10" to 4" Tri-Clamp Concentric Reducer

Turn a 10" opening into a working 4" port.

This solid 304 stainless concentric reducer takes a 10" Tri-Clamp opening down to 4", so you can mount standard 4" TC gear — still columns, condenser hardware, sight glasses, butterfly valves or a simple blind cap — directly on the manway or top port of a commercial-scale tank. No adapters, no improvising.

Key points

• 10" → 4" — clamps onto any standard 10" TC ferrule and presents a standard 4" TC connection on top.
• Opens up the 4" ecosystem — pair it with the 4" Band Clamp, 4" Tri-Clamp Gasket and any 4" TC accessory.
• One-piece, heavy-gauge 304 — sanitary finish, clamps and seals like any standard Tri-Clamp fitting.
