Product Description

Products Details

A grooved reducing cross is a pipe fitting that allows four pipes of different diameters to be connected in a cross configuration. It has three differently sized inlets for entering the pipe and a fourth, usually smaller, outlet. The “groove” aspect refers to the method of joining pipes, typically using grooves on the pipe ends along with gaskets and coupling systems to achieve a strong and sealed connection.

When using a grooved reducing cross to join two pipes, you will follow a similar process to other grooved fittings:

Grooving the Pipe Ends: Make sure the ends of the pipes you want to join are grooved. This involves creating a groove or notch in the end of the tube to facilitate a grooved connection.

Gasket Installation: Place a gasket in the grooved end of each pipe. Gaskets provide a seal between pipes to prevent leaks.

Locating the groove reducing spool: Insert the grooved end of the pipe into the appropriately sized opening on the groove reducing spool. Make sure the pipe fits securely into the groove.

Fitting installation: Place the fitting on the grooved end of the pipe, covering the gasket. The joint is responsible for holding the pipes together and maintaining the integrity of the seal.

Tighten the coupling: Use the required tools to tighten the coupling to ensure the connection is tight and leak-free. Follow the manufacturer’s specifications for torque or tightening procedures.

The exact steps may vary depending on the specific design of the groove reducing tee and the manufacturer’s guidelines. Be sure to refer to the manufacturer’s documentation and follow any applicable industry standards and codes for proper installation.

The groove connection method is commonly used in applications that require fast and reliable installation, such as fire protection systems, HVAC (heating, ventilation, and air conditioning) systems, and various industrial piping systems.
