Above Ground Connections
Couplings, fittings and caps for drain, waste and vent pipe above grade. Join different pipe materials and sizes, fix a broken run, or cap it for a test.
Couplings
Join pipe of the same or different materials and sizes.
Standard Flexible CouplingsThe flexible coupling that started it all. Joins pipe of different materials and sizes, and many local codes accept it below ground. Some codes call for a shielded coupling above ground, and for most jobs we recommend one.¾″ to 27″Made in USAAIS/BABAView product ›
Pipe Sleeve SealsClose the gap where a pipe runs through a sleeve in a foundation wall, where your inspector accepts it.¾″ to 4″ pipeMade in USAAIS/BABAView product ›

Flexible or shielded
Both seal with a flexible sleeve and stainless steel clamps. The shield adds strength, and it’s what we recommend for most jobs.
Standard Flexible Couplings
The elastomeric body conforms to the pipe and makes up for differences in outside diameter between pipe materials. Stainless clamps compress it evenly for the seal.
- Accepted below ground under many local codes
- Joins different materials and sizes
Proflex and No-Hub
A stainless steel shield wraps the sleeve. It resists shear and keeps the joint rigid and aligned for a code-compliant connection.
- Proflex for material transitions
- No-Hub for no-hub cast iron
Codes vary by location, soil and climate. Check with your local code official before you install.
