In common ASME BPE / 3A sanitary systems, small sizes (e.g. 1“-2”) 304, 304L, or 316L stainless steel Tri Clamp Fittings are used in general food, dairy, and pharmaceutical system weights, with working pressures typically up to 10 bar (~145 psi). In high purity or high pressure applications, you will need to select the appropriate model based on specific dimensions and certification standards.
NOTE: Under high temperature CIP/SIP cleaning conditions, the effective pressure rating may be slightly reduced depending on the gasket material used.
Yes. Typically 304, 304L, or 316L stainless steel is used with silicone or PTFE gaskets. For ultra-high vacuum or precision semiconductor processes, it is recommended that you perform a helium leak test and a pressure test to confirm interface tightness.
Stainless steel body (304, 304L, or 316L) sanitary Tri Clamp Fittings can generally withstand operating temperatures ranging from -196°C to 400°C. In practice, the key factor limiting temperature is usually the choice of gasket. For example, EPDM is a common choice in most food, dairy or beverage systems. It has a continuous operating temperature range of -40°C ~ 150°C. Silicone gaskets have a continuous operating temperature range of -60°C ~ 200°C. PTFE gaskets are -200°C ~ 260°C. FKM gaskets are -20°C ~ 200°C. If SIP/CIP is involved, PTFE or high temperature resistant silicone gaskets are recommended.
Sanitary Tri Clamp Fittings can be used in low or medium-low pressure steam systems such as SIP steam sterilization lines, cleaning auxiliary steam branch lines, and discontinuous high-pressure steam environments. It can also be used in food grade compressed air, carbon dioxide, nitrogen and other inert or process auxiliary gas systems. However, you must make a factory evaluation based on your project’s operating pressure, operating temperature and gasket material before use, and cannot select directly from conventional liquid standards. For high-pressure industrial steam mains (e.g., power steam systems) or flammable gas systems, it is often preferred that you use welded connections and follow local pressure vessel and piping codes for proper selection.
OMSS’s sanitary Tri Clamp Fittings are manufactured using precision machining technology, which enables them to fit perfectly with sealing gaskets and have high piping system adaptability. Through CNC machining, the transition of the inner cavity flow path can be controlled stably, reducing fluid retention.
OMSS’s Sanitary Tri Clamp Fittings are typically made of 304 or 316L stainless steel and are ideal for prolonged contact with food, dairy, beverage and pharmaceutical fluids. Resistant to detergents and sanitizers, 316 stainless steel Tri Clamp Fittings are the preferred choice for highly corrosion-resistant and ultrapure environmental systems. Because of its higher nickel content, it is more resistant to chlorinated and oxidizing media.
OMSS’s sanitary Tri Clamp Fittings typical lead time is 5-7 business days for small orders and 10-14 business days for medium orders. For orders involving special sizes, surface finishes or light customization and large quantities, lead times are approximately 15-20 business days. For ultra-large volume or highly customized orders, lead times extend to 20-30 business days. For expedited production or any other needs, feel free to contact us to make arrangements.
What is Sanitary Tri Clamp Fitting?
Tri Clamp Fitting is a kind of sanitary connection used in industries with high requirements for environmental hygiene. It usually consists of a collar, a sealing gasket and a clamp. It is very easy to install and disassemble. By providing a reliable mechanical connection, it can ensure the stable transportation of fluids. It also reduces the risk of contamination. It is capable of connecting pipes of different diameters and supports modular system layouts through a reducer. It can be integrated with valves or other fittings to realize flexibility in process design.
How to Choose the Right Size Sanitary Tri Clamp Fittings?
You need to confirm the outer diameter (OD) and wall thickness (WT) of your project piping to ensure that the Tri Clamp Fitting and the piping interface can be accurately matched. For different process piping, you can refer to standard dimension tables, such as 3A, DIN, IDF or BPE standards, to select corresponding sizes of Tri Clamp Fittings. You should take into account the flow requirements and the pressure rating of the system, and select concentric or eccentric reducers where necessary. This ensures smooth flow and reduces stagnation or gas buildup. For high-purity or high-pressure systems, you’ll also need to pay attention to the fit tolerance and finish grade of the fittings to avoid degradation of the piping over a long period of time. For customized projects, we’ll take into account your piping layout and installation space to select the right type of connection, such as a ball valve, butterfly valve or adapter. Ensure your project is safe and reliable.

How to Properly Install Sanitary Tri Clamp Fittings?
Determine the Size and Material
Before installation, you need to make sure that the pipe and Tri Clamp Fittings size match. Select the appropriate sealing gasket (e.g., chemical and heat resistant gaskets) according to the project environment to ensure the sealing performance of the system.
Clean the Contact Surfaces
Clean the end surfaces of the pipe and Tri Clamp Fittings to remove dust, oil or machining residue. This step ensures that the gasket will fit perfectly.
Place the Gasket
Place the gasket between the Tri Clamp Fittings and clamp evenly. Make sure the gaskets are centered to prevent them from folding or curling, which could result in localized seal failure, leaks, or fluid blowout.
Install the Clamps
Slide the clamps into position on the fitting, tightening the single or double pin construction evenly to avoid localized indentation or leakage. Clamps that are too tight may crush gaskets or deform fittings, and clamps that are too loose may not ensure a tight seal.
Check Alignment and Tightening
Verify that the pipe and Tri Clamp Fittings axes are aligned and that the clamps are clamped evenly and not too tight or too loose. Pipe offset or uneven clamping can accelerate material fatigue or even cause fittings to rupture in long-term operation.
System Testing
Perform a pressure test or leakage check after completing the installation to confirm that the connections are sealed and the piping system is operating stably before putting it into service. For systems that require monitoring or venting, the installation can be aided by a sight glass or venting valve.
How to Maintain Sanitary Tri Clamp Fittings？
Periodically inspect clamps, gaskets and fitting surfaces for wear, corrosion or residue. For high-temperature or high-pressure lines, you’ll need to check the elasticity and surface integrity of gaskets. Clean removable parts individually. Clean the internal flow path of the line to ensure that there is no residue or microbial growth. Reinstall gaskets and clamps after cleaning, and periodically pressure test and leak test critical systems to ensure long-term operational safety.
