Description
90° Aluminum Union Elbow for PPS Piping Systems
PPS1 9C 90° Aluminum Union Elbows provide a 90-degree directional change between two sections of compatible, equal-size PPS aluminum pipe. The union elbow integrates directly into the modular PPS system while maintaining the corresponding pipe diameter through the fitting.
Available on this listing for pipe outside diameters from 1/2" through 4", these elbows can be incorporated into compatible PPS compressed air, vacuum, and nitrogen piping networks where a 90-degree change in direction is required.

Why Use a 90° Union Elbow?
Change Pipe Direction
- Creates a 90-degree change in the PPS pipe run
- Connects equal pipe diameters on both ends
- Useful for horizontal-to-vertical transitions
- Routes piping around walls, equipment, and structural features
- Provides a purpose-built directional fitting for PPS pipe
Modular PPS Installation
- Designed specifically for compatible PPS aluminum pipe
- Part of the 100% aluminum PPS network
- Supports new installations and system modifications
- Available across a broad range of pipe diameters
- Maintains a consistent pipe size through the elbow
Common Applications
Piping Direction Changes
- Horizontal-to-vertical transitions
- Vertical-to-horizontal transitions
- Routing around equipment
- Wall and ceiling piping
- Branch and main distribution layouts
PPS Distribution Networks
- Compressed air distribution
- Industrial vacuum piping
- Nitrogen distribution
- Manufacturing facilities
- Machine shops
- Production and process areas
Selecting the Correct Elbow Size
Select the PPS1 9C elbow according to the outside diameter of the PPS pipe being connected. Because this is an equal-size union elbow, both pipe connections correspond to the same pipe OD.
For example, the 2" PPS1 9C50 is designed to connect compatible 2" PPS pipe on both sides of the 90-degree turn. Confirm pipe OD before ordering and review dimensions A and B when installation clearance is limited.
Installation Considerations
- Confirm the PPS pipe outside diameter before ordering.
- Use the same elbow size as the pipe OD being connected.
- Review fitting dimensions to confirm installation clearance.
- Cut pipe square and prepare pipe ends according to PPS installation requirements.
- Keep pipe ends and fitting interiors clean before assembly.
- Use compatible PPS aluminum pipe and system components.
- Support piping appropriately around the directional change.
- 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.
- Installation should be completed by personnel familiar with the piping system and intended service.

Frequently Asked Questions
What is a PPS1 9C fitting?
PPS1 9C is a 90° aluminum union elbow designed to connect two compatible equal-size PPS pipe sections while changing the direction of the pipe run by 90 degrees.
What sizes are available on this listing?
This listing includes 1/2", 3/4", 1", 1-1/4", 1-1/2", 2", 2-1/2", 3", and 4" pipe OD options.
Does the elbow connect the same pipe size on both ends?
Yes. PPS1 9C is an equal-size union elbow, so both connections correspond to the same PPS pipe outside diameter.
Can these elbows be used in PPS compressed air systems?
Yes, when the selected fitting and piping components are suitable for the required compressed air operating conditions.
Can these elbows be used with PPS vacuum piping?
They can be incorporated into compatible PPS vacuum piping networks when correctly sized and installed for the system requirements.
Can these elbows be used with PPS nitrogen piping?
They can be incorporated into compatible PPS nitrogen piping networks when the system is designed and installed for that service.
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. The PPS1 9C elbow is part of the PPS 100% aluminum network.
How do I choose the correct elbow size?
Match the elbow size to the outside diameter of the PPS pipe being connected.
Where can I review the manufacturer's dimensions?
The PPS1 9C specification sheet is linked in the Ask Willy section directly above.
