Flexible and shielded couplings
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.

Clamps
Couplings
Join pipe of the same or different materials and sizes.
Standard Flexible Couplings
The 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 USA · AIS/BABA
Pipe Sleeve Seals
Close the gap where a pipe runs through a sleeve in a foundation wall, where your inspector accepts it.
¾″ to 4″ pipe

Shielded transition coupling
Proflex
Shielded coupling for above-ground pipe transitions. A flexible seal wrapped in a stainless steel shield that resists shear and holds the joint rigid and aligned.
Code-compliant connection · Residential and commercial DWV · ¾″ to 8″
Made in USA · AIS/BABA
No-Hub Couplings
Shielded couplings for no-hub cast iron, in Standard, Medium and Heavy Duty.
1½″ to 15″
Made in USA
Chemical Couplings
An FEP barrier inside a flexible coupling for chemical-waste drainage.
Labs, medical, processing plants
Socket Couplings
Clamps over a PVC or ABS fitting hub. Tie in cast iron or change size right at the hub.
1½″ to 4″
Made in USA · AIS/BABA
Fittings, caps and accessories
Change direction, take up movement, cap a line or replace a clamp.
Qwik Tees, Ells and Wyes
Flexible tees, ells and wyes for repair and alteration work. No primer or cement, and they come back apart.
1½″ to 4″

Which one?
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.
Flexible
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
Shielded
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.
