Reducing Bushing 1-1/4" x 1" Polypropylene

This Banjo RB125-100 reducing bushing connects a 1-1/4 inch male NPT thread to a 1 inch female NPT thread. It is moulded from black polypropylene and rated to Schedule 80 dimensions. The fitting handles a maximum operating pressure of 300 psi within a service range of -20 to 150 degrees Fahrenheit.

Suits Schedule 80 systems needing a 1-1/4 to 1

Installers working with Schedule 80 polypropylene pipe in agricultural, industrial or chemical-transfer plumbing will find the correct thread match and pressure rating here. Buyers who need a different thread standard, a metal body or a larger step-down size should look at other fittings.

300 psi maximum operating pressure at Schedule 80

The 300 psi rating at Schedule 80 wall thickness is the single figure that confirms whether this bushing meets the system design pressure. Verify that your piping schedule and pressure requirements align with this rating before purchasing.

Questions about this item

What does the 300 psi rating mean when this bushing is installed in a working system?

It indicates the maximum operating pressure the polypropylene bushing can handle at temperatures up to 150°F; system pressure must stay below this limit.

How do the NPT threads with 11-1/2 threads per inch affect what pipe this fits?

The male 1-1/4" and female 1" NPT threads follow the 11-1/2 TPI standard, so they mate only with matching Schedule 80 NPT fittings.

What clearance and alignment does the 1-1/2" overall length require during installation?

The 1-1/2" overall length sets the engaged depth between the male and female threads, so the piping layout must allow that exact spacing.
