Stainless Steel Reducing Ferrules for Sanitary Applications
When your process line requires a reliable, cleanable transition between two different tube sizes, a properly manufactured reducing ferrule makes all the difference. Tank Components Industries produces ferrule-to-ferrule reducers built to the exacting standards that pharmaceutical, food and beverage, biotech, and chemical processing operations depend on.
Whether you need to step down from a 6-inch line to a 2-inch connection or make a tighter 1-inch to 1/2-inch reduction, our reducing ferrules are engineered to fit, seal, and last.
What Makes TCI Reducing Ferrules Different
Every reducing ferrule we manufacture starts with SA479-316L stainless steel or nickel alloy stock — ASME-certified materials chosen specifically for their corrosion resistance, cleanability, and performance in demanding process environments. The result is a component you can count on across a wide range of industrial applications.
Each ferrule comes standard with a 30 Ra Max finish on both the ID and OD. This surface quality supports hygienic operation and is consistent with the demands of sanitary processing systems where contamination control is critical. Our ferrule-to-ferrule reducers are fully compatible with standard clamps and gaskets, so integration into your existing system is straightforward.
Available Sizes and Specifications
TCI reducing ferrules are available in 23 size combinations, covering reductions from 6 inches down to 1/2 inch. All sizes share a consistent 1.250-inch overall length, making them easy to plan for during vessel design or fabrication. Sizes available include:
| Size | Overall Length |
|---|---|
One of the most practical features of our reducing ferrule line is the ability to stack multiple reducers in sequence. Need to go from a 6-inch header down to a 1/2-inch port? You can accomplish that using any combination of our available sizes without custom fabrication.

Manufactured In-House to ASME Standards
Our reducing ferrules are produced entirely in our in-house machine shop at our 100,000-square-foot manufacturing facility in Springfield, Missouri. As a manufacturer that focuses exclusively on vessel components — not tank assembly — our entire operation is oriented around getting components right. We do not compete with the fabricators and OEMs we serve; we exist to support them.
All materials meet ASME certification requirements, and our production processes reflect more than 20 years of experience in stainless steel and nickel alloy component manufacturing. From pharmaceutical-grade sanitary fittings to heavy industrial ferrule reducers, we hold every part to the same standard.
Part of a Complete Sanitary Fittings Line
Reducing ferrules are just one component in our broader line of sanitary fittings and connections. TCI also stocks and manufactures tapered ferrules, heavy wall ferrules, light wall ferrules, ferrule caps, ferrule clamps, ferrule gaskets, tube adapter caps, weld sockets, and our proprietary TCI ClampConnects® and TCI BoltConnects® — all from the same ASME-certified stainless steel and exotic alloy materials.

Frequently Asked Questions
Q. What material are TCI reducing ferrules made from?
Our reducing ferrules are manufactured from SA479-316L stainless steel and nickel alloys, using ASME-certified material throughout. All ferrules come standard with a 30 Ra Max surface finish on both the ID and OD.
Q. What clamps and gaskets are compatible with TCI reducing ferrules?
TCI ferrule-to-ferrule reducers are designed to work with standard sanitary clamps and gaskets. Available gasket materials include Silicone (PC and PC Class VI), EPDM (White, Black, or Class VI), Viton (White or Black), and Teflon Envelope with EPDM or Viton insert.
Q. Can I stack reducing ferrules to achieve a larger size reduction?
Yes. TCI reducing ferrules are designed to be used in-line stacks, allowing you to reduce from 6 inches down to 1/2 inch — or any intermediate combination — using two or more ferrules in sequence.
Q. What industries do TCI reducing ferrules serve?
Our ferrules are commonly used in pharmaceutical, biotech, food and beverage, chemical, and extraction processing systems — anywhere sanitary, cleanable connections are required between different tube or pipe sizes.
Q. What is the overall length of TCI reducing ferrules?
All 23 standard size combinations share a consistent overall length of 1.250 inches.
