Description
Aluminum Male Thread Straight Fitting for PPS Piping Systems
PPS1 MM Aluminum Tapered Male Thread Straight Fittings provide a straight transition from compatible PPS aluminum pipe to a male NPT threaded connection. This fitting style is designed for connecting a PPS pipe run directly to compatible female-threaded equipment, valves, manifolds, regulators, and other system components.
The PPS1 MM family includes pipe outside diameters from 1/2" through 3" with male NPT connections from 3/8" through 3". Several pipe diameters are available with multiple thread sizes, so both connection dimensions should be confirmed before ordering.

- Production and process areas
Selecting the Correct Fitting
Select the PPS1 MM fitting according to both the PPS pipe outside diameter and the required male NPT thread size. Several pipe diameters have multiple MNPT options, so pipe size alone is not sufficient.
For example, 1" PPS pipe is available with 1/2", 3/4", or 1" MNPT connections. Confirm both the pipe OD and mating thread size before ordering.
Installation Considerations
- Confirm both the PPS pipe OD and male NPT size before ordering.
- Verify the mating component has a compatible female NPT connection.
- Review fitting dimensions when installation clearance is limited.
- Prepare PPS pipe ends according to system installation requirements.
- Use thread-sealing practices appropriate for the intended application.
- Keep pipe ends, fitting interiors, and threaded surfaces clean before assembly.
- Support connected piping and equipment appropriately.
- 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 PPS piping systems.

Frequently Asked Questions
What is a PPS1 MM fitting?
PPS1 MM is an aluminum straight fitting designed to connect compatible PPS pipe to a male NPT threaded connection.
Is the threaded connection male or female?
The threaded end is male NPT.
What pipe sizes are available?
PPS1 MM fittings are available for PPS pipe outside diameters from 1/2" through 3".
Why are there multiple fittings for the same pipe size?
Several PPS pipe sizes can be paired with different male NPT thread sizes, so both dimensions must be selected correctly.
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. PPS1 MM is part of the PPS 100% aluminum network.
Can these fittings be used in PPS compressed air systems?
They can be incorporated into compatible PPS compressed air piping systems when correctly selected and installed for the required operating conditions.
Can they be used with PPS vacuum or nitrogen piping?
They can be incorporated into compatible PPS vacuum and nitrogen piping systems when the fitting and complete system are appropriate for the intended service.
How do I select the correct fitting?
Match both the PPS pipe outside diameter and required male NPT thread size.
Where can I review the manufacturer specifications?
The PPS1 MM specification sheet is linked in the Ask Willy section directly above.
