RJT Stainless Steel Round Nut Union – 4-Piece Assembly

RJT Stainless Steel Round Nut Union – 4-Piece Sanitary Assembly

RR STEEL manufactures RJT stainless steel round nut unions for hygienic processing equipment, industrial stainless steel piping and compatible liquid cooling applications.

Featuring a detachable four-piece assembly, these unions provide a serviceable pipe connection for systems requiring installation flexibility, inspection and maintenance access.

SS304 and SS316L material options are available, with OEM manufacturing supported according to customer drawings and technical specifications.

What Is an RJT Round Nut Union?

An RJT round nut union is a detachable pipe fitting designed to connect matching stainless steel piping components through a union nut and sealing interface.

Unlike RJT hex unions that use hexagonal nuts, this configuration features a round union nut with an appropriate tightening profile.

Both designs belong to the RJT union family, but the nut structure and corresponding components must be matched to the specified assembly.

Key Features

• Four-Piece Assembly: Typical configuration includes a round union nut, two matching connection ends and a gasket.

• Material Options: Available in SS304 and SS316L stainless steel.

• Detachable Connection: Facilitates pipe installation, disassembly and maintenance.

• Round Nut Configuration: Provides an alternative to hexagonal RJT union nut designs.

• Precision-Machined Interfaces: Connection dimensions and sealing surfaces are manufactured according to specified requirements.

• OEM Production: Custom sizes, connection ends and assembly configurations are supported.

RJT Round Nut Union Components

A typical four-piece RJT round nut union consists of:

• RJT round union nut

• Matching male connection end

• Matching female connection end

• Suitable sealing gasket

The actual component arrangement, dimensions and gasket design should be confirmed using the applicable drawing or approved sample.

RJT Round Nut Union vs. RJT Hex Union

RJT round nut unions and RJT hex unions are both detachable stainless steel piping connections. Their primary distinction is the nut configuration and associated tightening method.

• RJT Round Nut Union: Uses a round nut with a suitable tightening profile.

• RJT Hex Union: Uses a hexagonal nut designed for wrench tightening.

Component compatibility depends on the connection dimensions and specified design. Different nut styles should not be assumed interchangeable.

Applications

1. Data Center CDU Liquid Cooling Piping

RJT stainless steel round nut unions may be used in compatible custom liquid cooling piping assemblies where detachable connections are required.

• Serviceable stainless steel coolant supply and return piping

• Custom liquid cooling distribution connections

• Maintenance-accessible pipe sections

• Selected CDU piping and manifold connection assemblies

Before selecting an RJT union for a liquid cooling system, verify operating pressure, temperature, coolant chemistry, gasket compatibility, connection dimensions and project-specific technical requirements.

2. Dairy Processing

RJT unions are commonly associated with dairy processing equipment and hygienic stainless steel piping systems.

3. Food and Beverage Processing

Suitable for detachable connections in compatible food and beverage production equipment, subject to the required material and hygiene specifications.

4. Industrial Fluid Handling

Applicable to industrial stainless steel piping systems where RJT connection geometry and sealing requirements are specified.
