Designed to accommodate pipe movement, vibration, and thermal expansion, flexible grooved couplings provide a reliable and efficient connection solution for modern piping systems.
A flexible grooved coupling is a mechanical pipe coupling designed to connect grooved-end pipes while allowing controlled angular deflection, axial movement, and vibration absorption.
Compared with rigid couplings, flexible grooved couplings help protect piping systems from stress caused by thermal expansion, seismic activity, and equipment vibration.
They are widely used in fire protection, HVAC, water supply, and industrial piping systems where flexibility and system protection are required.
Allows angular deflection and axial movement without pipe damage
Absorbs vibration and noise from pumps and mechanical equipment
Reduces stress caused by thermal expansion and contraction
Provides fast installation without welding or threading
Easy inspection, maintenance, and system modification
For a complete product range, please check our grooved pipe fittings and couplings.
Flexible grooved couplings are commonly used in:
Pipe Size Range: DN50 – DN300 (2” – 12”)
Working Pressure: Up to 2.5 MPa / 363 PSI (depending on size)
Working Temperature: -30°C to +110°C (with EPDM gasket)
Angular Deflection: Up to ±3° per joint (size dependent)
Connection Type: Grooved-end pipe connection
Flexible grooved couplings are manufactured using high-strength ductile iron for excellent durability and pressure resistance.
Standard surface finishes include epoxy coating, hot-dip galvanizing, or painted finishes to ensure corrosion protection in various operating environments.
Gaskets are available in EPDM, NBR, or silicone rubber to meet different temperature and media requirements.
Installation of a flexible grooved coupling is simple and efficient. After aligning the grooved pipe ends, the gasket is positioned over the joint, followed by housing installation and bolt tightening to the specified torque. This method significantly reduces installation time while ensuring a secure and leak-free connection.
Flexible grooved couplings can be manufactured to comply with:
ANSI / AWWA standards
ASTM material specifications
ISO quality management systems
FM Approved / UL Listed (upon request)
Compliance with international standards ensures reliable performance in critical piping systems.
