Aluminum Reducing Fitting for PPS Piping Systems

PPS1 UC-MRC Aluminum Reducing Fittings provide a direct transition between two different PPS aluminum pipe sizes. Designed for larger-diameter PPS networks, these reducers allow the main piping system to step down to a smaller pipe diameter while maintaining a compact inline connection.

Configurations are available from 2-1/2" x 2" through 6" x 4", providing reducing connections for compatible PPS compressed air, vacuum, nitrogen, and other approved PPS piping applications.

Useful when branching into lower-capacity sections of a system
Maintains compatibility with the PPS aluminum piping network

Compact PPS Connection

Purpose-built for PPS aluminum pipe
Reduces the need for multiple transition components
Available for larger industrial pipe diameters
Supports modular piping layouts
Suitable for new installations and system modifications

Common Applications

Piping Transitions

Main line size reductions
Distribution line transitions
Equipment supply piping
System extensions
Network modifications
Large-to-smaller pipe transitions

PPS Distribution Networks

Compressed air distribution
Industrial vacuum piping
Nitrogen distribution
Manufacturing facilities
Production systems
Industrial utility piping

Selecting the Correct Reducing Fitting

Select the reducer according to both PPS pipe diameters being connected. The first size identifies the larger pipe OD, while the second identifies the reduced pipe OD.

Available configurations are 2-1/2" x 2", 3" x 2-1/2", 4" x 3", and 6" x 4". Confirm both pipe sizes before ordering and review dimensions A and B where installation clearance is limited.

Installation Considerations

Confirm both PPS pipe outside diameters before ordering.
Match the larger and reduced connection sizes to the piping layout.
Review dimensions A and B to confirm installation clearance.
Use compatible PPS aluminum pipe and system components.
Prepare pipe ends according to PPS installation requirements.
Keep pipe ends and fitting connection surfaces clean before assembly.
Support larger-diameter piping appropriately around the fitting.
Do not exceed the published maximum operating pressure of 232 PSI.
Maintain the system within the published -4°F to 176°F operating temperature range.
Test the completed piping network before normal operation.
Install according to PPS system requirements.

Frequently Asked Questions

What is a PPS1 UC-MRC reducing fitting?

It is an aluminum reducing fitting designed to connect two different PPS pipe diameters in an inline piping configuration.

What reducing sizes are available?

Available configurations are 2-1/2" x 2", 3" x 2-1/2", 4" x 3", and 6" x 4".

What does the first size represent?

The first size identifies the larger PPS pipe outside diameter, while the second size identifies the smaller pipe outside diameter.

What is the maximum operating pressure?

The published maximum operating pressure is 232 PSI.

What is the operating temperature range?

The published operating temperature range is -4°F to 176°F.

Is the fitting made from aluminum?

Yes. These fittings are part of the PPS 100% aluminum network.

Can this fitting be used to reduce the size of a PPS main line?

Yes. The fitting provides a direct transition from the listed larger PPS pipe diameter to the corresponding smaller diameter.

Can these reducers be used in compressed air systems?

They can be incorporated into compatible PPS compressed air piping systems when the complete system is appropriate for the required operating conditions.

Can they be used in PPS vacuum systems?

They can be incorporated into compatible PPS vacuum piping networks when properly selected and installed for the intended service.

Can they be used in PPS nitrogen systems?

They can be incorporated into compatible PPS nitrogen piping networks when the complete system is designed for that service.

Why does the 6" x 4" fitting use an MRCC part number?

The 6" x 4" configuration is identified as PPS1 MRCC160100 within this reducing fitting family.

Where can I review the dimensions?

The dimensional table above lists dimensions A and B for each available configuration, and the complete specification sheet is linked in the Ask Willy section.
