Rational 2067 Drilled Orifice Size 52

Product Description

The RATIONAL 2067 is a size 52 drilled orifice fitting used in commercial gas appliance systems. The orifice is drilled to size and marked for field identification, making it a direct-replacement component for gas burner assemblies. It controls gas flow by providing a calibrated restriction at a fixed internal diameter, which determines the fuel delivery rate to the burner. Installation is typically performed by a licensed commercial appliance technician or qualified gas service professional as part of a burner orifice replacement or gas conversion procedure.

This orifice is intended for use in commercial gas-fired cooking and food service equipment. It is suited to applications where a size 52 drilled orifice is specified by the equipment manufacturer. The marked sizing allows technicians to verify the correct orifice at a glance before and after installation, reducing the risk of misidentification in multi-orifice burner systems.

Key Features

• Drilled to size 52 for precise, calibrated gas flow restriction
• Marked for easy field identification and verification
• Direct-replacement design for commercial gas appliance burner assemblies
• Suitable for use in commercial cooking equipment service applications

Compatibility

Designed as an OEM-style replacement orifice for commercial gas appliance burner systems requiring a size 52 drilled orifice fitting.

Installation Notes

Installation must be performed by a licensed gas technician or qualified commercial appliance service professional in accordance with applicable local codes and IFGC guidelines. Shut off and lock out the gas supply at the service valve before removing or installing any orifice fitting. Verify the orifice size marking matches the equipment specification before installation. Do not enlarge or modify the drilled orifice, as altering the bore diameter will affect gas flow rate and combustion performance.
