## Overview

The T/Y Corrugated Coupler by Cleveland Tubing is a flexible, durable connector designed to replace rigid tees and wyes. It fits 3” and 4” corrugated pipes as well as 4” PVC pipes, supports up to 70 psi, and features an adjustable swivel inlet for customizable angles, making it an essential, easy-to-install solution for versatile plumbing connections.

## Description

The FLEX-Drain 4 in. Polypropylene DWV Flexible Tee/Wye is ideal for use as a wye or tee in DWV applications. This connector features flexible construction that can bend to fit most angles. FLEX-Drain helps you get the job done faster and easier, with professional grade durability and more versatility than traditional corrugated pipe. Flexible, bendable and expandable, FLEX-Drain easily bends around any obstacle, hold its shape during installation and with a simple snap, its integrated soil-tight fittings lock securely and stay connected during backfilling. FLEX-Drain is a complete drainage solution system that's widely compatible with virtually all traditional 3 in. and 4 in. corrugated pipe and 4 in. PVC. Technologically superior, it's made with no-break copolymers and exceeds all applicable ASTM crush standards.

Review: Hard to find, but worth the search - I thought it was a bit expensive, but it is the only way that I could find to join two 4 inch drains into a single outlet. It is flexible and fits the 4" corrugated drain hoses perfectly, although the user should be prepared to tape the joints if water leaking is any kind of issue. Gorilla makes a special rubbery black duct tape that is a couple of dollars more than their very good black duct tape, and it prevents leaks at the joint.
Review: good value - does what it is supposed to do

**Q: How long is it overall**
A: The length is 9 1/2"

**Q: I am connecting to 3 inch pvc pipe, is this a friction fit or do i need to apply glue/solvent?**
A: It's more of a snap or press fit. No adhesive is required for lightly loaded connections.

**Q: I am using a 3" flexible drain (landscaping) drain pipe.....will this connector snap to fit that??**
A: I used small downspout screws to secure so it won't come off,
mine has been on over two years and still going strong.
I'm using two rain barrels and it works great!!!

**Q: I am connecting to 3 inch pvc pipe, is this a friction fit or do i need to apply glue/solvent?**
A: Friction was sufficient for my project, simple drain line

### ⭐⭐⭐⭐⭐ good value

does what it is supposed to do

### ⭐⭐⭐⭐ Thin . Is what it is..
*by T***K on October 7, 2025*

It is cheap made. Little flimsy to suit my liking. The y comes off when you go to snap it back on the main pipe the main pipe flexes in. That's how flimsy it is. The big box store sells the same one. I would like to have had a better option. I hope it doesn't come back to bite me.. I recommend trying to find a better option..... Was making a French drain....
