Product Description

Grooved Flexible Couplings Description

Grooved Flexible Coupling is a cutting-edge mechanical connector designed for the seamless joining of pipes across a multitude of systems, including plumbing, HVAC, fire protection, and industrial applications. This coupling stands out for its incorporation of a flexible element, typically crafted from synthetic rubber or elastomer, which enables controlled movement and effectively absorbs vibration, shock, and thermal expansion.

Key Features:

  1. Available Sizes: Ranging from 1 to 12 inches, accommodating a wide variety of pipe diameters.
  2. Working Pressure: Rated at 300 PSI, ensuring robust performance under high-pressure conditions.
  3. Certifications: Boasts FM approval and UL certification, guaranteeing compliance with stringent safety and quality standards.
  4. Coating Options: Offers a selection of coatings including red painted, galvanized, epoxy blue, and grey, providing enhanced protection against corrosion and wear.
  5. Gasket Materials: Available in EPDM, NITRILE, and SILICON options, catering to different environmental and operational requirements.

Why Choose Grooved Flexible Coupling

Grooved couplings are designed to be easily installed on pipe ends, simplifying the installation process compared to other types of couplings.These couplings are designed to flex, allowing them to accommodate a degree of misalignment, deflection, and expansion/contraction within the duct system.Using grooved flex couplings can help reduce the transmission of noise and vibration through your ductwork.Grooved flex couplings help reduce maintenance requirements and increase uptime.Easy and fast installation, which can significantly save labor costs.

Design and Functionality:

Grooved flexible couplings are ingeniously designed to transmit torque while accommodating radial, axial, and angular misalignments. This flexibility allows for smooth bends in the piping system and the absorption of thermal expansion and contraction, potentially eliminating the need for traditional expansion joints and other expansion devices.
The coupling works by assembling a stretched rubber gasket, slightly smaller than the pipe diameter, between the two pipe ends to create an initial seal. The coupling halves are then placed around the gasket and bolted together, enhancing the sealing. Upon pressurization of the piping system, a “pressure reserve” is created by the gasket’s profile, pressing the sealing lips against the gasket seating surface to create a completely leak-proof and airtight connection.
