Heavy Duty High Pressure Grooved Flexible Coupling

Products Details

Heavy-duty grooved couplings, commonly referred to as heavy-duty grooved couplings, are a mechanical pipe joining system commonly used in fire protection, HVAC, and other piping applications. The joint consists of two pipe fittings with grooved ends and a gasket placed between them. These grooves are designed to provide a strong and rigid connection when the components are mechanically joined.

Known for their ease of installation, these couplings allow for quick connection of pipes without the need for welding, threading or flanging. Heavy-duty design for applications requiring greater strength and durability.

Standards governing heavy-duty grooved couplings are typically set by organizations such as the Mechanical Contractors Association of America (MCAA), the National Fire Protection Association (NFPA), or the International Organization for Standardization (ISO). The most widely recognized standard for grooved mechanical couplings is the Groove and Shoulder Joint Standard developed by the American National Standards Institute (ANSI) and the Manufacturers Standardization Society of the Valve and Fitting Industry (MSS).
