3/8 in. x 1/4 in. Female NPT Schedule 80 PVC Reducer
3/8 in. x 1/4 in. Female NPT Schedule 80 PVC Reducer
Overview
The MPN 830052 is a Schedule 80 PVC reducer coupling that steps 3/8 in. female NPT down to 1/4 in. female NPT, letting you transition pipe size in a threaded run. Both ports are FPT, with 3/8-18 and 1/4-18 threads. Gray Schedule 80 PVC handles corrosive fluids and moderate pressures common in metering and process piping.

Frequently Asked Questions
Which end is the larger size?
One port is 3/8 in. female NPT and the other is 1/4 in. female NPT, so it reduces from 3/8 in. piping down to 1/4 in.
Are the connections threaded?
Yes, both ports are female NPT (FPT). The joint is sealed with thread tape or pipe dope; no solvent cement is required.
How tight should I make plastic NPT threads?
Hand-tighten, then add only one to two turns with a wrench. Overtightening PVC threads can crack the fitting.
Is it chemical resistant?
Schedule 80 PVC resists many acids, bases, and salts. Confirm your specific media against a PVC chemical compatibility chart.
