High Demand Item – Frequently Reordered by Contractors

Fernco Proflex is the all-stainless shielded transition coupling for dependable above-ground pipe connections. A flexible neoprene sleeve seals the joint while a full .012″ type 301 stainless steel shield and clamp bands lock it rigid — so the connection resists shear forces, vibration, and shifting that would loosen an unshielded coupling.

From 1-1/2″ to 8″, the 3000 series joins cast iron, plastic, steel, and extra-heavy cast iron in straight and reducing sizes. Each gasket is marked with the part number and application, and the whole assembly is built from 300-series stainless for corrosion resistance.

Applications

Above-ground cast iron, plastic and steel DWV transitions
Connecting extra-heavy cast iron to standard pipe
Sewer, waste and vent connections needing a rigid, shielded joint
Repairs and remodels where a shielded coupling is specified

Best Used For

Above-ground DWV, sewer, waste and vent transitions
Connecting dissimilar pipe materials on a rigid, shear-resistant joint
Repairs and remodels where a banded coupling needs the strength of a shield
Commercial and residential plumbing where code calls for a shielded coupling

FAQ

Above ground or buried?

Proflex is engineered for above-ground transitions. For buried joints under heavy earth load, use a Fernco Strong Back RC shielded coupling instead.

What does the 3000 series connect?

Cast iron, plastic, steel, and extra-heavy cast iron to one another. For a transition to copper, use the Fernco 3001 series.

Why a shielded coupling?

The stainless shield keeps the joint rigid and resists shear, so the connection won’t sag or pull under vibration the way an unshielded rubber coupling can.

Why Contractors Choose This

Full stainless shield holds the joint rigid where rubber-only couplings flex
One coupling makes a clean material transition above ground
No primers, glue or cure time
