Food safety is the top concern of the public. Therefore, people have kept a close eye on the sanitary conditions in the canteens, food processing factories, and all kinds of places providing food. So the responsible person will be sensitive to the building materials.


The food industry involves the use of chaemical-free and user-friendly sanitary fittings. The fixtures are of food-grade quality, including sanitary couplings, stainless steel fittings, tri-clamp fittings, and more. These parts are corrosion-resistant, easy to fix, and follow global quality standards.


If you are searching for a reliable company that offers high-quality, food-grade sanitary couplings, continue to read this article ahead. 


What are Sanitary Fittings?

Sanitary fittings are minor parts used to connect two ferrules. They are also referred to as sanitary clamps or hygienic clamps. These fittings are often simple to install and secure connections between the equipment without producing breeding grounds for bacteria and fungi. 


These fittings provide better levels of joint cleanliness due to their unrivaled efficiency in installation, maintenance, and disassembly times. Therefore, they are necessary for the food, pharmaceutical, and biotechnology sectors.


#1 Types of Sanitary Fittings

Sanitary couplings or fittings should be sterilizable and made of corrosion-resistant materials, meaning that they can perform well even exposed to chemicals, high temperature, and high pressure. The commonly seen sanitary couplings include:

  • Ferrules
  • Nuts
  • SMS Female
  • Tri-clamp coupling
  • Weld reducer
  • Cross weld
  • Others


#2 Materials used for Sanitary Fittings

Stainless steel is the major material for sanitary couplings since the 

stainless-steel piping and fittings are available to withstand the constant abrasion and enjoy a longer service lifespan. However, stainless steel also has two types: 304 and 316. The latter has greater strength in coping with the abrasion-prone situation because of the added molybdenum, which can help resist corrosion to chlorides. Therefore, if the food processing places are constantly exposed to chemicals, 316 sanitary couplings are the most suitable.



A sanitary fitting’s surface with rougher textures might provide hiding places for bacteria and make cleaning more challenging. Instead of conventional rubber goods, all these fittings are often used with gaskets made of food-grade rubber.


Union Metal – The Go-To Company for Sanitary Fittings 

Union Metal, the global leading Camlock fittings supplier, is committed to offering sanitary couplings of all kinds to cater to the market’s demands. Some of our fitting for the food industry are listed below:


  • Tri-Clamps Fittings

Tri-clamp fittings, or tri-clover, are designed from 304/316L stainless steel and used with silicone rubber, EPDM, and PTFE gaskets. The working pressure is approximately 250 Psi, keeping it leak-proof, corrosion-resistant, and safe, which comes in sizes of 1″ to 4″ inches.


We provide 15 kinds of tri-clamp fittings that can cover all the applications. These couplings are used in different industries, such as beer, food, pharmaceutical, biochemical, cosmetics, etc., that should follow high sanitary standards.


  • DIN 11851 Fittings

DIN 11851 sanitary fittings consist of a clutch thread with coarse, rounded thread edges, making it easier to clean. These fittings are made from SS 304/316L and are optimal for liquid retention. The group contains female and male fittings, ferrule, nut, and weld. 


  • SMS Fittings

These connectors are specially designed for the food and beverage industry as they are corrosion-resistant, hygienic, and safe to use. SMS fittings’ working pressure is 10bar and is used with different gaskets, including EPDM, PTFE, and silicon rubber.


Key Takeaway! 

Sanitary fittings ideally serve as a central component in the food and beverage industry in terms of hygiene and performance. They keep the user safe from bacteria and other pests, reducing the chances of illness or any contagious disease. Although every industry has its manufacturing standards to follow, Union Metal is a cut above the rest. 


We are experienced manufacturers with skilled labor forces and sophisticated mechanisms to cater to the quality and performance of sanitary fittings in different industries. Contact us today for an affordable offering that won’t disappoint you.
