SMS Couplings

SMS couplings, also known as Swedish Metric Standard couplings, are a type of sanitary fitting widely used in the dairy, food, beverage, and pharmaceutical industries. These couplings are designed to meet the Swedish standard SMS 1145, which dictates specific dimensions and qualities to ensure a high level of hygiene.

Industrial Hoses

Industrial hoses are robust, flexible tubes designed to convey fluids, gases, or granular materials under varying conditions and pressures. These hoses are employed across a diverse range of industries, including petrochemical, food processing, construction, and manufacturing, to name just a few. Made from materials such as rubber, PVC, or metal, they can be reinforced with layers of textile, wire, or other synthetic materials for added strength and durability.

Clips & Clamps

Hose clips and clamps are mechanical devices specifically designed to secure hoses onto fittings, thereby preventing unwanted fluid leakage or detachment. These components are vital in various applications, such as automotive systems, industrial machinery, and plumbing. Made from materials like stainless steel, plastic, or even heavy-duty rubber, hose clips and clamps can range from simple wire forms to more elaborate quick-release or adjustable types.

SMS (Swedish Metric Standard) couplings are popularly used in the pharmaceutical, food, and beverage industries. They are known for their hygienic design and are commonly used for applications that require frequent cleaning and a secure, sanitary connection. Below are some of the primary benefits of using SMS couplings:

Hygienic and Clean

  1. Sanitary Design: SMS couplings are designed to meet strict hygienic standards, making them ideal for applications that require sanitary conditions, such as pharmaceutical, food, and beverage production.

  2. Ease of Cleaning: The couplings are usually designed to be easy to disassemble for cleaning, and they are often compatible with Clean-In-Place (CIP) systems.

Secure and Reliable

  1. High Seal Integrity: The gasket and clamp design of SMS couplings ensure a secure and leak-proof connection.

  2. Robust Construction: These couplings are usually made of high-grade stainless steel, offering durability and reliability.


  1. Various Applications: Although particularly favored in the food, beverage, and pharmaceutical sectors, SMS couplings are versatile and can be used in a range of applications that require hygienic and secure connections.

  2. Standardized Sizes: SMS couplings come in standardized sizes, making it easy to find replacements or additional components as needed.

Ease of Use

  1. Quick Assembly and Disassembly: SMS couplings can be quickly assembled and disassembled, saving time during both initial setup and subsequent maintenance or cleaning.

  2. User-Friendly: The design is generally straightforward, and it's often easy to tell visually whether the coupling has been properly secured, reducing the risk of errors during installation.


  1. Long-Lasting: Made of materials that are corrosion-resistant and capable of withstanding frequent cleaning, these couplings are designed for long-term use.

  2. Low Maintenance: The need for minimal maintenance can be a cost advantage over the long term.


  1. Economical Over the Long Term: Although the initial investment may be higher than for some other types of couplings, the durability and low maintenance requirements often make SMS couplings cost-effective over time.

Safety and Compliance

  1. Safety Standards: SMS couplings usually meet or exceed safety and sanitary standards, providing an extra layer of assurance in sensitive applications.

  2. Reduced Contamination Risk: The secure and hygienic design minimizes the chances of leakage or contamination, which is a crucial benefit in industries that require high levels of sanitation.

Material Options

  1. Material Flexibility: While stainless steel is the most common material used for these couplings due to its hygienic properties, they can also be made from other materials for specialized applications.

  2. Gasket Options: The type of gasket used can be selected based on the application, further increasing the coupling's versatility.

As always, when choosing a coupling for your specific application, be sure to consider factors such as the material being transferred, the operating pressure and temperature, and compatibility with your existing systems. Always consult with experts or the manufacturer to ensure that you're selecting the most appropriate components.
