Tri Clamp Dimensions & Sizing Guide
Tri Clamp fittings (also known as Tri Clover or sanitary fittings) are widely used in food, beverage, pharmaceutical, and biotech industries due to their hygienic design and ease of use. Understanding how Tri Clamp sizing works is essential for choosing the right components for your system.
1. How Tri Clamp Sizes Are Defined
Nominal Tri Clamp sizes refer to the outer diameter (D1) of the tubing, not the flange or clamp size.
2. What Makes a Complete Tri Clamp Connection?
A full Tri Clamp connection consists of:
- Two ferrules (welded or attached to tubing)
- One clamp (to secure the ferrules)
- One gasket (placed between the ferrules to ensure a seal)
All parts must match the same nominal size (e.g. 2") for a leak-free, secure connection.
3. How to Measure Tri Clamp Components
Here’s how to correctly identify sizing:
- Ferrule: Measure the Tri-Clamp clamp size (referred to as Ferrule OD in the image and table below), as well as the required pipe inner diameter (D2) or outer diameter (D1), depending on which is relevant or measurable in the specific situation.
- Clamp: Fits around the flange outer diameter (Ferrule OD)
- Gasket: The outer dimension of the gasket depends on the Tri-Clamp size (Ferrule OD). Ideally — and especially in areas with sanitary requirements — attention should also be paid to the inner diameter of the gasket, selecting it to match the inner diameter of the pipe used (D2). This latter note applies to those Tri-Clamp sizes that can be used with pipes of different diameters

The Ultimate Guide to Butterfly Valves vs Ball Valves in Brewing: Which is Best for Your Brewery?
Applications in Brewing
Butterfly Valves:Butterfly valves are widely used in brewing due to their compact design and ease of operation. They are particularly suitable for applications where space is limited and where quick, frequent operation is required. These valves are excellent for controlling the flow of liquids in processes such as transferring wort, water, and cleaning solutions. Their simple design makes them ideal for use in various stages of brewing, from the mash tun to the fermenter.
Ball Valves:
Ball valves are known for their durability and tight sealing capabilities. They are often used in situations where a complete, leak-proof shut-off is required. In brewing, ball valves are typically used in high-pressure applications and where precise control of the liquid flow is crucial. They are commonly found in systems dealing with carbonation, yeast propagation, and other areas where maintaining pressure integrity is essential.
Cleaning and Sanitation of Brewing Valves
One of the primary differences between ball valves and butterfly valves is their ease of cleaning and sanitation. Butterfly valves are easier to clean and sanitize compared to ball valves. The flat disc design of butterfly valves allows for better cleaning in place (CIP), reducing the need for disassembly. A commercial brewery even had to make a sour beer due to contamination from a ball valve, which was then replaced with a butterfly valve. This incident highlights the importance of valve design in maintaining hygiene in the brewing process.Ball valves, on the other hand, have more crevices where gunk can accumulate, requiring disassembly for thorough cleaning. While many ball valves designed for the brewing industry come with features that facilitate easier cleaning, such as full port designs and sanitary fittings, they still pose a higher risk for contamination if not properly maintained.Flow Obstruction and Pressure Drop in Brewing Valves
Ball Valves:Ball valves have an unobstructed flow path when fully open, which allows for smooth liquid transfer without any resistance. This design feature makes ball valves highly efficient for applications requiring a free-flowing stream. Due to their unobstructed flow path, ball valves tend to have a lower pressure drop compared to butterfly valves. This characteristic makes them suitable for applications where maintaining pressure is critical.
Butterfly Valves:
Butterfly valves have a stem running through the middle, causing some obstruction in the flow path. However, this obstruction is minimal and does not significantly impact the performance of the valve in most brewing applications. Despite this, butterfly valves are still widely used in breweries due to their other advantages. While butterfly valves do cause a slight pressure drop due to the central stem, this drop is generally not substantial enough to affect the overall brewing process. The trade-off is considered acceptable given the other benefits butterfly valves offer.
Viscosity Handling and Cost Considerations in Brewing Valves
Butterfly Valves:Thicker mediums like wort can cause buildup in butterfly valves due to the stem, which can obstruct the flow and lead to potential maintenance issues. Brewers need to ensure regular cleaning and inspection to prevent such buildup. Butterfly valves are generally more expensive than ball valves of the same size. However, the higher cost is often justified by their ease of cleaning, hygienic design, and overall efficiency in brewing operations.
Ball Valves:
Ball valves handle viscous fluids better as they provide a clear, unobstructed path when open. This makes them a preferable choice for handling thicker liquids without the risk of clogging. Ball valves are typically less expensive, making them an attractive option for brewers on a budget. However, the potential for higher maintenance costs and the risk of contamination might offset the initial savings.
Conclusion
In summary, while ball valves have some advantages, butterfly valves are preferred in breweries for their ease of cleaning, good sanitary design, and adequate flow control, despite the slightly higher cost. Many brewers, both commercial and homebrewers, have transitioned to using butterfly valves throughout their systems.
