flange dimensions

Our engineering team is ready to support your selection process and ensure optimal performance for any application.
