Description
Prevost PPS1 MM Male NPT Straight Adapters
Transitions from PPS pipe to a male NPT threaded connection. Select the exact manufacturer part number and size from the options above.
Designed for Prevost Piping System (PPS). Match the PPS pipe outside diameter or specified CC interface. A similar nominal inch size does not establish compatibility with Infinity or another piping system.
What This Fitting Does
Transitions from PPS pipe to a male NPT threaded connection.
PPS fittings use the PPS Grip Concept to retain compatible aluminum pipe. Prepare pipe ends, insert to the prescribed depth and tighten to the manufacturer’s torque specification. Use Prevost’s installation instructions for the exact fitting and size.

Pipe size and thread size are separate specifications. PPS sizes identify the compatible pipe outside diameter. An NPT size identifies a tapered threaded port. Choose both correctly for adapters and threaded branch fittings. Product photos may show several sizes or configurations; the selected part number determines the item supplied.
