3/4 in. PVC Compression Coupling
Overview
The Midland 55304 is a 3/4 in. PVC compression coupling that joins two lengths of pipe with compression-nut ends instead of solvent cement. Both ends accept 3/4 in. pipe, making it a fast no-glue repair and tie-in fitting for water and chemical lines. The white Schedule 40 PVC body resists corrosion and most common dosing chemicals.

Frequently Asked Questions
Does this coupling need PVC cement?
No. The compression-nut design seals onto the pipe without solvent cement, so it can be installed and removed by hand or with a wrench.
Will it fit 3/4 in. PVC and poly pipe?
It is sized for 3/4 in. pipe; confirm your pipe outside diameter and wall fall within the gasket range before installing.
What pressure can it handle?
Treat it as a low-pressure water and chemical fitting and stay within the lower of the pipe rating and the system design pressure.
Is the material chemically resistant?
PVC resists many acids, bases, and salt solutions. Check the chemical compatibility chart for your specific fluid.
